摘要(中) 追星儀為衛星與太空戴具辨別姿態的系統元件，主要功能在於
對其拍攝之星圖影像進行分析而得到衛星或太空戴具的姿態。而在
做分析時，星圖的影像處理為相當重要的課題，影響了星體的辨識
及最後計算姿態的準確性。
本文貢獻為提出尋找星圖影像星體的尋星演算法，有效的尋找
出星圖影像中的星體位置以及亮度;以及星體編碼的前置動作選星
吻合度演算法將尋完星圖後的星體與星資料庫做相互比對提供一定
的精準度，供之後星體編碼動作進而完成星圖辨識。
摘要(英) Star trackers are a staple subsystem of satellites or
space vehicles, which using star identification to determine
the attitude. At analysis, star image processing is the
biggest study which affect the final calculation of star
identification and attitude accuracy.
This paper develop the find stars algorithms of star image
processing, effective to find out the star map images of the
position and brightness of stars; and pre-encoded motion
stars selected to sing the degree of matching algorithms to
find complete star chart star after database to do with each
other to provide a certain degree of accuracy than to provide
some precision, for after completion of the stars and then
coding the action star map identification.
