Stereo matching is an important part in stereo vision. For traditional matching algorithm having difficulties to satisfy both accuracy and speed, a novel local stereo matching algorithm is presented in this paper. Firstly, an initial disparity estimation is obtained by using dynamic window of region growing algorithm based on color constraint for matching. On the other side, a simple but efficient way is proposed to further improve matching accuracy without adding additional computational work. Experimental results show that the algorithm we presented can not only get a more accurate disparity map at repetitive areas and depth discontinuities but also meet the need of real-time.
