- Abstract
Navigation control of spacecraft is one of tlie key technologes in deep space exploration. However, As the exploration distance is getting farther,the limitations of traditional ground station control become more obvi¬ous. Therefore,autonomous optical navigation has become the development direction of aerosjDace exploration in the future. The edge detection technology is one of the critical algorithms in optical autonomous navigation. In order to meet the real - time requirement of on - board computing,this study proposed an optimized Canny edge detection al¬gorithm and the circuit architecture of FPGA to optimize the non - maximum suppression and adopt dynamic single threshold of Canny edge detection algorithm. In this way,it could be implemented on the FPGA witli less resource oc-cupation and pipeline architectiure. Finally,the real - time requirement of optical autonomous navigation was satisfied on the promise of guaranteening the accuracy of edge extraction and it had good robustness to complex star targets.
