Human-computer interaction system based on binocular stereo vision

Binocular stereo vision is an important aspect in computer vision field. In this paper, it is made a systematic research, which is the system of human-computer interaction based on bincular stereo vision. In order to improve the anti-interference performance, the hardware system worked in the condition of near infrared; to inhance the real time operation, the level of difficulty with stereo matching algorithm is simplified through special hardware design; based on the ICP algorithm for tracking tools, the flexibility and convenience of system are increasingly. The application in surgical navigation system is discussed. In the prototype system, how to unified virtual coordinates and real coordinates has been presented; the problem on how to tracking patient undergoing in real-time is solved. The result has higher precision and practicability, which provide a good platform for virtual reality.
