Study on Extraction of 3D Point Cloud under Occlusion Conditions

SHENG Qing-hong et al (College of Astronautics,Nanjing University of Aeronautics & Astronautics,Nanjing,Jiangsu 210016)  
According to the occlusion problem in the extraction process of three dimensional information,it was proposed to carry out multi-light image matching by using the multi-baseline digital close-range photogrammetry method,the filtering algorithm of 3D point cloud based on the occlusion region constraints,not only wiped off the occlusion object,but also extracted part of three dimensional data points in the occlusion region.The experiment indicated that the method was applicable to the discontinuity in spatial distribution and better solved the target occlusion problem under the occlusion condition,meanwhile the multi-directional intersection left the forward intersection with redundant observation,which added the reliability of three dimensional data points.
