- W2088097679 abstract "Versatile three-dimensional (3D) image data as in the form of I(X,Y,Z) defined in the camera coordinate system areacquired from sets of color image and depth image, which are simultaneously captured at a video frame rate by a 3Dcamera named Axi-Vision camera. The X and Y coordinates are calculated from the image coordinates (x, y) on theimage plane of CCD based on the perspective projection theory. The Z coordinate can be obtained for each pixel of thecolor image directly from the depth image without any complex processing. Thus, the 3D image data of objects, I(X,Y,Z),is obtained from the relation between the camera coordinate and the image coordinate systems. A stereoscopic videoimage display is demonstrated using the 3D image data using an integral photography (IP) system, which combines a 4-inch VGA liquid crystal color display panel and a pinhole array. Aliasing, an issue from mismatch of image qualitiesbetween the 3D image data and the IP system, is effectively suppressed by pre-processing the color Axi-Vision imagedata using a two-dimensional lowpass filter, which is designed based on analyses of the maximum spatial frequency ofthe 3D image transformed appropriate for the LCD size and the Nyquist spatial frequency of the IP system." @default.
