SUMMARY OF INVENTION
PROBLEM TO BE SOLVED BY THE INVENTION
[0004] However, since the above-described periphery monitoring apparatus causes the image of the mobile body to move in the display image, there has been a problem in that it is hard for occupants to watch the display image.
[0005] The present invention has been made in view of the above, and provides a periphery monitoring apparatus that is capable of displaying a display image easy for the occupants to watch.
MEANS FOR SOLVING PROBLEM
[0006] For solving the above problem, a periphery monitoring apparatus includes: an image capturing unit configured to generate a captured image by capturing a periphery of a mobile body; and a controller configured to generate, from the captured image, a peripheral image representing a view from a virtual viewpoint that is set at a relative position to a current position of the mobile body depending on a movement of the mobile body, generate a display image in which a mobile body image representing a position of the mobile body is superimposed on the peripheral image, and display the mobile body image to fix a position of the mobile body image in the display image.
[0007] Since the periphery monitoring apparatus fixes the position of the mobile body image in the display image, it is possible to display the display image easy for the occupant to watch.
[0008] In the periphery monitoring apparatus according to the present invention, the controller may generate, as the peripheral image, an image representing a view of the captured image from the virtual point, the captured image being projected onto a three-dimensional virtual projection plane including a first virtual plane and a second virtual plane intersecting with the first virtual plane. As a result, in comparison with the case where the peripheral image is generated from a captured image projected onto a two-dimensional virtual projection plane, the periphery monitoring apparatus can suppress the extension of the image of an object extending in the vertical direction (for example, a utility pole) in the periphery of the mobile body and generate a peripheral image that is easy for the occupant to watch.
[0009] In the periphery monitoring apparatus according to the present invention, the controller may move the virtual viewpoint in accordance with an input from a user. As a result, the periphery monitoring apparatus can provide a display image including a peripheral image representing a view from a virtual viewpoint desired by the user.
[0010] The periphery monitoring apparatus according to the present invention further includes a storage unit configured to store a three-dimensional mobile body shape model that is a three-dimensional shape model of the mobile body. In the periphery monitoring apparatus, the mobile body image may be generated from the three-dimensional mobile body shape model stored in advance in the storage unit. By superimposing a three-dimensional mobile body image, the periphery monitoring apparatus can provide a display image that is easier to watch.

