The present disclosure relates to the security inspection field, and in particular, to an image data processing device and a security inspection system based on virtual reality (VR) or augmented reality (AR).
With rapid development of container transportation business, more and more goods are contained and transported via containers. Due to the hidden nature of the goods in the container, it brings opportunities to shippers to conceal dangerous goods and smuggled goods. Although inspection means like X-ray transmission systems have brought great convenience to safe transportation of the containers, image viewers who take charge of watching monitors to obtain goods information only by their experience have a great burden, and thus are easily tired. On the other hand, there is still a certain percentage of the containers required for unpacking inspection in actual practices, but there are many difficulties in the unpacking inspection of the containers. For example, the containers are often used for transporting large objects, and carrying them out of the containers is complex and dangerous. In another example, the goods in the containers are arranged closely, and there are difficulties in reassembling them after their unpacking inspection. In yet another example, procedures of the unpacking inspection are complex and time-consuming, extending the shipping time. In addition, a direct on-site unpacking inspection for the containers in which the dangerous goods are concealed also threatens personal safety of inspectors.
Objects of the present disclosure consist, at least in part, in providing a method, a device and a security system for image data processing based on virtual reality (VR) or augmented reality (AR).
According to an aspect of the present disclosure, there is provided an image data processing method, including: reconstructing, based on three-dimensional (3D) scanned data of a containing apparatus in which objects are contained, a 3D image of the containing apparatus and the objects contained in the containing apparatus; stereoscopically displaying the reconstructed 3D image; determining manipulation information for at least one of the objects in the containing apparatus based on positioning information and action information of a user; re-reconstructing at least a 3D image of the at least one object based on the determined manipulation information; and presenting the at least one re-reconstructed object on the displayed 3D image.
According to another aspect of the present disclosure, there is provided an image data processing device, including: a communication interface, configured to receive 3D scanned data of a containing apparatus in which objects are contained; and a processor, configured to reconstruct, based on the received 3D scanned data, a 3D image of the containing apparatus and the objects contained in the containing apparatus for display; wherein the communication interface is further configured to receive positioning information and action information of a user, and wherein the processor is further configured to determine manipulation information for at least one of the objects in the containing apparatus based on the received positioning information and action information, and re-reconstruct at least a 3D image of the at least one object based on the determined manipulation information.
According to yet another aspect of the present disclosure, there is provided a security inspection system is provided, including: a 3D scanning device, configured to 3D scan a containing apparatus in which objects are contained to generate 3D scanned data; a location tracking device, configured to position a location of a user for providing positioning information of the user; a motion tracking device, configured to determine a motion of the user for providing action information of the user; an image data processing device as previously described; and a stereoscopic display, configured to display a reconstructed 3D image.
According to yet another aspect of the present disclosure, a computer readable recording medium having executable instructions stored thereon, which when executed by one or more processors, cause the one or more processors to perform operations of: reconstructing, based on 3D scanned data of a containing apparatus in which objects are contained, a 3D image of the containing apparatus and the objects contained in the containing apparatus; stereoscopically displaying the reconstructed 3D images; determining manipulation information for at least one of the objects in the containing apparatus based on positioning information and action information of a user; re-reconstructing at least a 3D image of the at least one object based on the determined manipulation information; and presenting the at least one re-reconstructed object on the displayed 3D image.
For example, the 3D scanned data include at least one of X-ray Computerized Tomography (X-CT) scanned data and multi-view X-ray scanned data. These data may be obtained by, for example, a 3D scanning device, such as an X-CT scanning device or a multi-view X-ray scanning device.
At least one of structural and material properties of the at least one object may be determined based on the 3D scanned data. The determined at least one of the structural and material properties of the at least one object may be displayed around the at least one object.
The display for displaying the 3D image and various other information may be a stereoscopic display, such as a stereoscopic display of a helmet type, a glasses type, a desktop type, a projection type, a hand-held type or an auto-stereoscopic display type.
Feedback information may be determined based on the manipulation information and/or the determined at least one of the structural and material properties. The user may be provided with force/tactile feedback based on the feedback information. For example, the user may be provided with the force/tactile feedback by a force/tactile feedback device worn by the user.
