Abstract

Space weak point targets detection is very useful in non cooperative target detection. Influenced by the chip noise and space environmental noise, weak point targets detection becomes a difficulty. In the paper, firstly the star is extracted from the picture, the background picture is filtered to reduce the noise, and then the moving distance between adjacent pictures is calculated, after picture overlapping between adjacent pictures, the energy of the weak point target is improved, with a appropriate threshold, the weak point target is extracted. The proposed method can be widely utilized in space exploration, space defense etc.