DESCRIPTION OF EMBODIMENTS
[0012] In the following exemplary embodiments and the like, the same constituent elements are denoted by common reference signs and the redundant explanations thereof are omitted as appropriate.
[0013] FIG. 1 is an exemplary perspective view illustrating a state where a part of a passenger compartment 2a of a vehicle 1 according to a first embodiment is seen through. The vehicle 1 may be, for example, an automobile with an internal combustion engine (an engine, not illustrated) as a drive source (an internal-combustion engine vehicle), an automobile with an electric motor (a motor, not illustrated) as a drive source (an electric vehicle, a fuel-cell vehicle, or the like), or an automobile with both of the foregoing as a drive source (a hybrid vehicle). The vehicle 1 can be equipped with various types of transmissions and various devices (systems, components, and others) that are needed to drive the internal combustion engine or the electric motor. The method, the number, the layout, and others of the devices concerning the drive of wheels 3 in the vehicle 1 can be set in various ways.
[0014] As illustrated in FIG. 1, the vehicle 1 includes a vehicle body 2, a steering unit 4, an acceleration operating unit 5, a braking operating unit 6, a speed-change operating unit 7, and a monitor device 11.
[0015] The vehicle body 2 constitutes the passenger compartment 2a in which occupants not illustrated ride in. In the passenger compartment 2a, the steering unit 4, the acceleration operating unit 5, the braking operating unit 6, the speed-change operating unit 7, a display device 8, a sound output device 9, an operation input unit 10, and the like are provided to face a seat 2b for a driver as an occupant. The vehicle body 2 includes a front bumper provided at the lower portion of the front end portion and a rear bumper provided at the lower portion of the rear end portion.
[0016] The steering unit 4 is a steering wheel projecting from a dashboard, for example. The acceleration operating unit 5 is an accelerator pedal positioned under the foot of the driver, for example. The braking operating unit 6 is a brake pedal positioned under the foot of the driver, for example. The speed-change operating unit 7 is a shift lever projecting from a center console, for example. The steering unit 4, the acceleration operating unit 5, the braking operating unit 6, and the speed-change operating unit 7 are not limited to the above.
[0017] The monitor device 11 is provided in a central portion in a vehicle width direction of the dashboard, that is, a left-and-right direction of the dashboard, for example. The monitor device 11 may have a function such as a navigation system or an audio system. The monitor device 11 includes the display device 8, the sound output device 9, and the operation input unit 10. The monitor device 11 may include an operation input unit, which is not illustrated, such as a switch, a dial, a joystick, and a push button.
[0018] The display device 8 displays an image on the basis of image information. The display device 8 is a liquid crystal display (LCD), or an organic electroluminescent display (OELD), for example.
[0019] The sound output device 9 outputs sound on the basis of audio data. The sound output device 9 is a speaker, for example. The sound output device 9 may be provided at a position in the passenger compartment 2a other than the monitor device 11.
[0020] The operation input unit 10 receives an input of the occupant. The operation input unit 10 is a touch panel, for example. The operation input unit 10 is provided on a display screen of the display device 8. The operation input unit 10 is configured such that an image displayed by the display device 8 can be transmitted through it. Accordingly, the operation input unit 10 enables the occupant to visually recognize the image displayed on the display screen of the display device 8. The operation input unit 10 receives an instruction that is input by touching a position corresponding to the image displayed on the display screen of the display device 8 by the occupant.
[0021] FIG. 2 is an exemplary plan view of the vehicle 1. As illustrated in FIG. 1 and FIG. 2, the vehicle 1 is a four-wheeled vehicle and is provided with two left and right front wheels 3F and two left and right rear wheels 3R. All or a part of the four wheels 3 can be steered.
[0022] The vehicle 1 includes a plurality of image capturing units 15. Each of the image capturing unit 15 is a digital camera provided with a built-in imaging element such as a charge coupled device (CCD), or a CMOS image sensor (CIS). Each of the image capturing unit 15 is capable of outputting, as data of an image, the data of a moving image including a plurality of frame images generated at a certain frame rate, or the data of a still image. For example, each image capturing unit 15 generates, as a captured image, a still image in which the periphery of the vehicle 1 is captured, and outputs data of the captured image. The captured image may be a moving image or a still image. Each image capturing unit 15 is provided with a wide-angle lens or a fish-eye lens and is capable of photographing a range of 140° to 190° in the horizontal direction. The optical axis of the image capturing unit 15 is oriented obliquely downward. Accordingly, the image capturing units 15 output data of the captured images in which an external environment on the periphery of the vehicle 1 are captured, where periphery of the vehicle 1 includes a road surface on which the vehicle 1 can move.
[0023] In the first embodiment, four image capturing units 15a, 15b, 15c, and 15d are provided on the vehicle 1. The vehicle 1 may have three or less or five or more plural image capturing units 15. The image capturing unit 15a is provided at a central portion of the front portion of the vehicle 1, for example. The image capturing unit 15a photographs the peripheral environment in front of the vehicle 1. The image capturing unit 15b is provided at a central portion of the rear portion of the vehicle 1, for example. The image capturing unit 15b photographs the peripheral environment behind the vehicle 1. The image capturing unit 15c is provided at the end portion of the left-hand side of the vehicle body 2, for example, on a left-side door mirror 2g. The image capturing unit 15c photographs the peripheral environment of the left-hand side of the vehicle 1. The image capturing unit 15d is provided at the end portion of the right-hand side of the vehicle body 2, for example, on a right-side door mirror 2h. The image capturing unit 15d photographs the peripheral environment of the right-hand side of the vehicle 1.
[0024] FIG. 3 is a block diagram for explaining the configuration of the vehicle 1. As illustrated in FIG. 3, the vehicle 1 further includes a wheel speed sensor 22, an electronic control unit (ECU) 24, and an in-vehicle network 25. For example, the monitor device 11, the image capturing units 15, and the ECU 24 function as a periphery monitoring apparatus 50.
[0025] The wheel speed sensor 22 is a sensor that detects a rotation amount of the wheel 3 or a rotation speed thereof per unit time. The wheel speed sensor 22 outputs, as a sensor value, the number of wheel speed pulses representing the detected rotation speed. The wheel speed sensor 22 may be made up by using a hall element and the like.
[0026] The ECU 24 is a computer, for example. The ECU 24 receives captured image data from the image capturing unit 15. The ECU 24 transmits the data that concerns the image or the sound to be output to the monitor device 11. The ECU 24 includes a central processing unit (CPU) 24a, a read only memory (ROM) 24b, a random-access memory (RAM) 24c, a display controller 24d, an audio controller 24e, and a solid-state drive (SSD) 24f. The CPU 24a, the ROM 24b, and the RAM 24c may be integrated in the same package.
[0027] The CPU 24a reads out programs stored in a non-volatile storage device, such as the ROM 24b, and executes various arithmetic processes and control in accordance with the relevant programs. The CPU 24a executes image processing of images and the like for periphery monitoring displayed on the display device 8.
[0028] The ROM 24b stores the respective programs, parameters needed for executing the programs, and the like. The RAM 24c temporarily stores various data used in the calculation in the CPU 24a. The display controller 24d mainly executes, out of the arithmetic processes in the ECU 24, image processing of the image obtained by the image capturing unit 15, data conversion of display images to be displayed on the display device 8, and the like. The audio controller 24e mainly executes, out of the arithmetic processes in the ECU 24, processing of sound to be output to the sound output device 9. The SSD 24f is a rewritable non-volatile storage unit and it retains data even when the power supply of the ECU 24 is turned off.
[0029] In the first embodiment, the ECU 24 administers overall control of the vehicle 1 by the collaboration of hardware and software (a control program). For example, the ECU 24 calculates a travel distance of the vehicle 1, a vehicle speed thereof, and the like on the basis of the sensor value acquired from the wheel speed sensor 22, and executes various control. The ECU 24 generates a display image including a peripheral image on the basis of the captured image including the peripheral image captured by the image capturing unit 15, and causes the display device 8 to display the display image. Accordingly, the ECU 24 is implemented as the function of the periphery monitoring apparatus 50.
[0030] The in-vehicle network 25 is a controller area network (CAN), for example. The in-vehicle network 25 electrically connects the ECU 24, the operation input unit 10, and the wheel speed sensor 22 so that information such as a control signal and an operation signal can be transmitted and received among them.
[0031] FIG. 4 is a block diagram illustrating the functions of the ECU 24. As illustrated in FIG. 4, the ECU 24 includes a controller 30 and a storage unit 32. The controller 30 is implemented as the functions of the CPU 24a, the display controller 24d, and the audio controller 24e. The storage unit 32 is implemented as the functions of the ROM 24b, the RAM 24c, and the SSD 24f.
[0032] The controller 30 generates, from the captured image, a peripheral image representing a view from a virtual viewpoint set at a relative position to the current position of the vehicle 1 depending on a movement of the vehicle 1. The controller 30 generates a display image in which a vehicle image (one example of a mobile body image) representing the position of the vehicle 1 is superimposed on the generated peripheral image. The controller 30 displays the vehicle image to fix a position of the vehicle image in the display image. The controller 30 includes a determination unit 52 and an image generator 54. The controller 30 functions as the determination unit 52 and the image generator 54 by reading a program for image display stored in the storage unit 32. Note that the whole or part of the determination unit 52 and the image generator 54 may be implemented by hardware such as a circuit including an application-specific integrated circuit (ASIC).
[0033] The determination unit 52 executes determination needed in image display. Specifically, the determination unit 52 determines whether or not to display the display image including the peripheral image. For example, the determination unit 52 determines whether or not to display the display image including the peripheral image according to the speed of the vehicle 1 (that is, a vehicle speed). The determination unit 52 may determine whether or not to display the display image including the peripheral image depending on other situations such as the shift position of the speed-change operating unit 7. The determination unit 52 further determines whether or not to update the display image including the peripheral image. For example, the determination unit 52 determines whether or not to update the display image according to a moving distance of the vehicle 1. Furthermore, the determination unit 52 determines whether or not to terminate the display of the display image including the peripheral image. For example, the determination unit 52 determines whether or not to terminate the display of the display image including the peripheral image depending on whether the vehicle 1 has stopped.
[0034] The image generator 54 generates the display image to be displayed on the display device 8. Specifically, the image generator 54 acquires a captured image captured by the image capturing unit 15. The image generator 54 generates, from the captured image, a peripheral image representing a view from a virtual viewpoint set at a relative position to the current position of the vehicle 1 depending on a movement of the vehicle 1. For example, the image generator 54 generates, as the peripheral image, an image representing a view of a captured image from the virtual viewpoint. The captured image has been projected onto a preset virtual projection plane. The image generator 54 may generate, as the peripheral image, an image equivalent to the image representing a view of the captured image from the virtual viewpoint projected onto the above-described virtual projection plane by using a graphics processing unit (GPU) or the like without generating an intermediate image that is obtained by projecting the captured image onto the virtual projection plane. The image generator 54 generates a display image by superimposing the vehicle image onto the generated peripheral image. Here, the image generator 54 fixes the position of the vehicle image in the display image. The vehicle image is stored in advance in the storage unit 32, for example. The image generator 54 causes the display device 8 to successively display the generated display image.
[0035] The storage unit 32 stores programs executed by the controller 30, data needed for executing the programs, and the like. For example, the storage unit 32 stores a program for image display. The storage unit 32 stores, as the data needed for executing the program for image display, a threshold vehicle speed for determining whether to display the display image including the peripheral image, the virtual projection plane onto which the captured image is projected, and data related to the vehicle image. The storage unit 32 may be a storage device or the like provided on a network (for example, a cloud).
[0036] FIG. 5 is a flowchart of image display processing executed by the controller 30. The controller 30 functions, by reading the program for image display, as the determination unit 52 and the image generator 54 and executes the image display processing.
[0037] In the image display processing, the determination unit 52 of the controller 30 determines whether or not to display the display image including the peripheral image (S102). For example, the determination unit 52 determines whether or not to display the display image including the peripheral image depending on whether the vehicle speed calculated based on the sensor value acquired from the wheel speed sensor 22 is below the predetermined threshold vehicle speed. One example of the threshold vehicle speed is 10 km/h. In this case, when the vehicle speed is below the threshold vehicle speed, the determination unit 52 determines to display the display image including the peripheral image. On the other hand, when the vehicle speed is greater than or equal to the threshold vehicle speed, the determination unit 52 determines not to display the display image including the peripheral image. The determination unit 52 may determine whether or not to display the display image on the basis of an operation instruction by the occupant received via the operation input unit 10.
[0038] When it is determined not to display the display image including the peripheral image (No at S102), the determination unit 52 turns into a standby state. On the other hand, when it is determined to display the display image including the peripheral image (Yes at S102), the determination unit 52 outputs a display instruction to the image generator 54.
[0039] The image generator 54 generates the peripheral image upon acquiring the display instruction from the determination unit 52 (S104). For example, the image generator 54 acquires from the storage unit 32 a past captured image captured by the image capturing unit 15, and generates, as the peripheral image, an image representing a view of the past captured image from the virtual viewpoint. The past captured image has been projected onto the virtual projection plane.
[0040] FIG. 6 is a diagram for explaining a virtual space 66 including a virtual projection plane 60 on' which a past captured image is projected. FIG. 7 is a side view of the virtual projection plane 60 from a lateral side. The X and Z depicted with arrows in FIG. 6 are defined as an X direction and a Z direction. The Y depicted with an arrow in FIG. 7 is defined as a Y direction. FIG. 6 is a schematic plan view of the vehicle 1 and the periphery of the vehicle 1 in the virtual space 66.
[0041] The image generator 54 acquires, from the storage unit 32, a past captured image captured by the image capturing unit 15 of the vehicle 1 that was at an imaged position PT0 being a position of the vehicle 1 at the time when the past captured image was captured. The image generator 54 acquires information relating to the preset virtual projection plane 60 (for example, information such as the size and the position of the virtual projection plane 60) from the storage unit 32. The image generator 54 sets, in the three-dimensional virtual space 66 illustrated in FIG. 6, the three-dimensional virtual projection plane 60 on the moving direction side of the imaged position PT0 (for example, the front side). The virtual projection plane 60 includes a first virtual plane 62, and a second virtual plane 64 continuous with the first virtual plane 62. The first virtual plane 62 is parallel to an XZ plane (that is, the horizontal plane). The second virtual plane 64 is parallel to a YZ plane (that is, the vertical plane). That is, the second virtual plane 64 intersects with the first virtual plane 62. The end portion on the moving direction side of the first virtual plane 62 is coupled to the lower end portion of the second virtual plane 64. The image generator 54 generates, as the peripheral image, an image representing a view of the past captured image from the virtual viewpoint. The past captured image has been projected onto the three-dimensional virtual projection plane 60.
