摘　　要：为了提高星敏感器的测量速度和精度,在星图识别中首次采用了在地球物理地质建模中有着广泛应用的剖分算法。利用这一算法进行星图的匹配识别,仿真实验结果表明与现有的星图识别算法相比,此算法具有高的识别率,良好的实时性和鲁棒性,且所需导航星库的容量小,检索速度快。In order to improve the measuring-speed and precision of star sensor, cutting algorithm which is used far and wide currently in the field of physical geography is adopted first in the area of star map identification. Using this algorithm to identify star map, the simulation results show that compared with the current star map identification algorithm, this algorithm presented has the advantages of real time properties and robust; it only needs a small content database and searches data rapidly.
