摘　　要：介绍了星敏感器的基本工作原理,分析了星图的特点,进行了噪声的预处理。在星体识别过程中对传统算法进行了改进,提出了一种适合星图的二值图象标记算法,对星体进行了有效识别。并用实拍的星图进行了实验仿真,取得了较为满意的结果。The basic principle of star sensor is introduced and the characteristic of star image is analyzed. Based on these analyses, a strategy for star image＇s noise pretreatment is presented.On the process of star identification, the tradition algorithm is improved and a suitable alogrithm ofpixel labeled in binary image for star image is presented. The star is identified availably with this method. At last the star image is simulated and satisfying result is obtained
