Guide Star Database Creation for the Star Sensor Based on ITSI Selection Algorithm
摘要
Abstract
A guide star database based on a new guide star selection algorithm is properly built,in order to improve the performance of the star pattern recognition for the star sensor. The selection algorithm is preferred by improving the traditional algorithm,through the process of regional segmentation and star-density calculations. Meanwhile,a software platform is established based on SAO star catalog. Through it,different star patterns can be put out according to the actual needs,including the range viewing angle,tracking position,pixel sensitivity and other restricted conditions. The new selection algorithm is used to select guide stars among the stars of the above star pattern. Ultimately the guide star database can be built. The algorithm is proved better to solve the problem of navigation star uniform distribution by uniformity evaluation criteria. Finally,by building the guide star database,the complexity of the star pattern identifica-tion can be effectively reduced,and the matching rate can also be greatly improved as long as the star pattern recogni-tion rate.关键词