The scanning device may be controlled to further scan an area where the at least one object is located based on the determined manipulation information.
According to embodiments of the present disclosure, the (3D) image of articles within the containing apparatus (e.g., the container) may be generated by the 3D scanning device (e.g., the X-CT or the multi-view X-ray scanning device). A VR or AR space may be created by stereoscopically displaying the generated image. An inspector may be equipped with a VR or AR enabled auxiliary device to enter the VR or AR space, and may rummage and inspect suspected areas. The inspector's actions may be reflected into the virtual space in real time, and the rummage inspection process may be displayed simultaneously. Thus, the inspector can have a sense of reality of coming to the inspection spot in person by interaction with the articles within the containing apparatus in a digitalized environment using the VR or AR enabled device. Compared with the unpacking inspection on site, such a simulated inspection way vividly and simply shows the conditions of the goods in the container and the process of unpacking inspection, saving manpower, material resources and time consumed by the inspection and improving efficiency and security of operations of the container inspection.

FIG. 1 is a block diagram schematically showing a security inspection system according to an embodiment of the present disclosure.
As shown in FIG. 1, a security inspection system 100 according to this embodiment may include an image data processing device 110, a three dimensional (3D) scanning device 120 and a stereoscopic display device 160. Such a security inspection system 100 may be applied to places, such as stations, airports, customs etc., where articles need to be inspected to prevent entry of contraband.
The 3D scanning device 120 may perform 3D scanning on a target, e.g., a containing apparatus (e.g., a container) 200 in which objects are contained, so as to generate 3D scanned data. Here, the "3D scanned data" refers to data, based on which a 3D profile of the scanned target can be reconstructed to obtain a 3D image of the scanned target. For example, the 3D scanning device 120 may include an X-ray Computerized Tomography (X-CT) scanning device, a multi-view X-ray scanning device, etc.
In an example, a security inspection channel may be arranged, and a radiation source (e.g., an X-ray generator) and corresponding detector(s) may be deployed around the security inspection channel. The target to be scanned may pass through the security inspection channel (e.g., by a transfer device, a transport vehicle, etc.). When the target passes through the security inspection channel, radiation emitted by the radiation source may irradiate the target, and transmitted (and/or scattered) by the target to be detected by the detector(s). According to the detected radiation, information inside the target may be learned. For example, in the scanning device, such as the X-CT scanning device or the multi-view X-ray scanning device, a cross-section of the target may be reconstructed according to the detected radiation, and the 3D profile of the target may be generated based on a plurality of such reconstructed cross-sections.
In addition, the dual-energy scanning technology may be used. For example, the target may be scanned using high-energy and low-energy X-rays. Using the dual-energy scanning technology, material properties, such as an equivalent atomic coefficient, density, etc., of the target may be obtained in a better way. However, the dual-energy scanning is not definitely necessary, e.g., in a case that single-energy scanning is sufficient to determine desired material information.
A speed of the scanning may be controlled to get a certain amount of scanned data. The amount of the scanned data is sufficient, on one hand, to generate a clear image, and on the other hand, may not be too much, in order to reduce storage and processing burdens.
Here, a containing apparatus for accommodating the objects, such as a container, may be described as an example, but the present disclosure is not limited to this. The technology of the present disclosure is suitable for various security inspection scenarios.
The image data processing device 110 may reconstruct a 3D image of the target, e.g., the container and the object(s) accommodated therein, based on the 3D scanned data generated by the 3D scanning apparatus 120. For example, the image data processing device 110 may detect edges of each object from the 3D scanned data by using edge detection technology, and may match the edges of the same object at different viewing angles, so as to reconstruct the cross-section of the object. By connecting a plurality of cross-sections of the same object (and possibly interpolating between the cross-sections), the 3D profile of the object may be obtained. On the other hand, the material properties, such as the equivalent atomic coefficient, the density value etc., of the object may be calculated based on the reconstructed cross-section.
