A Pose Measurement Method of a Non-Cooperative Spacecraft Based on point cloud feature

摘要

This paper investigates the Attitude measurement for the Non-Cooperative Spacecraft problem. Considering there are no or few prior knowledge for the target, an autonomous measurement method for relative position and attitude of space non-cooperative spacecraft is proposed to solve the problem of relative position and attitude measurement of non-cooperative spacecraft in orbit capture in this paper. Specifically, a normal feature extraction method based on satellite plane is adopted, which can provide a good initial condition for solving the attitude matrix of the final target. The relative position and attitude of the satellite can be measured even if the rotation angle of the target is very large. Experiments show that the pose and motion method for measurement proposed in this paper has high accuracy and good stability.
