摘要: 随着对地观察测绘卫星、深空探测卫星对姿态测量精度要求的提高,进一步提高星图匹配精度是当前面临的重要课题之一。星点提取和定位是星图识别的前提。本文简单探讨了新型Top-hat变换的星点提取方法,通过实验对比分析了三角形星图匹配算法和采用P向量的星图匹配算法优缺点。

Abstract: With the improvement of attitude measurement accuracy requirement of Surveying and mapping satellite and deep space exploration satellite, it is one of the important issues to further improve the accuracy of star map matching. Star extraction and positioning is a prerequisite for star pattern recognition. This paper briefly discusses the new top hat transformation method of star extraction. By comparing the experimental analysis of the triangle star pattern matching algorithm and the vector P star map matching algorithm advantages and disadvantages.
