摘要
在对大视场天文定位系统多星同步检测中的星体目标和噪声特性进行分析的基础上 ,提出了采用图像平滑滤波、灰度拉伸及二值化、目标相关处理等较为实用的星体目标提取算法。实验结果表明 ,该图像处理算法效果良好。
On the basis of analyzing the specific for the star targets and noise,the article describes a practical algorithm of star target examining which including image smooth,graystretch and binary image,correlation in wide field of view celestial positing. The results of experience show the effect of the algorithm is good.
