with high resolution projectors in a geometrical alignment which ensures a homogeneous projection of the individual image areas each separate image area overlaps with the adjacent areas to allow pixel exact overlay in the transient areas by using digital image warping and blending to create a seamless overall projection an auto alignment system can be integrated to take care of either initial projection setup as well ongoing adjustments to guarantee a fully automatic calibration of the entire projection this is realized with a number of network cameras which observe the full projection area the camera system is also used to capture areas inside the entire projection which need to be digitally black masked e g for eventual movable platforms such as the loading and unloading platform of fig5 8 in particular the projectors are arranged to project motion picture on the entire projection screen the projection screen surrounds the first and second audience platforms 8 and 9 so that the screen extends over an angle of 360 u00b0 when seen in a horizontal plane see fig3 further the dome portion 2 and the extension portion 3 of the projections screen 1 are arranged and realized such that they together provide a projection surface extending over an angle u03b1 of more than 180 u00b0 measured in a vertical plane from a center of the dome in fig2 the first and second audience platforms 8 and 9 are shown in an elevated position accordingly the hydraulic cylinders 14 are shown in an extended position in fig3 the circular row of seats 18 is illustrated further it is shown that the tower structure 11 has a rectangular cross section further an access path 19 is illustrated via which guests can access the first and second loading and unloading platforms 6.
