Abstract
The traditional orthophoto rectification often suffers from the problems of building lean and double mapping, etc., which are caused by no detecting the occluded areas, therefore, many improved occlusion detection methods had been discussed to solve these problems, such as angle and height based ray tracing method, angle-based method and Z-buffer method, etc. Angle and height based ray tracing method based on two different DSM models will be discussed in this paper, Experimental results demonstrate that the accuracy based on TIN DSM is better than that based on dense grid DSM.
