Abstract: A stereo vision-based measurement and planning method is proposed for space robot to capture a non-cooperative target.The method is composed of image processing and feature extraction,3D reconstruction and pose measure-ment,and autonomous planning and control.Furthermore,a simulation system is created,and the closed-loop simulations,including image collection,pose measurement,chaser GNC(guide,navigation and control),space robot planning and control,and satellites'dynamic calculation,are conducted.The simulation results verify the algorithms above.
