基于点云曲线辨识的卫星激光数据预处理算法
DATA PRE-PROCESSING ALGORITHM OF SATELLITE LASER RANGING BASED ON CURVE RECOGNITION FROM POINTS CLOUD
摘要
Abstract
In order to solve the pre-processing algorithm of SLR data, the SLR data from the COMPASS quality is analyzed. The difference between curve recognition in the fields of reverse engineering with computer vision and pre-processing algorithm of SLR data is discussed, and then a new algorithm of satellite laser ranging data pre-processing based on curve recognition from points cloud is proposed. This algorithm treats SLR data processing as a problem of curve recognition with organized points. The algorithm is checked by using the SLR data from the COMPASS. The results show that the rate of accordance between results of the new proposed method and the screen displaying method can reach 85％ or higher. Accordingly, the new method can be used for SLR processing data automatically and meet the need in building the navigation system.关键词