[0042] The generation of a peripheral image 72a by the image generator 54 will be specifically described. FIG. 8 is a diagram for explaining the generation of the peripheral image 72a by the image generator 54. FIG. 8 is a schematic plan view of the vehicle 1 and the periphery of the vehicle 1 in the virtual space 66 in a state where the vehicle 1 has moved from the imaged position PT0 in FIG. 6 to a virtual position PT1 along a bold arrow AR1. In FIG. 8, the vehicle 1 at the imaged position PT0 is depicted with a dotted line.
[0043] As illustrated in FIG. 8, the image generator 54 sets in the virtual space 66 the virtual position PT1 of the vehicle 1 corresponding to the current position of the vehicle 1 in the real space (for example, a world coordinate). The image generator 54 generates, as the peripheral image 72a, an image representing a view of the captured image from a virtual viewpoint VV1 that is set based on the virtual position PT1 of the vehicle 1. The captured image has been projected onto the virtual projection plane 60. The image generator 54 defines the virtual viewpoint VV1 as a starting point, and generates, as the peripheral image 72a, an image that is visible in an area within a predetermined angle (for example, a dotted area of FIG. 8) from the areas on both sides of a virtual line of vision defined as a direction along the moving direction (for example, the front) from the starting point. The image generator 54 may arbitrarily set the position of the virtual viewpoint VV1 according to the current position of the vehicle 1 or the virtual position PT1. The image generator 54 of the first embodiment fixes the relative position of the virtual viewpoint VV1 to the current position of the vehicle 1 or the virtual position PT1 and moves the position of the virtual viewpoint VV1 depending on a movement the vehicle 1. For example, the image generator 54 sets the position of the virtual viewpoint VV1 at 1 m rearward and 2 m high with respect to the central axis of the vehicle 1 in planar view. In the first embodiment, although the virtual viewpoint VV1 coincides with the virtual position PT1, the embodiment is not limited to this case.
[0044] The image generator 54 generates a display image by superimposing, on the generated peripheral image 72a, a vehicle image 74 being an image of the vehicle 1 (S106).
[0045] FIG. 9 is one example of a display image 70a including the peripheral image 72a generated by the image generator 54. The image generator 54 generates the display image 70a illustrated in FIG. 9 by superimposing the vehicle image 74, which is the image of the vehicle 1, onto the virtual position PT1 of the vehicle 1 in the generated peripheral image 72a. In FIG. 9, although the vehicle image 74 is illustrated with the dotted area and a frame of dotted line, the embodiment is not limited to this case. The image generator 54 may generate the display image 70a in which a horizontal line 76 is drawn onto the captured image projected onto the second virtual plane 64.
[0046] The image generator 54 causes the display device 8 to display the generated display image 70a illustrated in FIG. 9 (S108).
[0047] The determination unit 52 determines whether or not to update the display image 70a (S110). Specifically, the determination unit 52 calculates the moving distance of the vehicle 1 on the basis of the vehicle speed calculated by using the sensor value acquired from the wheel speed sensor 22. The determination unit 52 determines whether or not to update the display image 70a depending on whether the moving distance is greater than or equal to a predetermined threshold distance. When the moving distance is below the threshold distance, the determination unit 52 determines not to update the display image 70a. On the other hand, when the moving distance is greater than or equal to the threshold distance, the determination unit 52 determines to update the display image 70a.
[0048] When it is determined not to update the display image 70a (No at S110), the determination unit 52 determines whether or not to terminate the display of the display image 70a (S112). The determination unit 52 determines whether or not to terminate the display of the display image 70a on the basis of whether the vehicle 1 has stopped. When it is determined not to terminate the display of the display image 70a (No at S112), the determination unit 52 repeats the step S110.
[0049] When it is determined to update the display image 70a (Yes at S110), the determination unit 52 outputs an update instruction to the image generator 54.
[0050] Upon acquiring the update instruction, the image generator 54 generates a new peripheral image 72b by the above-described generation method of the display image 70a, and updates a display image 70b (S104, S106). The image generator 54 may change only the peripheral image by using a different captured image every time. Furthermore, the image generator 54 may update the display image 70b by generating, as the new peripheral image 72b, an image representing a view of the same captured image from a virtual viewpoint that is moved depending on a movement of the vehicle 1. The same captured image has been projected onto the virtual projection plane 60 of the same virtual space 66. In other words, the image generator 54 may generate the peripheral images 72a and 72b from a single captured image.
[0051] The generation and updating of the display image 70b by the image generator 54 will be specifically described. FIG. 10 is a diagram for explaining the generation of the display image 70b by the image generator 54 in a state where the vehicle 1 has moved from that in FIG. 8. FIG. 11 is one example of the display image 70b updated by the image generator 54. In the following description, the display image 70a or 70b will be described as a display image 70 when there is no need to distinguish between them. Similarly, the peripheral image 72a or 72b will be described as a peripheral image 72 when there is no need to distinguish between them.
[0052] As illustrated in FIG. 10, even when the vehicle 1 has moved to a virtual position PT2 along an arrow AR2, the image generator 54 may generate, as the peripheral image 72b, an image representing a view of the same captured image from a virtual viewpoint VV2 which is moved based on the current position of the vehicle 1 that has moved. The same captured image has been projected onto the virtual projection plane 60 of the same virtual space 66. The image generator 54 generates and updates the display image 70b illustrated in FIG. 11 by superimposing the vehicle image 74 onto the position corresponding to the virtual position PT2 of the vehicle 1 in the generated peripheral image 72b. As illustrated in FIG. 11, the image generator 54 fixes the position of the vehicle image 74 without moving it in the display image 70b. Within the display images 70a and 70b illustrated in FIG. 9 and FIG. 11, the position and the shape of the vehicle image 74 are the same. In other words, the image generator 54 changes the peripheral images 72a and 72b alone in the display images 70a and 70b.
[0053] The image generator 54 causes the display device 8 to display the updated display image 70b (S108). Accordingly, as long as the update instruction is acquired from the determination unit 52, the image generator 54 generates and updates the display image 70 in which the vehicle image 74 is fixed.
[0054] In the step S112, when it is determined to terminate the display of the display image 70 (Yes at S112), the determination unit 52 terminates the display of the display image 70 and ends the image display processing.
[0055] As described above, in the periphery monitoring apparatus 50, the controller 30 generates the display image 70 in which the position of the vehicle image 74 is fixed in the display image 70. As a result, the periphery monitoring apparatus 50 can provide the display image 70 that is easy for the occupant to watch because the position of the vehicle image 74 is maintained even when the peripheral image 72 is changed as the vehicle 1 has moved.
[0056] When the image generator 54 generates, from a single captured image projected onto the virtual projection plane 60, a plurality of peripheral images 72 representing a view from the moving virtual viewpoint VV, the periphery monitoring apparatus 50 can reduce a processing load of the controller 30 for generating the peripheral image 72.
[0057] In the periphery monitoring apparatus 50, the controller 30 generates, as the peripheral image 72, an image representing a view of the captured image from the virtual viewpoint VV, where the captured image has been projected onto the three-dimensional virtual projection plane 60 including the continuous first virtual plane 62 and the second virtual plane 64. As a result, in comparison with the case where the peripheral image is generated from a captured image projected onto a two-dimensional virtual projection plane, the periphery monitoring apparatus 50 can generate the peripheral image 72 that is easy for the occupant to watch. In particular, when an object extending in the vertical direction (for example, a utility pole) exists in the periphery of the vehicle 1, the image of the object two-dimensionally projected extends more than the actual object. On the other hand, by projecting the image on the virtual projection plane 60 having the second virtual plane 64, the controller 30 can suppress the extension of the image of the object and generate the peripheral image 72 that is easy to watch.
First Modification
[0058] Next, a virtual projection plane 60b of a first modification where the virtual projection plane 60 of the above-described first embodiment is modified will be described. FIG. 12 is a side view of the virtual projection plane 60b according to the first modification. As illustrated in FIG. 12, the virtual projection plane 60b has a bowl shape and includes the first virtual plane 62 and a second virtual plane 64b. The second virtual plane 64b is formed in a curved surface shape bending in the vertical direction. For example, the second virtual plane 64b is formed in a curved surface shape projecting in the moving direction (+Z direction, in the example illustrated in FIG. 12). The lower end portion of the second virtual plane 64b is coupled to the end portion on the moving direction side of the first virtual plane 62. The controller 30 may generate, as a plurality of peripheral images, a plurality of images representing a view of captured image from a virtual viewpoint that is moved depending on a movement of the vehicle 1. The captured image has been projected onto the same virtual projection plane 60b.
Second Modification
[0059] Next, a virtual projection plane 60c of a second modification for which the virtual projection plane 60 of the above-described first embodiment is modified will be described. FIG. 13 is a side view of the virtual projection plane 60c according to the second modification. As illustrated in FIG. 13, the virtual projection plane 60c includes the second virtual plane 64. In other words, the virtual projection plane 60c has a configuration in which the first virtual plane 62 is omitted from the virtual projection plane 60 of the first embodiment. The controller 30 may generate, as a plurality of peripheral images, a plurality of images representing a view of captured image from a virtual viewpoint that is moved depending on a movement of the vehicle 1. The captured image has been projected onto the virtual projection plane 60c.
[0060] The following describes a second embodiment in which the generation method of the peripheral image 72 is different from that of the first embodiment. FIG. 14 is a diagram illustrating relation between a virtual viewpoint and a virtual projection plane according to the second embodiment. The display image processing of the second embodiment will be described along the flowchart in FIG. 5.
[0061] As illustrated in FIG. 14, the image generator 54 of the controller 30 sets a virtual viewpoint VV3 on the basis of the current position of the vehicle 1. The image generator 54 sets a planar virtual projection plane 60d on the basis of the virtual viewpoint VV3. The image generator 54 generates, as the peripheral image 72, a viewpoint image in which a past captured image captured at the imaged position PT0 illustrated in FIG. 6 is projected onto the virtual projection plane 60d (S104). The image generator 54 generates and displays the display image 70 including the peripheral image 72 and the vehicle image 74 (S106, S108).
[0062] Thereafter, when updating the display image depending on a movement of the vehicle 1 (Yes at S110), by repeating the processing at and subsequent to the step S104 as illustrated in FIG. 5, the image generator 54 newly sets a virtual viewpoint and a virtual projection plane, and generates and updates the display image 70 from the same captured image. In other words, the image generator 54 generates, as a plurality of peripheral images 72, a plurality of viewpoint images generated by projecting the captured image onto a plurality of virtual projection planes 60d, ... set on the basis of the respective virtual viewpoints VV3, ... moved depending on the movement of the vehicle 1. Also in the second embodiment, the image generator 54 fixes the position of the vehicle image 74 in the display image.
[0063] The functions, the connection relations, the arrangements, the numbers, and others of the respective configurations of the above-described embodiments may be modified as appropriate. Furthermore, the respective embodiments or modifications may be combined.
[0064] For example, in the above-described embodiments, although the image generator 54 has set the position of the virtual viewpoints VV1, VV2, ... as 1 m rearward and 2 m high with respect to the central axis of the vehicle 1 in planar view, the embodiments are not limited to this case. Although the image generator 54 sets the direction of the virtual line of vision having the starting point of the virtual viewpoints VV1, VV2, ... as the moving direction of the vehicle 1, the embodiments are not limited to this case. For example, the image generator 54 may set the direction of the virtual line of vision having the starting point of the virtual viewpoints VV1, VV2, ... as the direction of the image capturing unit 15 (for example, the optical axis direction of the lens of the image capturing unit 15). As a result, the controller 30 can reduce the discomfort felt by occupants who watch the above-described display image 70. In particular, when displaying by switching the peripheral image being captured by the image capturing unit 15 and the above-described display image 70, the controller 30 can further reduce the discomfort of the occupants because the viewpoint and the line of vision do not shift.
[0065] In the above-described embodiments, the example has been described, in which the image generator 54 generates the display image 70 including the peripheral image 72 generated from a captured image that is captured by a single image capturing unit 15. The embodiments are not limited to this case. For example, the image generator 54 may generate a display image including the peripheral image generated from a plurality of captured images that are captured by a plurality of image capturing units 15.
[0066] In the above-described embodiments, the example has been described, in which the display image 70 including the peripheral image 72 representing a view from the virtual viewpoint VV set by the image generator 54 is displayed. The embodiments are not limited to this case. For example, by receiving an instruction input by the user via the operation input unit 10 such as a touch panel, the image generator 54 may generate and display a display image including a peripheral image representing a view from a virtual viewpoint with the current position of the vehicle 1 as a reference. In this case, the image generator 54 may generate the display image including the peripheral image by moving the virtual viewpoint, which is a virtual viewpoint set with the current position of the vehicle 1 as a reference and is a virtual viewpoint looking at the direction of one gazing point, on the circumference in accordance with the input of the user, for example. Furthermore, the image generator 54 may generate a peripheral image representing a view from a virtual viewpoint that the user selected out of a plurality of virtual viewpoints set with the current position of the vehicle 1 as a reference. As a result, the image generator 54 can provide a display image including a peripheral image representing a view from the virtual viewpoint desired by the user.
[0067] In the above-described embodiments, although it has been described with the two-dimensional vehicle image 74 as an example, the embodiment is not limited to this case. For example, the image generator 54 may generate a vehicle image from a three-dimensional mobile body shape model stored in advance in the storage unit 32. The three-dimensional mobile body shape model is a three-dimensional shape model of the vehicle 1.
[0068] FIG. 15 is one example of a display image 270 in which a three-dimensional vehicle image 274 is superimposed on a peripheral image 272 when the virtual viewpoint VV is set inside the vehicle 1. For example, as illustrated in FIG. 15, the image generator 54 may generate the display image 270 by setting the virtual viewpoint VV inside the vehicle 1, and superimposing the three-dimensional vehicle image 274 (see dotted lines) on the peripheral image 272 viewing the moving direction (for example, the front). As a result, the image generator 54 can provide the display image 270 that is more easily viewable.
[0069] FIG. 16 is one example of a display image 370 in which a three-dimensional vehicle image 374 is superimposed on a peripheral image 372 when the virtual viewpoint VV is set outside the vehicle 1. For example, as illustrated in FIG. 16, the image generator 54 may generate the display image 370 by setting the virtual viewpoint VV outside the vehicle 1 (for example, the left-hand side of the vehicle 1), and superimposing the three-dimensional vehicle image 374 (see dotted lines) on the peripheral image 372 viewing the moving direction (for example, the front). As a result, the image generator 54 can provide the display image 370 that is more easily viewable. Furthermore, by superimposing the vehicle image 274 or 374 semi-transparently, it makes it easy to grasp the positional relation between the vehicle image 274 or 374, and the objects photographed by the image capturing unit 15.
[0070] While the embodiments and the modifications of the present invention have been exemplified, these embodiments and the modifications described herein are presented as mere examples and are not intended to limit the scope of the invention. Those novel embodiments described herein may be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the scope of the invention.

