Abstract: Stereo vision system is a vital part of the anthropomorphic robot. To satisfy the special requirement of the stereo vision system, a multi-thread video capture system based on DirectShow is proposed. The system is good development platform, which is simple and can be used to synchronically capture video streams of two same type of USB cameras.
