Abstract
A system and method for stereoscopic video teleconferencing provides an immersive virtual meeting experience. Each participant is surrounded by at least two video cameras. The system senses the position of each of the participants and uses this information to select, for each participant, camera pairs to capture a stereo pair of video images of each of the other participants. The system is adapted to isolate the image of each participant from the background. The system transforms the stereo pair images to adjust the perspective for the interocular spacing of each participant. The processed stereo pairs of video images are transmitted to the respective participants. For each participant, the system assembles a stereo video display image of a virtual meeting room, combining the stereo pair images of each of the other participants appropriately sized and positioned. Three-dimensional (3D) virtual objects can also be displayed and manipulated by participants.
