Design of image processing subsystem in satellite laser ranging system

In order to improve the automation of the satellite laser ranging system,an image processing subsystem for SLR is designed. The image processing method is used to calculate laser beam peak centroids and satellite position,and the laser pointing was adjusted and prediction deviation was corrected through the image processing results. Firstly,the framework and flowchart of the image processing subsystem are given. Then,the main design of the algorithm is introduced emphatically. Finally,the system performance is verified by actual test.The experimental results show that the image processing subsystem operates normally and stably. It can satisfy precision and real-time requirement of laser ranging system,which is of practical value.
