摘　　要：双目立体视觉是以Ｄ．Ｍａｒ的计算视觉理论为基础，从二维立体图象对中恢复距离信息的有效途径，其中的立体匹配部分是它的核心步骤．文中提出了一种基于边缘特征的立体匹配方法．该方法在一种逐渐放宽约束条件的渐进匹配策略控制下，通过边缘检测、相似性检验和相容性检验完成了匹配的全过程．并针对水平边缘误匹配率高的问题，提出视差限制的方法加以解决．实验结果表明，文中提出的匹配方法是有效而可行的．The binocular stereo vision, based on D.Marr's computational stereo theory, is an efficient approach for recovering range information from 2D images, in which the stereo correspondence is its key part. A stereo matching approach based on edge feature is proposed in this paper. The procedure of the correspondence is fulfilled through the edge detection,the similarity check and the consistence check, controlled by a matching strategy relaxing gradually the constraints. At the same time, for the solution of higher false matching rate in horizontal edges, a method of disparity limitation is suggested. The experimental result shows that the matching approach proposed is efficient and feasible.