Medal of Honor sells 1.5 million & Clean Sweep DLC revealed
Posted on October 20, 2010 by Train2Game Blogger Team
EA has announced that over 1.5 million copies of Medal of Honor have been sold worldwide in just five days. Medal of Honor was released in the USA on October 12th, while the European release followed three days later.
The data on Medal of Honor sales comes from GFK Chart Track data. Of course, Medal of Honor took top spot in the GFK Chart Track UK chart this week, dislodging fellow EA title FIFA 11 in the process.
EA are pleased with sales of Medal of Honor, despite mediocre reviews from critics. Frank Gibeau, President at EA said:
"Medal of Honor is one of EA's most storied franchises and we're thrilled to see that fans worldwide have embraced it. In this ultra competitive category, Medal of Honor stands out from the pack. By portraying the Tier 1 Operator as so elite, so tough, Medal of Honor offers a view into a world that has the power to resonate with FPS gamers everywhere."
Meanwhile, EA CEO John Ricitiello has told Fox News that Medal of Honor has so far made $100 million. An impressive amount, but some way off the $200 million that Halo: Reach made in its first day on sale. The $100 million made by Medal of Honor is only a fraction of the $550 million Call of Duty: Modern Warfare 2 made in its first five days.
EA also announced that Medal of Honor will shortly be getting free DLC. The free multiplayer mode titled Clean Sweep is an elimination mode where players must rely on their own skill and teammates' expertise to prevail as the winning team. The new Medal of Honor multiplayer mode will be playable on two new maps – Bagram Hangar and Khyber Caves – as well as redesigned versions of the Diwagal Camp and Kabul City Ruins maps.
The new Medal of Honor game mode will consist of three four minute rounds with no respawns. The team who gets the best of the three rounds wins. You can watch the trailer for the Medal of Honor Clean Sweep DLC below.
Clean Sweep will be available on November 2 via Xbox LIVE Marketplace and PlayStation Network to owners of Medal of Honor with Online Pass. The free, single use Online Pass comes with all brand new copies of Medal of Honor.
So Train2Game, what are your thoughts on the achievements of Medal of Honor? And what do you think of the Clean Sweep DLC? Is it enough to encourage you to hold onto your copy of Medal of Honor? Not familiar with the game? You can watch the Medal of Honor launch trailer here.

