融合SGM与Z-Buffer的真正射影像遮挡检测算法
A true orthophoto occlusion detection algorithm based on SGM and Z-Buffer
摘要
Abstract
A true orthophoto detection algorithm based on SGM and Z-Buffer is proposed to solve occlusion problems caused by tilt photography on high buildings in the process of true orthophoto generation.This algorithm uses occlusion information accessed by the SGM dense matching method as an occlusion criterion and combines with the traditional Z-buffer occlusion criteria to accurately detect the occlusion area.The experiment makes a comparison for aerial stereo image between this proposed algorithm and the traditional algorithm.The result shows that the proposed algorithm has higher accuracy on occlusion area detection and solves the pseudo visible problem.关键词
