The position and pose measurement for space non-cooperative target is an intractable problem of on-orbit servicing for space non-cooperative target, which has been a hotspot of research in recent years. In this paper, firstly, the characteristics of the position and pose estimation for space non-cooperative target are discussed. Secondly, the performance of the main position and pose estimation optics methods are comprehensively summarized. Finally, the vision sensor and estimation algorithm are analyzed, and their advantages, disadvantages and application area are concluded.