Nigerian President Muhammadu Buhari's wife has warned him that she may not back him at the next election unless he shakes up his government.
In a BBC interview, Aisha Buhari said the president "does not know" most of the top officials he has appointed.
She suggested the government had been hijacked, saying a "few people" were behind presidential appointments.
Mr Buhari was elected last year with a promise to tackle corruption and nepotism in government.
His wife's decision to go public with her concerns will shock many people, but it shows the level of discontent with the president's leadership, says the BBC's Naziru Mikailu in the capital, Abuja.
The president famously remarked at his inauguration that he "belongs to nobody and belongs to everybody".
In the interview with Naziru Mikailu, Mrs Buhari said: "The president does not know 45 out of 50, for example, of the people he appointed and I don't know them either, despite being his wife of 27 years."
She said people who did not share the vision of the ruling All Progressives Congress (APC) were now appointed to top posts because of the influence a "few people" wield.
"Some people are sitting down in their homes folding their arms only for them to be called to come and head an agency or a ministerial position."
Asked to name those who had hijacked the government, she refused, saying: "You will know them if you watch television."
On whether the president was in charge, she said: "That is left for the people to decide."
Mrs Buhari said her husband had not told her whether he would contest the 2019 election.
"He is yet to tell me but I have decided as his wife, that if things continue like this up to 2019, I will not go out and campaign again and ask any woman to vote like I did before. I will never do it again."
Asked what she regarded as the government's major achievement, she said it was to improve security in the north-east where militant Islamist group Boko Haram has waged an insurgency since 2009.
"No-one is complaining about being attacked in their own homes. Thankfully everyone can walk around freely, go to places of worship, etc. Even kids in Maiduguri have returned to schools," Mrs Buhari said, referring to the city which was once the headquarters of the militant group.
Good woman saying exactly what's on her mind. Many APC faithful feel the same way as this woman.
Zombies will call her a wailer.
Even Job's wife told him to curse God and die. the end justifies the means.
Aisha cannot say all this. Even if she did, she must have been deceived by the ever cunning power hungry enemy. My Sai Buhari should be very careful with this enemies going forward. They want to destroy him using his loved ones. We know the dark and diabolical hards behind this show of shame. They only want to push the "more loyal king's men" away and then draw the long swords on him. Daura and Kyari are more important in this government of change than any delusional power hungry schemer. I trust my Sai baba to handle this "storm in the teacup" being stirred covertly by the cowardly mortley mob.
"He is yet to tell me but I have decided as his wife, that if things continue like this up to 2019, I will not go out and campaign again and ask any woman to vote like I did before. I will never do it again.
These are strong words from the first lady and I commend her for having the courage to speak out in this manner. She's probably frustrated with Daura and Kyari who have refused to allow her wield any influence in the Buhari government.
I hope the president act quickly and resolve some of these issues. His party is already in crisis, he cannot afford another crisis among members of his immediate family.
I dislike Buhari but this woman is very stupid to say the least. This is a matter capable of breaking her home.
Many of us who voted for him share her view.
Some dogmatic zombies think one has to be a proverbial fly that follows a dead body to the grave.
The fact that we voted for PMB in 2015 and are yet to see a change says a lot.
But what we must also agree on is that there is no better politician today. I may have no choice but PMB regardless, cos the rest of today's politicians are a waste of space...so corrupt and so dishonest.
Until we the youths come together to identify those amongst some us that can do it, and mentor such persons for leadership.
One might think that she is wailing. But, far from it, that is a voice of reason, a prove that she isn't a sycophant. She could have played to their dictates and concentrate on stealing us dry, but no, she's more concerned about legacy, about posterity and what could have been. That is a wife.
Those evil hands just wanna cut, they don't care whose fingers are caught. Only a dutiful wife will be as concerned. When your husband is changing right before your eyes, becoming someone that you do not recognize, you know that the invisible hands are at work, and you should do anything to save him!
I especially like her motherly instincts. She must have listened to the voices murmuring. It's now Clear who the hands behind the Tinubu brouhaha are.
Mr. President should really watch his back, and especially the company. The wife must have had it up to here to spill it all out like she did on air. And, she must have discussed it with him in the bedroom but got no positive responses.
I read a comment on Sahara Reporters where someone insinuated that those power mongers are never embarrassed. Instead, they will try to set PMB against the wife. In his words, "in the Villa there are no morals, no true friends, only back-stabbers, Power mongers and eye-servicers!" "Abi you think say na 'bridge of flyover' dis [kind] people come look for Abuja so?!"
Nothing could be more true. Those words resonate with me.
Imagine, even Mamman Daura's son was reaching out to BBC in an attempt to stop the broadcast. E be like na ehn entire family go lay mat for Aso.
The scary thing is that they are the closest to the president right now. His true friends remain sidelined.
So,e zombies think we have to follow the dead body to the grave.
The fact that we voted for PMB doesn't mean we do not know why we gave him the mandate.
Buhari will surely bring his wife to order. But your plans of pitching PMB against his loyal loving uncle is DOA.
No one cares abt that, what matters is that she has spoken.
If you like, cage her henceforth, your headache.
It is a shame that you will rather support the misuse of public money while your mother in the village is starving. Aisha Buhari who could have stayed in her comfort zone has chosen to speak on your behalf, exposing those hidden power play which you can never know.
And you come here to scream she is being manipulated.
But of course, I understand your predicament, We cannot all be intelligent.
Stop wailing. Aisha is on covert mode here. Mission: bait to get the real enemies show face fully. Next move is to crush resentment totally. Kyari and Daura are the king'gs men. They leave only when buhari leaves.
No one caged anyone. You guys think you can get buhari move an eye lid using reverse psychology? Try harder, we know your plans and it wont work. My Sai Baba is smarter than y'all.
Daura and kyari are more important to this "change government" than your corrupt master.
You love 'SAi Buhari' more than his wife. What an irony.
where were they during election?
What were their contributions to the manifesto?
Now you see why most of the items in the manifesto have been ignored? Cos these men you mentioned have waved them of.
I hope the men you mentioned have a plan for his reelection too.. Oh yes, rigging.
So Aisha too dey cast aspersions on this administration.. APC and show of shame are like siamese twins..
Whatever it takes, i trust them to deliver come 2019. Call it whatever u like. Just stop wailing and shut up.
You really love Sai Buhari more than his wife. There is nothing I will not see in Nigeria.
Sai Baba for life. Only ignorant wailers say nasty things about him. We all love him and can only get to love him more.
Lalasticlala, now na morning o!
Well said. The hallmark of a great woman. With Aisha nw, i think we've got the Nigerian women covered.
If there's anyone to really give out these strong words, it can only be the first lady.
I shake my head for you because your own zombiism don pass the tipping point. No more hope for you bro.
Fayose's abuses don reset Aisha's brain. Hehehe.
Well, Madam if you want Wailers registration form, you can come and have it.
Even Kids sleep calmly in his arms knowing he's a man with a good heart.
Propaganda of the Highest order. . . Everyone of us know the only First Lady that can talk as loosely as this. . . Her husband 'manhood' will always lives on anyways!
This is explosive! Even Buhari's homefront is in turmoil for his wife to come out and say this. This man has mismanaged the goodwill he once enjoyed. All within less than two years.
All you remaining Yoruba Sai Baba freaks still licking bubu's a$$, hope your eyes are clearing??

