摘　　要：真正射影像不仅具有地图的几何精度,可以直接进行地物尺寸和距离的测量,而且具有更好的视觉效果。有效的遮挡检测是真正射影像制作关键环节,国内外学者提出了许多遮挡检测算法,在进行遮挡区域检测的过程中各有优劣。通过对主要的遮挡检测算法原理和处理过程进行对比分析,总结了各个算法的优缺点,为寻求高效准确的遮挡检测算法提供参考,并提供了一些可以改进的建议。True orthopboto has not only the geometric accuracy of map, can be directly measured object size and distance, and has better visual effect. Effective oeclusiou detection is a key link in true orthophoto production, domestic and foreign scholars have put forward a lot of occlusion detection algorithm, in each have advantages and disadvantages in the process of the occlusion detection. Based on the comparative analysis of the main occlusion detection algorithm principle, summarizes the advantages and disadvantages of each algorithm, for reference to the efficient and accurate occlusion detection algorithm, and provide some suggestions for improvement of occlusion detection Algorithm.