The stereoscopic display device 160 may stereoscopically display the 3D image reconstructed by the image data processing device 110. In this way, an image space, i.e., a virtual reality (VR) or augmented reality (AR) space 400 (hereinafter referred to as "a virtual space") is created. Such a virtual space does not necessarily be a physical space in the real world, but may be a space that can be perceived by the user 300's vision. For example, the eyes of the user 300 may receive light signals from the display device, so as to perceive as if he was exposed to a certain space (in this example, the internal space of the target to be inspected).
The stereoscopic display device 160 for displaying the 3D image (in real time) may be of a helmet type, a glasses type, a desktop type, a projection type, a hand-held type or an auto-stereoscopic display type etc. For example, in a case of a single user, the user may wear the helmet-type or glasses-type display device; while in a case of multiple users, the desktop-type, the projection-type, the hand-held type or the auto-stereoscopic display-type display device may be used.
According to an embodiment of the present disclosure, it may be determined whether there is contraband such as explosive, weapons or the like based on the material properties, such as the equivalent atomic number and the density value. For example, the atomic numbers and the densities in the plurality of cross-sections may be averaged. If the resultant average value falls within a contraband area in a contraband database, it may be determined that there is contraband; if the average value falls into other areas than the contraband area, it may be determined as a safety product. Objects that are determined to be contraband may be highlighted to alert the user.
According to an embodiment of the present disclosure, the detected object may be compared with a list of items (e.g., a declaration of customs) based on the structure (e.g., 3D profile) and/or material properties of the object. If the detected object matches an object listed in the list of items, relevant information (e.g., an item name, a manufacturer, etc.) in the list of items may be displayed (e.g., in a form of text) around the corresponding object. If there is no item in the list of items matched with some detected object, the user is alerted.
In addition, the determined structural and/or material properties may also be displayed (e.g., in the form of text) around the respective objects for facilitating the user to view.
The security inspection system 100 may further include various sensing devices, such as a location tracking device 130 and a motion tracking device 140, for sensing location and motion of the user, in order to determine which one of the objects and how the user desires to manipulate. These sensing devices may be wearable, so as to be worn by the user on his/her body; or may be provided separately from the user.
The location tracking device 130 may position the location of the user to provide positioning information of the user. The image data processing device 110 may map the positioning information of the user determined by the location tracking device 130 into the image space or the virtual space. For example, an initial location of the user may be mapped to an entrance of the container, and the location of the user in the virtual space may be changed accordingly based on the user's movement determined by the positioning information. For example, when it is determined based on the positioning information that the user moves leftward/rightward/forward/backward by a certain distance, the location of the user in the virtual space may be moved leftward/rightward/forward/backward relative to the initial location by a corresponding distance, which may be identical with an actual moving distance of the user, or scaled by a certain factor.
For example, the location tracking device 130 may include a Global Positioning System (GPS) device carried by the user, an ultrasound positioning device carried by the user and co-located with an ultrasonic transceiver arranged around the user, or a video device. In a case of the video device, the user's movement may be determined by image recognition.
The location tracking device 130 may include a plurality of location sensors provided at different parts of the user's body. The image data processing device 110 may respectively map the different parts of the user into the virtual space according to the sensed data of the plurality of location sensors, so as to more accurately locate the location of the user in the virtual space.
The motion tracking device 140 may determine the user's motion in order to provide action information of the user. For example, the motion tracking device 140 may track certain key points (e.g., joints, hands, etc.) of the user, and capture motion data of the user. For example, the motion tracking device 140 may include data clothing. The image data processing device 110 may map these motion data onto a (pre-stored) human body model, and may generate a continuous process of body motion by motion control.
The image data processing apparatus 110 may determine manipulation information for at least one of the objects based on the positioning information and the action information of the user. For example, when it is determined based on the positioning information that the user is located besides some object, and it is determined based on the action information that the user makes an action, such as moving, turning over, etc., the image data processing device 110 may determine the manipulation information for the object (translation/rotation, a translation distance, a rotation angle, etc.). The translation distance and the rotation angle may be determined according to a magnitude of the action.