Sudreimsätten (norska Sudreimsætten) var en norsk stormansätt, som härstammar från sätesgården Søreim (Sørum) på Romerike, vars namn inte bars av ättens medlemmar.

Vapen
 Blasonering: En vapensköld i silver (vit), senare i guld (gul), med en sjutaggad stjärna.

Historia
Sudreimsätten härstammar från lendmannen Åle Varg, som var gift med en dotter till kung Harald Gille. Han var farfar till Olav Mokk (död 1224), sysselman i Hedmark, som i sin tur var fader till lendmannen Ivar från Skedjuhov (död ca 1240). Hans son, Baron Jon Raud Ivarsson (död 1314) till Sudreim var Fader till Baron Havtore Jonsson (död ca 1320), gift med Håkon V:s dotter Agnes. Deras söner var Jon Havtoresson, som ägde Elingård, och Sigurd Havtoresson av Sudreim.

Jon Havtoresson var fader till Håkon Jonsson, som kom på tal som norsk kung efter Olav Håkonssons död år 1387 och som var förfader till de svenska ätten Roos af Hjelmsäter, liksom dottern Cecilia, gift med värmländske riddaren Ulf Holmgeirsson.

Sigurd Havtoresson gifte sig med Norges rikaste arvinge, Ingeborg Erlingsdatter och kom i besittning av Giske- och Bjarkøygodsen. Deras dotter Agnes, gift med den svenska adelsman Jon Marteinsson (död ca 1400), var mor till Sigurd Jonsson (död 1453) av Sudreim, Giske och Bjarkøy. Han var fader till den sist kände mannen i Norge, Junker Hans Sigurdsson (död 1466). Hans mäktiga gods delades mellan hans kusiner Agnes Alvsdatter (gift med Knut Jönsson av tre Rosor), Gro Alvsdatter (gift med Mads Jakobsson Rømer) och Gudrun Olavsdatter (gift med Erlend Eindrideskon af Losna).

Sätesgårdar inom ätten
 Sudreimsgodset var en godssamling i östra Norge, som vid av slutet av 1400-talet omfattades, förutom av huvudgårdens Sudreim, av 78 gårdar på Romerike, i Odalen och Solør och sex gårdar i Hallingdal. Den sista privata ägaren var Görvel Sparre, som 1599 överlät gården till kungen.
 Sørum var tidigare en sätesgård på Sørum i Lillestrøm kommun, Viken fylke. På medeltiden var gården huvudsätet för Sudreimsätten. Den sista ägaren som kan ha bott på Sørum, är riksföreståndaren Sigurd Jonsson, som från mitten av 1420-talet använde Giske som sin huvudsakliga huvudgård.

Created: 07 Apr 2021 / Categories: Sights of Odessa
In December 1927, an all-Union competition was announced for the project of a zoo in Odessa. Three projects at once were accepted as the basis for the construction of the future zoo. The construction of the zoo along the Arcadian road began in 1929. The city authorities planned to put part of the zoo into operation during 1930. The Yugoklimat Society has already collected a collection of animals for the future zoo. But this project was not implemented either. Only the surviving name of the adjacent street – Zooparkovaya Street – reminds of it.
Despite all the difficulties, G.V. Beizert continued to work tirelessly. In 1933 he was entrusted with the management of the department of the 4th state zoo at the Privoz market. The institution itself belonged to the State Circus, which for several years placed its menagerie in the city garden, and then on the territory of Privoz. At this time in Odessa, by the decision of the Soviet authorities, the 1st Christian cemetery was destroyed. In the late 1930s, Ilyich Park and a zoo appeared on the territory of the former cemetery. After a long stay in the form of a traveling exhibition of animals, in 1938 the zoo acquired a stationary accommodation near "Privoz" on Novoschepny row, where it is located now.
The only archival document confirming the opening of the zoo at a new location on the street. Novoshchepnoy Ryad, 25 became the report of the director of the zoo G. Beizert at a meeting of the executive committee of the Illichivsk District Council of Workers on March 16, 1945, in which he reported that "Odessa Zoo was organized on the territory of Ilyichevsk Park in 1937", and without budgetary allocations worked on a self-supporting basis ".
In 1992, the zoological park received the status of a protected area of national importance and became part of the natural reserve fund of Ukraine. The zoological park has an aquaterrarium. The scientific specialization of the zoo is "Rare and endangered animals of the south of Ukraine".

