一种自主星图识别算法

摘要

Researches on several existing star pattern recognition technologies are carried out in this article.To improve the efficiency and reliability of star sensor system,a new advanced star pattern match algorithm—based on the essential algorithm named Eigenvector Projection Method (EPM)—is designed,programmed,and tested in this article.This algorithm is designed to reduce data capacity of the star database and to improve the speed of processing.According to the test results,this new algorithm has successfully improved the efficiency and reliability of the star map recognition system.%为了改善星敏感器系统的星图识别实时性和可靠性,文章在研究现有的星图识别相关技术基础后,提出了基于特征向量投影法的算法核心,并在这一核心的基础上完成了星图识别算法和导航星图数据库的改进设计.最后编写仿真测试软件对此算法程序进行了性能测试,测试结果表明,文章提出的自主星图识别算法在星图识别实时性和可靠性方面都较以往算法有了提高.
