True orthophoto has not only the geometric accuracy of map, can be directly measured object size and distance, and has better visual effect. Effective occlusion 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.
