交会对接成像软件的多目标跟踪改进

介绍交会对接成像敏感器的工作原理以及由单组条带预判窗口跟踪模式的单一目标敏感器组成的交会对接测量系统.从敏感器嵌入式软件的层面，提出多目标窗口计算、多目标条带预判、多目标匹配计算和多目标测量结果处理等4项改进方法，在硬件系统完全不变的情况下，改善多目标跟踪交会对接敏感器性能.该项改进将单机系统提升为多机热备份系统，提高系统安全性.实现不同目标器之间的自主跟踪切换，优化交会对接流程.此外，变不同敏感器之间切换为敏感器处理对象切换，提升交会对接过程的可靠性.改进后的算法已在我国交会对接各重点型号试验中顺利应用.

Improvement of Track Software for Multi Target Image in Rendezvous and Docking

The principle of rendezvous and docking image (RVD) sensor is introduced. The measure system of one target RVD image sensor with image track windows is presented. Without any change in the hardware of the sensor, four improvements of embedded software are brought to multi target RVD image sensor, such as multi target calculating track windows, multi target prediction of image row windows, multi target image match and multi target results optimization. The safety level ascends when the measure system becomes multi spare mode. The automatic switch within different targets improves the process of RVD. The independence level is greatly improved while the switch of different camera is replaced by different spots in images from one camera. The improvements are already used in many missions of RVD in China.