When the user manipulates the object in the virtual space, the display in the virtual space may be updated accordingly. For example, the image data processing apparatus 110 may at least partially reconstruct the 3D image (e.g., reconstructing a 3D image of the manipulated object, and, optionally, reconstructing a 3D image of a region around the manipulated object, and, of course, reconstructing the entire 3D image), based on the manipulation information. For example, when the manipulation information indicates a translation manipulation, the 3D image of the object may be reconstructed to a location to which the object is translated, and the object may be removed from its original location. In another example, when the manipulation information indicates a rotation manipulation, the object is reconstructed from different angles of view depending on its rotating angle. As such, it appears to the user as if he is really manipulating the object.
As described above, the user may operate on the object which is alerted to possibly be contraband, in order to inspect the object more carefully. After an object is determined to be a manipulation target, the structural and/or material properties of the object may be displayed around the object for user's reference.
According to an embodiment of the present disclosure, after an object is determined to be a manipulation target, the image data processing device 110 may send an instruction to the 3D scanning device 120 to further scan the area where the object is located, e.g., to scan the area with a higher intensity and/or at denser scanning intervals, for clearer details. The image data processing device 110 may re-reconstruct the image of the area based on re-scanned data, and update the display of the area.
According to an embodiment of the present disclosure, it is also possible to provide a perceptive feedback to the user in order to provide the user with more realistic feeling. To this end, the security inspection system 100 may also include a force/tactile feedback device 150. The force/ tactile feedback device 150 may reflect physical characteristics, such as texture, material, and state (such as a liquid state, a solid state, a gel state, etc.), and movement changes of the object in the virtual space to the user through tactile sensing. For example, the force/tactile feedback device 150 may give a certain stimulus to the user, so that the user may obtain some sense of perception. For example, the force/tactile feedback device 150 may include data glove(s), within which some contacts that may be vibrated are mounted to simulate tactile sensation.
The image data processing device 110 may determine feedback information based at least in part on the manipulation information and/or at least one of the structural and material properties of the object. For example, when the user is manipulating the object, he may feel some reaction force. Therefore, the force received by the user may be determined based on the manipulation information, and the user may be given the feeling of such a reaction force by the force/tactile feedback device 150. For example, when the user is moving an object with both his hands, he may feel a weight of the object. The force/tactile feedback device 150 may enable the user to have such a feeling by applying a downward force to the user. The amount of the force applied may be determined based on a volume, a density value or the like of the object. In addition, there may be some concave-convex or texture on a surface of the object. Such concave-convex or texture on the surface may be determined according to the structural/material properties. The force/tactile feedback device 150 may give the user a feeling of concave-convex or texture by adjusting the contacts. In addition, the different material of the object will give different tactile sensations, such as smooth or rough. Such a tactile sensation may be given to the user by the force/tactile feedback device 150.
On the other hand, the force/tactile feedback device 150 may also analyze the user's motion parameters, such as a direction, a velocity, an acceleration, etc. For example, a position sensor, a bending sensor and a distortion sensor etc. may be installed at fingers of the data glove, and a curvature sensor, a radian sensor etc. may be installed at a palm portion of the data glove. With such a data glove, motion data, such as locations, orientations of hands and joints, finger's states (close together or open, upturned or bent down), may be determined. The image data processing device 110 may determine manipulations, such as fetching, moving, assembling, or controlling, on the object in the virtual space, based on these motion data (in conjunction with the data of the motion tracking device 140). This motion-sensing function may be incorporated into the motion tracking device 140. However, e.g., in the case of the data glove, since both the motion sensing and tactile feedback are provided in the hand part, they are integrated in the same device, i.e., the data glove.