Purpose: spew hot chunks all over a person, thing, or room.
Synonyms: none
1. spew 1. spew
2. spew <thing> 2. spew statue
3. spew <thing> <qualifier> 3. spew statue red
4. spew <qualifier> <thing> 4. spew red statue
5. spew <n>.<thing> 5. spew 2.statue
Use form one to spew hot chunks.
Use form two when there's no possible ambiguity. In the example, there's only one statue present.
Use form three or four when more information is needed to interpret the command — that is, there's more than one possible target by the same name to which the command could be applied. In the example, there's a blue statue, a red statue, etc.
Use form five when there are many instances of <target> present, and you want to spew all over one of them in particular.
As is typical of most TriadCity commands, Spew searches for <thing> in a specific order, starting with the room you're in, then your worn or wielded equipment, then your inventory. So, if there's a box in the room, and a box in your inventory, the command "spew box" will refer to the one in the room, not your inventory. You'd need to use "spew 2.box" for the latter.
Unlike certain other social commands, Spew cannot be parameterized.
"Since games are closed formal systems, that might mean that games can never be art in that sense. But I don't think so. I think that means that we just need to decide what we want to say with a given game - something big, something complex, something open to interpretation, something where there is no single right answer - and then make sure that when the player interacts with it, she can come to it again and reveal whole new aspects to the challenge presented."

Q: Motorized webcam which can look up, down, left, right with its own application? The title may seem a bit misleading as I was not sure what the term is.
I am looking for a webcam that can turn itself for instance I want it to look to the right or left sides, up or down, so by using the webcam application it will move without the need of me manually moving it.
The other requirement would be for it to have movement sensor.
I currently have a lifecam which I had made a custom motor + hardware to do this for me so with my own piece of software I can freely make it turn left, right, up, down however I've been curious if besides those IP and security cams there is a webcam with such capabilities or what would be the best IP / security cam that fits this requirements?
I guess it would be a motorized webcam or webcam with motorized tripod however some how they need a connection so that the tripod responds to the commands sent to the webcam.

A: I use a Foscam for what you have described.  It's definately not the only option out there but it's one of the cheapest and I believe it fits all your stated requirements.  My only complaints about it is that the resolution is pretty low.  Getting a higher resolution camera that pan's and tilts is usually out of my price range but might be useful to you depending on your specific application.
One thing I do love about this camera is it's easy ability to mount to the ceiling and invert the image, my boss has one as a baby monitor also.  They are good little cameras and surprisingly affordable.

Foscam on Newegg

A: You are looking for a PTZ (pan,tilt, zoom) camera with motion sensing. There are many on market in wide range of price (A search will show you $33 to hundreds of dollars) and functions (IR/night vision, and so on). Primarily these are wireless IP cameras typically for security, but I imagine they would work well as a web cam with some tweaking on focus and placement.
This is one for about $47 US DGGate.com. I have not used it or endorse it, but it may help you on your search and what is available.

I know this isn't food related but I wanted to tell you about the event Luke and I attended Friday night. The event was KEMOPALOOZA which raises money for CAMP KEMO Programs of Palmetto Health Children's Hospital. One of my friends was helping with the event so she told me about it and I immediately knew I wanted to support it. Several of the children who have cancer and blood disorders were there so we were able to meet some of them. They all seemed so happy and appeared to be perfectly healthy. If we hadn't known they were sick, we would never have known by looking at them. They were such an inspiration. Attending an event like this really puts things in perspective. I'm so glad we attended KEMOPALOOZA. The event was also so much fun! There were so many things going on so the evening flew by. They had live and silent auctions, a photo booth and a rum sampling table. Two different bands played and they were both great! Two of the kids got up on stage and danced. I can't even tell you how adorable they were! They truly touched my heart. These are a few pictures from the evening. I wish I had been able to get a picture with those amazing children.
This is one of my best friends and one of my favorite people in the whole world! I'm so glad she told me about KEMOPALOOZA!
If you have an event like this in your community, I highly recommend it. It's for such a great cause!!

Sex difference in the association between solid fuel use and cognitive function in rural China
Haiyan Chen, Li Chen, Guang Hao
BACKGROUND: Whether indoor air pollution from solid fuel use is associated with cognitive function remains unclear.
OBJECTIVE: This study aims to examine the association of solid fuel use with the risk of cognitive impairment in males and females.
METHODS: The data was from the China Health and Retirement Longitudinal Study (CHARLS). Self-reported heating and cooking fuel were categorized as clean fuel (solar, liquefied gas, natural gas, or electricity) and solid fuel (coal, biomass charcoal, wood, or straw). Cognitive function, including orientation and attention, episodic memory, and visuospatial abilities, was assessed using standardized questionnaires.
RESULTS: A total of 7824 individuals were included in our study (aged 57.0 ± 9.3, 46.2% female), with 47.0% and 76.0% used solid fuel for cooking and heating, respectively. There was an interaction between sex and solid fuel use for cooking (P=0.008) for the progress of cognitive impairment. Solid fuel use for cooking was associated with a larger decrease in cognitive function score in females (β=-0.832; 95% CI: -1.043, -0.622; P < 0.001) than in males (β=-0.487; 95% CI: -0.671, -0.302; P < 0.001). The sex difference remained with further adjustment of covariates (β=-0.321; 95% CI: -0.503, -0.138; P=0.001 for males; β=-0.534; 95% CI: -0.745, -0.324; P < 0.001 for females). For heating, the interaction between sex and solid fuel was not statistically significant (P=0.156). After controlling for the covariates, solid fuel use for heating was inversely associated with a 0.321 unit of decrease of cognitive function score (β=-0.321; 95% CI: -0.652, 0.009; P=0.057) in males, and a 0.598 unit of decrease of cognitive function (β=-0.598; 95% CI: -0.978, -0.218; P=0.002) in females.
CONCLUSION: In conclusion, solid fuel use for cooking and heating was significantly associated with a higher risk of cognitive impairment. Furthermore, for the first time, we found that the effect of solid fuel use on cognitive function in females was greater than in males.

Moving On short film review
Directed by: Philip Brocklehurst
Written by: Philip Brocklehurst
Starring: Jonathan Skye-O'Brien, Allie Denison, Roxane Cabassut
Film Review by: Darren Tilby
Lockdown and social distancing laws have made it incredibly difficult for filmmakers to work over the last half a year. But some have persevered and found workarounds to the problems Covid-19 has produced - but to varying success. And "varying success" is certainly the case with Writer/Director Philip Brocklehurst's lockdown-produced, ten-minute-long short film, Moving On. A film which concerns Vincent (Jonathan Skye-O'Brien), a young man, struggling to move on from his relationship with ex-girlfriend, Michelle (Allie Denison). So broken up is he that, after not too much thinking, he deduces he has only two options left: find someone else or take his own life. But what if you can't do either?
A small group of three – all of whom had to film their scenes and send the footage to Brocklehurst to edit – comprises the entirety of the movie's cast. The characters themselves are relatively standard genre concoctions; unremarkable in construction or development. But the screenplay, performances and dialogue (despite having occasional delivery and response problems) are really quite good. And when you factor in the unique circumstances surrounding the film's construction – the actors were stuck in their own homes, miles away from one another and could only be directed through Skype – the fact it turned out as well as it did is impressive.
Moving On truly is both a product and a victim of its time. And nowhere is that more apparent than in its aesthetics. It won't surprise you to hear the camerawork is a little basic; as I said before, the actors recorded their scenes on their own cameras (likely phone cameras), while editing, too, (I believe) was done from home. It's noticeable at times, sure, and at its worst, it's a little disconnecting. But, of course, lockdown presented a considerable stumbling block to overcome, there were always going to be issues left and compromises that had to be made.
On the whole, though, I feel that Brocklehurst and his team have very competently made these difficult circumstances work for them. Performances are solid, the dialogue feels natural, and the pacing is spot on. And at the end of the day, while I don't think Moving On is as good as it should perhaps have been, it's much better than it could easily have ended up.


