摘要:
    三角形星图识别可靠性与可操作性较强,目前仍在广泛使用,但是三角形星图识别算法存在冗余匹配和误识别。通过星点的几何分布构建星点的径向特征量,依据径向特征量对星图进行初始识别,将拍摄星点的识别结果限定在数颗导航星上。在初始识别的基础上,运用三角形星图识别算法再次进行识别,使三角形星图识别更具针对性,同时提高识别的正确性。实验结果表明,采用基于径向特征的改进三角形识别算法,星图识别的准确性和针对性都得到了提高。

Abstract:
    Triangle star identification has strong reliability and operability, and is still widely used at present, but the triangle star identification algorithm poses problems of redundant matching and wrong identification. The radial feature quantity of the star point was constructed by the geometric distribution of the star point. The star point was initially identified, and the navigation star corresponding to the star point was limited to several navigation stars by initial recognition. On the basis of initial identification, the triangle segmentation identification algorithm was used to identify the initial recognition result again, which improves the pertinence and efficiency of star map identification. The experimental results show that when the new algorithm is used to identify the stars, the accuracy and rapidity of star identification are improved.
Key words:  triangle  star identification  radial feature  initial identification  accuracy
