光学图像中空间物体条痕检测方法综述OA北大核心CSTPCD

Space objects frequently appear as elongated stripe patterns,known as streaks,in optical images.The accurate detection of streaks is of great significance for the recogni-tion and measurement of space objects.In recent years,many researchers have studied the detection methods of space object streaks and achieved fruitful results.With the improve-ment of the detection ability of space objects,the detection of faint streaks has become more and more important in realizing comprehensive and accurate space object detection.This paper provides an overview of the main principles and steps of space object streak detec-tion methods in optical images.It classifies and summarizes these methods based on their characteristics,and selects four representative single-frame image-based algorithms for space object streak detection from different categories.Experimental comparisons of these four methods are conducted using both simulated and measured images.Based on the experi-mental results,the advantages and disadvantages of each method are analyzed.Finally,the future development directions of streak detection methods in optical images are prospected.