There's been a little silliness floating around (sadly, in Scientific American, whose article contains at least two factual errors) unscientifically speculating that ATLAS's new results on the Higgs-like particle, from data collected at the Large Hadron Collider [LHC], suggest there are two such particles rather than one. The mass measurement of this particle using the data when it decays to two photons, 126.6±0.3±0.7 GeV/c², is different, by 2.7 standard deviations, from the mass measurement obtained from its decays to two lepton/anti-lepton pairs, 123.5±0.9+0.4-0.2 GeV/c². So… huh… gee… maybe there are two Higgs-like particles, a lighter one which rarely decays to two photons and a heavier one which rarely decays to two lepton/anti-lepton pairs?
Take a deep breath. For not only would the two types of particles somehow have to be magically and implausibly arranged to mimic, at first glance and to a rough extent, a single Standard Model Higgs particle (the simplest possible type of Higgs particle), there's another experiment, which unfortunately the writer of the Scientific American article neglected to consult.
ATLAS's mass measurement from the events with two lepton/anti-lepton pairs also disagrees with CMS's mass measurement obtained from the same type of events: 126.2±0.6±0.2 GeV/c². Two similar experimental detectors, same measurement, moderate disagreement. Nature is nature; there's no way that ATLAS can be making one type of particle all the time, while CMS is making a different one all the time. So there is no evidence here, taking ATLAS and CMS together, favoring the existence of a separate particle with a mass of about 123.5 GeV/c² that decays to two lepton/anti-lepton pairs.
What is behind these discrepancies, then? ATLAS and CMS each have scarcely a dozen of these two lepton/anti-lepton events, and their extraction of the Higgs particle's mass from each event is somewhat uncertain, which is why many events are required for a good mass measurement. When you still have small amounts of data, funny statistical fluctuations will often occur. We've seen this before; back in 1989, when the Stanford Linear Collider (SLC) produced its first few Z particles at the Stanford Linear Accelerator Center, the plot of the Z particle's mass gave a double resonance peak, instead of the single peak that was expected. A brief moment of speculation occurred, but with more data the anticipated single peak structure emerged. I've heard at least one other similar story from an earlier decade. In fact ATLAS and CMS had a 2 GeV mass discrepancy when the first Higgs hints came in; that was just an effect of statistics. Combine a fluctuation of this form with a minor detector calibration problem, and you'll get discrepancies like this.
Multiple types of Higgs particles are certainly possible; people have considered this scenario for decades, and I've written about it here, for instance. Efforts to search for a second type of Higgs particle have been going on since the discovery of the first one. But let's not manufacture one out of thin air by looking selectively at the data; that's not how reliable science gets done.

I'd be interested to know how the ATLAS result was presented to the Scientific media community. Was it given in a matter-of-fact way which required, or even enticed the writer to conclude the possibility of a second Higgs boson?
Or was it given with a caveat that, 'we don't suspect for one moment that this is a new boson' ?
I agree with the anonymous comment below: the result was presented in a fully matter-of-fact fashion, and with the utmost professionalism.
I'm not sure where your "feeling that ATLAS is a little bit too quick to release its results to the media and to journals". I don't see any evidence of that.
ATLAS held the result back for a month looking for systematic errors. Eventually they decided to go ahead and publish with an extensive analysis of how significant the discrepancy between the mass peaks is. The answer is that the peaks are reasonably different, but not inconsistent with a statistical fluctuation. This was handled with the highest grade of responsibility and professionalism.
Thank you Anonymous. Then this really follows on from Prof. Strassler's previous post about how to help the media avoid running sensationalised stories based on a fraction of a press release. I'm sure if some science journalist read your reply, the words "the peaks are reasonably different" would be lit up in red letters like some synesthetic hallucination.
Maybe it is wise to hold off giving such results until the point where we know they are different peaks or the peaks have converged with additional data. In its current form, is it really a result, or just a result of half-a-job done? We all know peaks come and go. Why rush to report them?
PS. I'm certainly not singling out ATLAS. This happens in all fields of science. Just read the BMJ for copious examples!
In this case, (2) won the day, which scientifically is best, in my view. Politically it does cause some problems, and it is unfortunate those problems came out of Scientific American.
I should also emphasize that ATLAS has not made a press release about this. They are downplaying this discrepancy, as they should. Their presentation was made as part of a whole morning of talks by all the LHC experiments; it didn't have any special billing. As far as I can tell, these speculations and resulting hype were generated entirely by others.
Looking at the situation from an engineer´s point of view, it seems to me rather normal that a new experiment with two new measurement devices gives slightly different readings on both devices; in fact, it would be very suprising if both detectors yielded the same value already in the first place. Calibrating the detectors is a difficult task, and there is always the possibility that such complex devices show some sort of systematic error that was not taken account for in the design.
I think it was correct to finally publish the measurements, without any hype. The teams running the operations at LHC need to know about the difference as this may indicate that further calibration is necessary, which is a normal procedure with such experiments.
This particular difference is only at one device, ATLAS. Still, everything you said applies to differences between ATLAS and CMS.
Well, that's not entirely true, Carl. The measurement of the energies of photons, of electrons and of muons use different combinations of the sub-devices that make up ATLAS. And for that reason, separate calibrations are required for these particles. So in an important sense Markus was right.
It sounds like there are several measurements that are all very close to each other around 126 GeV and one that is pretty far from the mark at 123.5 GeV that could be off due to an experimental error, a statistical fluke (in a quite small sample) or a bit of both. As the OPERA debacle revealed, it can take several months of intense investigation to get to the bottom of a subtle apparatus problem (although it never looks subtle once you find it).
The point that it can't be two Higgs because all of the measurements would have seen two is well taken.
If I were a betting man, I'd bet that the 123.5 GeV data point was in error, and make predictions on the assumption that the 126 GeV value was correct rather than including that data point in the overall estimate.
What is an electron so stable?
What is most upsetting is that it is always the scientists, who have done nothing wrong but honestly reported or talked about their results (maybe even at a scientific conference that was NOT intended for a wider public in some cases?), who get the blame from the public, if science journalists overdo it, are not careful enough, or even make up or distort things to sell a better story.
I do not see any problem in Scientific American's article, no silliness about it. I do see a big under current about this Higgs story.
a. In the July 2012 announcement, it did not claim that the new particle is a Higgs.
b. On 16 October 2012, in the article "The Inner Life of Quarks, by Don Lincoln, Scientific American", it discussed a long dead idea of preons.
c. In the 13 November 2012 reports (almost 5 months after the initial report), CERN did not confirm that the new particle is a Higgs. At the same time, SUSY received a deadly blow by the LHCb data.
d. In the 13 December 2012 report, Atlas reported the problems in the Higgs data.
e. On December 14, 2012, in the article "Have Scientists Found Two Different Higgs Bosons?, by Michael Moyer, Scientific American)", it hints that the Higgs is in trouble.
The above is not a good trend for Higgs. Instead of being silliness, Scientific American is seemingly knows something which we do not know about. Yet, we do (at least, should) know the simple physics fact.
i. SUSY is the extension of Higgs. If SUSY is out, the Higgs alone cannot survive.
ii. Whatever SUSY is, it must have a tail sitting right around the weak-scale. If not, it is disjointed from "this" universe and cannot be a part of "this" physics. Let it be the physics of the "other" universe.
