传统的三角形星图识别算法冗余匹配多,对噪声鲁棒性差,为此,为了提升获取恒星质心位置精度,提出了一种基于恒星星等差和点对距离的恒星星图匹配方法,完成了星空图像中恒星的识别与匹配。实验结果表明,获得的恒星质心位置具有较高的精度,在实际拍摄近红外星空图像恒星目标的匹配与识别过程中具有较好的应用前景。

The star identification is a key technology of near infrared starry-sky image navigation. We can calculate the position of the imaging platform after the identification of at least three stars. The traditional star identification algorithm has a higher redundancy and a poor robustness to noise, so , for more accurate results of identification, in this paper, we designed a method of star matching and identifying based on the two characteristics of magnitude differ and star point pairs. It can bring high accurate of the.
