As a key technology for stereo vision, stereo matching has become a hot research topic in the field of ma-chine vision. In order to improve the performance of the stereo matching method based on dynamic programming, a state space model was built to analyze three main influencing factors, including disparity search range, the size of clustering window, and the number of control points. The improved scheme is composed of two parts: the control points are computed at a low resolution level image of the Gauss tower, and the shape of the window is adjusted ac-cording to the position of control points at two sides. The experimental results show that the improved method can quickly finish the stereo matching process while guaranteeing the quality of the disparity image.
