【Abstract】 Based on the image processing and computer vision, a system of SEM three-dimensional surface measurement and reconstruction has been established on personal computer. By using of reconstruction principle and characteristic of SEM stereo pairs, a feature-constrained stereo matching algorithm is presented. The results of the algorithm are proved to be with high efficiency and good precision. The max relative depth value measured and the actual value coincide basically. The reconstruction of the representative fracture surface directly is carried out on the system.更多还原
