Paper Abstract

In the on-orbit maintenance task of aircraft, it is often necessary to operate non-cooperative targets. Relative pose measurement of non-cooperative target is one of the key technologies. In this paper, a fast method for detecting the artificial characteristics of non-cooperative object in the images of CCD cameras in ultra-close range is presented. The detection target here is the ellipse formed by the projection of the circular structure on the imaging plane. The geometric parameters of the circular is fitted by binocular vision matching of the detected ellipse, and a invariant point feature on the non-cooperative target is recognized and selected, which is combined with circular normal to establish the coordinate system of non-cooperative target, then the relative pose of non-cooperative target can be calculated, and the algorithm for measuring the relative pose of non-cooperative target are formed. The test results show that the algorithm is accurate and effective, and meets the requirements of accurate measurement and positioning technology in on-orbit service.
