Abstract: The flaws of barrel of anti-aircraft artillery may influence the accuracy of launching and safety of use during launching. A device of detecting the flaws of artillery barrel is designed using optical-electron-mechanical control technology and CCD imaging technology based on the structure of bore. This device is used to investigate the surface appearance of inner bore through 360 ° panoramic imaging, thereby examining the surface of inner bore qualitatively and quantitatively. It has the functions to position the flaws, compare the types of flaws and measure the sizes of flaws on barrel automatically. The system can be driven to move along the barrel axis, thereby effectively identifying the flaws on bore and making a comprehensive assessment.
