基于形态学操作的空间点目标检测算法

For space-based spatial target detection , a method for mobile spatial probe detecting spatial point target on the stellar background is proposed in this paper , which is base on the morphological operations and frame difference，this method takes advantage of the location difference of stellar and spatial point target. The algorithm are as follows: first, template matching method is introduced to complete the image registration, second, dilate the first frame image and erode the second frame image, after finishing the two image difference and threshold operations, the location of spatial point target can be obtained at once. According to the experiments on the image sequence, each image of which includes moving spatial point target and moving stellar, the new image processing algorithm can eliminate the interference of stellar in the space environment effectively and extract the location of spatial point target .
