Using stereo camera system to realize realistic video avatar in virtual environment

With the appearance of different kinds of virtual environment systems, the technology of realistic video avatar is becoming a hotspot of research. Our target is to create a realistic video avatar with less hardware investment and limited computation. In this paper, we introduce a method that combines a single stereo camera and 3D head model to engender a realistic video avatar. To engender the video avatar's most important part - the face part - we use the 2D image and depth map, which is generated by the stereo camera. To engender the other parts of the 3D head model, we map the head's texture to the 3D head model.