In the above examples, the image data processing device 110 in a centralized form has been described, but the present disclosure is not limited thereto. For example, the image data processing device 110 may be implemented in a distributed manner, including a plurality of processing devices connected by wired and/or wireless links. These processing devices cooperate to accomplish the functions of the image data processing device 110 as described above. In one example, the image data processing device 110 may include an image processor for image reconstruction and a data processing device for processing other information (e.g., sensor information, manipulation information, feedback information, etc.). The image processor may undertake the image reconstruction with a heavier load, and may have a higher configuration for a faster processing speed (e.g., updating the 3D image in real time to provide the user with a realistic feeling). On the other hand, the data processing device is responsible for other information processing with a lighter load, and may have a lower configuration, e.g., implemented by a general-purpose computing platform, such as a personal computer (PC), a notebook computer, a tablet computer etc.
FIG. 2 is a flowchart schematically illustrating an image data processing method according to an embodiment of the present disclosure.
As shown in FIG. 2, the image data processing method 1000 according to this embodiment includes generating a 3D image based on 3D scanned data at operation 1100. As described above, the 3D scanned data may be obtained by scanning an inspected target (e.g., a containing apparatus which contains objects) by a 3D scanning device at operation 2100.
At operation 1200, the generated 3D image may be displayed stereoscopically, so as to create an image space, i.e., a virtual space (VR or AR space). As described above, the structural and/or the material properties of the objects may be determined based on the 3D scanned data, and the determined structural and/or material properties may be displayed around the respective objects at operation 1600.
At operation 1300, manipulation information for at least one of the objects may be determined based on positioning information and action information of the user. For example, the positioning information and the action information of the user may be determined by a location tracking device, a motion tracking device (and optionally, a force/tactile feedback device) at operation 3100. As described above, the 3D scanning device may be instructed based on the manipulation information to further scan an area around the manipulated object.
At operation 1400, the 3D image may be re-generated at least partially based on the determined manipulation information. As described above, the manipulated object may be reconstructed, the area around the object may be reconstructed, or even the entire 3D image may be reconstructed. For example, a location, an orientation, etc. of the object in the virtual space may be changed according to the user's manipulation.
At operation 1500, the 3D image may be updated so as to present the re-generated portion.

Injectable fillers are used to plump up wrinkles or creases that develop as the face ages. This produces smoother, more youthful appearing skin. Fillers may also be used to add fullness to the lips and cheeks. The results may be temporary and, depending on the filler used, may need to be repeated every 6 months to 2 years.
Dr. Lichten offers a variety of facial injection techniques for patients who wish to reduce the appearance of fine lines and/or to enhance their lips. Fine lines around the nose, mouth, lips, and in the cheeks and chin are gently smoothed with one of the products in the JUVÉDERM® Family of Injectable Fillers or Restylane®.
Dr. Lichten has experience with a wide range of dermal filler products, including, JUVÉDERM, Juvéderm Voluma, Restylane and Sculptra™. Facial fillers plump up the lines in your face and smooth out wrinkles by restoring lost volume. Fillers also can be used to add fullness to the lips and cheeks. Fillers work differently than BOTOX® Cosmetic, because rather than relaxing the muscles like BOTOX, the fillers actually increase volume beneath the skin. As a result, you will be able to see the effects of facial fillers immediately. Dr. Lichten offers a wide variety of facial injection techniques depending upon your specific needs. Injectable products can be used in conjunction with cosmetic procedures such as face lift surgery in Columbus, Ohio or other medical spa services like chemical peels and laser skin rejuvenation, and Fraxel re:pair laser resurfacing.
JUVÉDERM Ultra Plus and Restylane are similar products made by different manufacturers. Both are made from hyaluronic acid. There are subtle distinctions between the two that will affect which product Dr. Lichten believes is the better choice for each individual. These fillers are primarily used to smooth the lines between the nose and the corners of the mouth (the "nasolabial folds"), which are sometimes called "parentheses." These fillers can be used to create fuller lips and minimize the tiny lines over the mouth which can cause lipstick bleed.
Juvéderm Vollure is the latest product in the Juvéderm family of fillers. It uses Juvéderm's patented vycross technology and creates a more subtle correction. This formulation allows Dr. Lichten greater control and finesse to correct more superficial wrinkles in the nasolabial folds and elsewhere in the face.
