摘　　要：计算机双目立体视觉技术是获取图象中景物的三维深度信息的有效途径，其中关键步骤是立体图象对间对应象点的匹配。本文提出了一种基于边缘特征的匹配算法，通过边缘特征提取，相似性检验和相容性检验完成整个匹配过程；经实验表明，该算法匹配速度快，匹配率较高。通过对积木图象对匹配后三维重建显示，重建结果令人满意，证明算法是可行的。The computer binocular stereo vision is a effective way for obtaining the depth infor-mation of objects in image.Stereo matching is its key step be tween the corresponding plxel in a pairof stereo image.In the paper, a stereo matching algorithm based on edge feature is presenled. Thematching procedure is bulfilled by extracting edge and checking similatirity and consistence. Experi-ment shows that the algorithm has faster matching speed and higher matching rate. Reconstructionfor the matching result of block images shows that the result is satisfactory and the algorithm is effec-tive.
