Pose measurement and ground validation Based on lidar in-orbit

Abstract

An effective ground validation method is proposed to solve the difficult problem of non-cooperative target position measurement in-orbit verification. First of all, this paper highlights the effectiveness of a light fuzzy target point cloud model visible part judgment method to search. Secondly, laser reflection intensity is used to realize the point cloud registration process, not only the influencing factors of the space radiation source to the image, but also the incident angle imaging quantitative analysis. Finally, points cloud precise registration is achieved according to the iterative algorithm. This method realizes the ground verification work of the robustness, real-time performance of the position, attitude measurement algorithm, and shortens the study cycle of the future on-orbit control task.
