交会对接最后逼近阶段的CCD相机测量方案

Method of Measurement in the Phase of Final Approaching for Rendezvous and Docking in Spce

本文提出在交会对接最后逼近阶段,采用任意安装的CCD相机及激光二极管阵列,测量追踪飞行器相对于目标飞行器的位置和姿态的方位角法和成像法测量方案,以及在采用单机和多机时的算法,并进行了分析比较。采用单机时,精度很高,而采用双机或多机,算法简单,速度快。将两者结合起来,可以较好地解决该阶段的测量问题。

This paper offers two measurement schemes using CCDcameras during the phase of the final approaching. For one or more than one cameras, the algorithms are not the same. The algorithm based upon two or more cameras is fairly easy and fast, and the one based upon one camera is possibly more accurate. Combination of two means can well deal with the measurement in the phase of final approaching.
