Abstract A new fast stereo edge-matching algorithm based on mountain images is presented. In order to ensure the accuracy of the match. Firstly the disparity gradient restriction across the direction of epipolar lines is used, and then on the basis of exclusionism searched the corner information close to edge point to guide the matching with restricted corners-searched range. The final match results ensure that the matching pairs in two images are one-to-one correspondences. The algorithm results show that the amalgamation of different restrictions improved the matching speed and precision.
