Abstract: To solve the contradiction between matching precision and matching speed in stereo matching for dynamic programming, TRIZ theory was introduced. After locating the contradiction in 39 contradiction matrix and getting the solutions for the matrix, we get the TRIZ advice. With this guidance, we apply the pyramid algorithm on low resolution images and adopt bidirectional dynamic programming strategy on disparity space image to speed DP process and then the ground control points were attained. Experimental results showed that the proposed method in the paper has higher matching precision with less time.
