一种用于交会对接的CCD快速测量方法
A Fast CCD Measurement Method Used in Rendezvous and Docking
摘要
本文设计了一种用于交会对接的双 CCD测量系统, 给出了目标航天器上标记点在交会坐标系中的定位算法, 并将这种定位算法推广到三个标记点的情形, 由此导出了目标航天器在交会坐标系中的位置、姿态矩阵以及三个姿态角。与计算机视觉技术的处理算法相比, 本文中提出的算法更加简单, 运算速度更快, 更适合用于交会对接的场合。
Abstract
A two-CCD measurement system used in rendezvous and docking is designed, and the positioning algorithm of a marker lamp on target spacecraft is given with respect to a rendezvous and docking coordinate system. Then, the algorithm is extended to the case of three badge lamps, and accordingly the position, attitude matrix and three attitude angles of target spacecraft are educed with respect to a rendezvous and docking coordinate system. Compared with the algorithm of computer vision, the algorithm proposed in this paper is simple, fast and proper to application in rendezvous and docking.
