| 摘 要： | 电荷耦合器件CCD星敏感器的关键问题是星图识别,星图识别就是从星敏感器获得的原始星图中获取星的位置和星等信息。在介绍星敏感器工作原理的基础上,初步探讨了电荷藉合器件（CCD）天文定位的应用和优点,重点分析了Moravec算子、Frstner算子、Harris算子等几种点特征提取算子的原理和其适用性。

| Abstract: | The key function of the CCD star sensor is the recognition of star image.The star image recognition is to get the position of star and information of stellar magnitude from the original star image of star sensor.In this paper,based on the introduction of working principle of star sensor,the application and virtue of CCD astronomical positioning is initially discussed,and the principle of several point characteristic extracting operators that are the Moravec,Frstner and Harris operators are mainly analysed. |
