In order to solve the problems of manual inspecting GAT0 propellants shape and surface, design GAT0 propellant intelligent inspecting system. The automatic intelligent inspection plan based on image inspecting technology is put forward, use image inspecting mode to inspect pipe dimension and appearance defect, then adopt special simulation and simulation tool to analyze system. Analyze intelligent inspecting system data acquisition, and combine with propellant machine vision inspecting technology to acquire the implementation effect of intelligent inspecting system. The implementation results show that the design can improve the quality of propellants, and keep the propellants producing more safety in high efficiency.
