Study on Inner Diameter Measurement of Cannon Barrel Based on Image Processing

Cannon barrel life is an important tactical characteristic of the cannon to maintain combat capability, and the inside diameter wear of the cannon barrel is one of the most important appraising standards of cannon barrel life. In this paper, a cannon barrel inner diameter gauge is designed based on the CCD imaging and computer image processing technique. The main idea of design and the working procedure and the design principle of the main components of the inner diameter gauge are introduced, in the end the various measurement errors are analyzed.
