TRANSFORMING 3D VIDEO CONTENT TO MATCH VIEWER POSITION

摘要

Systems and methods for transforming 3D video content to match a viewer's position to provide a means to make constrained-viewpoint 3D video broadcasts more independent of viewer position. The 3D video display on a television is enhanced by taking 3D video that is coded assuming one particular viewer viewpoint, sensing the viewer's actual position with respect to the display screen, and transforming the video images as appropriate for the actual position. The process provided herein is preferably implemented using information embedded in an MPEG2 3D video stream or similar scheme to shortcut the computationally intense portions of identifying object depth that is necessary for the transformation to be performed.
