摘　　要：针对星敏感器星图识别算法只能处理少数目恒星的问题,结合天文观测相机进行星图识别的具体要求,提出了一种适合天文观测相机的多三角形星图识别算法.首先,选用欧洲空间局2000年2月发布的第谷2天文星表作为原始导航星表;其次,采用交叠矩形法分天区后建立导航星数据库;最后,根据天文观测相机拍摄的实际星图建立了观测星数据库;并应用多三角形星图识别算法进行星图识别的验证,实验结果表明:针对天文观测相机多三角形星图识别算法是可行的,也是可靠的.After considering the specific requires of the star pattern recognition of the astronomical camera, a kind of multi-triangle star pattern recognition algorithm was presented according to the problem that few stars are only processed by star map recognition algorithm of star senser, which is suitable for the astronomical camera. First, the Tycho-2 Catalogues, which is issued by the European Space Agency on February, 2000, is regarded as the original navigation catalogue. Second, the database of the navigation star was founded after the sky region was divided by using the overlapping rectangle method. Finally, the database of the observation stars was founded according to the real star field by the astronomical camera, and the star pattern recognition was verified by using the multi-triangle star pattern recognition algorithm. From the experimental result,it was found that the multi-triangle star pattern recognition algorithm of the astronomical camera is feasible and credible.