Juvéderm Ultra, Juvéderm Vollure and Restylane all contain lidocaine, which numbs the area during the injection. The lidocaine does not change the effectiveness of the products, but many patients feel that the lidocaine adds a level of comfort to the procedure.

Juvéderm Voluma is used to restore lost volume to the apples of the cheeks. As we age, the face tends to flatten out and Dr. Lichten uses Voluma to re-create the curve of the cheekbone and add fullness to the face. In our experience with the product, Voluma tends to last longer than other fillers – around 18 months to two years. For more information on Juvéderm Voluma XC, click here.
For patients who want to restore lost volume in their lips but create a natural look, Juvéderm Volbella, Juvéderm Ultra Plus and Restylane Silk are great options. These products allow Dr. Lichten to have greater control and finesse to create a beautiful, natural lip. For more information on lip enhancement, click here.
Sculptra is a longer lasting option for filling out the lower cheek area. Made from poly-l-lactic acid, Sculptra has been used widely for restoration and correction of facial fat loss and atrophy. Sculptra injections may last for 2 years or more. Dr. Lichten has found that Sculptra is effective in filling out lost volume in the cheeks, or the "hollowed-out" appearance that comes from aging or weight loss. Sculptra is valuable for patients with volume loss all over their faces including the temples, cheeks and around the mouth. For more information on Sculptra, click here.
Collagen is the fibrous protein that is a major component of the skin. It gives the skin its structure and has been used for decades to replenish the skin's volume loss. Collagen can smooth out facial lines, wrinkles, and scars as well as to plump pouty lips. The effects of collagen injections usually last from 2 to 3 months and can be repeated as necessary. Skin testing may be necessary as allergic reactions are possible. Although collagen largely has been replaced with injectable fillers like Juvéderm and Restylane, it is still used for some people.
Dr. Lichten can take fat from one area of a patient's body, usually the buttocks, thigh, or abdomen, and use it to fill another. Fat injections can be used to fill in wrinkles and lines, create contours in the face, enhance lips, and fill in scars. While usually long lasting, fat injections may not be permanent. Fat injections are done as a surgical procedure in conjunction with liposuction. For more information on Liposuction, click here.


SANTA CLARA, Calif. (AP) San Francisco 49ers linebacker Malcolm Smith suffered a torn pectoral muscle during Saturday's open practice at Levi's Stadium, putting in doubt the status of one of the team's most coveted offseason additions.
The team announced the injury Saturday night but had yet to make a roster move, and with not practicing again until Monday it provided a little bit of time for evaluation.
Smith, 28, left the field during full-team drills after working with the starters throughout training camp next to All-Pro NaVorro Bowman in the new-look defense.
''We think it was his chest area. Don't know for sure. But that's what it looked like,'' 49ers coach Kyle Shanahan said earlier in the day.
Smith, the MVP of Seattle's Super Bowl-winning team in the 2013 season, was brought in by San Francisco on a five-year contract in March. He rejoined new coordinator Robert Saleh, who was an assistant on the Seahawks' title team. Smith was expected to help transition to the new 4-3 scheme that's similar to what he ran with Seattle.
''That'd be a big one for us, just because we've been getting so many reps together, jelling together and really talking about what the offense is trying to do to us throughout these OTAs and in training camp,'' Bowman said of potentially losing Smith.
If Smith is sidelined, it may expedite first-round pick Reuben Foster's insertion into the starting lineup. Foster, 23, fell to the 31st selection in the NFL draft after he was widely expected to be a top-10 pick. The 49ers traded back into the first round to take Foster and said he was one of the top-three players on their draft board.
The Alabama alum won the Butkus Award last season and would be Smith's likely replacement. He ascended to working with the second string this week during team drills after being limited in the offseason program while recovering from shoulder surgery.
Veteran Ray-Ray Armstrong is also an option. He replaced Smith in the starting lineup Saturday as the weak-side inside linebacker during the full-team session.
The 49ers might also be without second-year guard Joshua Garnett, who sustained a knee injury that could require surgery.
Garnett, a first-round pick in 2016, was competing with Zane Beadles for the starting left guard spot after starting 11 games at right guard as rookie.
