A conventional 3D image transmission system is made of a stereo camera and a stereo viewer, so that a user is able to see a scene stereoscopically. However, it does not allow the user an operation to change his/her viewpoint arbitrarily, because the position of camera is fixed.
This thesis proposes a new 3D transmission method that realizes dynamic change of the viewpoint on user's demand. This method utilize two different kinds of images, 1) ``range images'' acquired by a real-time range finding sensor, and 2) ``texture images'' taken by a CCD camera. These two types of images are transmitted via a digital network. Then a graphic workstation at receiver side reconstructs a 3D view from transmit images by using texture mapping CG.
Furthermore, in order to compress the transmission data, dynamic resolution switching of texture images is introduced. Three types of switching criteria are experimented. A prototype 3D image transmission system with this image compression technology is developed.
