Abstract: A stereo vision based pose measurement method is proposed for noncooperative space targets. Laser radar can provide prior information such as distance and position for binocular vision system. Based on the information, the search area can be narrowed for the image pair because the disparity is determined for a certain distance. The compute complexity can be reduced so that measurement efficiency is improved. Meanwhile, algorithm is more robust because the texture complexity caused by stray light is lower at local area than global image. A closedloop experiment is conducted to validate the performance of proposed method.

Key words: noncooperative targets, match point, complexity
