Due to the development of aerospace technology in China, this paper proposes a method of characteristic line detection and matching to reconstruct the non-cooperative target. The geometric and algebraic constraints are given by its 2D images, and the linear equations about position and attitude of the aircraft relative to the non-cooperative target are deduced by n lines (n > 13). Then, by using...
The planetary lander usually selects image feature points and tracks them from frame to frame in order to determine its own position and velocity during landing. Aiming to keep features tracking in consecutive frames, this paper proposes an approach of calculating the field of view (FOV) overlapping area in a 2D plane. Then the rotational and translational motion constraints of the lander can be found...
This paper presents the problem of reconstructing the 3D terrain model for landing of small body spacecraft, in order to approach and land on a small body successfully. We propose an on-line terrain modeling using image sequence provided by an on-board camera. The recursive structure from motion algorithm and the orthography factorization algorithm are proposed to recover the depth maps. The application...
