Lingfu Kong · Jisuanji gongcheng · 2009
Aiming at the problem of error matching and straitness occluding in dynamic plan matching algorithm, a stereo matching algorithm for contour map ground control points extraction is proposed. It chooses the ground control points in virtue of contour perceiving. The dynamic plan is used to search the best path in disparity space image. The disparity image is perfected based on the constraint of disparity image and the determinant formula of straitness occluding. Simulation experimental results show this algorithm can reduce the false matching rate in disparity’s discontinuity areas matching.
