为自主完成空间服务任务,需要满足各种功能需求、突破多种关键技术。针对在轨服务中具有圆特征的非合作目标空间圆(星箭对接环、发动机喷管等),首先分析了非合作目标空间圆检测技术在在轨服务系统中的主要应用;然后提出了一种非合作目标空间圆的检测方法,通过Canny算子检测边缘,并用Freeman链码法对边缘进行提取分类,再利用RED算法进行非合作目标空间圆检测;最后给出仿真结果,在保证检测精度的前提下,较传统的RED算法明显降低了算法的耗时量。

In order to complete the on-orbit service independently , various functions need to be satisfied and many key technologies be solved .This paper mainly studied the detection algorithm for the space circle of non-cooperative target such as the docking ring of satellite and rocket and engine nozzle.Firstly, the main applications of the detection algorithm for the space circle of non-coopera-tive target in the on-orbit service system was described .Then a detection algorithm for space circle of non-cooperative target was proposed .Canny operator was used to detect the edge .Freeman chain code method was used to extract and classify the edge .After that , the RED algorithm was used to detect the space circle of non-cooperative target .In the end , the simulation results were given in the paper.Experimental results showed that: the proposed algorithm had a higher detecting precision and shorter consumed time as compared with that of the traditional RED algorithm .
