영상처리시스템을 이용한 피스톤 상면 결함검출에 관한 연구

The piston is an important element which converts a power in the engine parts. The external defect(crack, cavities) of piston have bad effects on the durability because the operational environment is high temperature and high pressure. We present that detecting defects and recognizing characters on the piston head using Image process system. In this paper, we describe the constitute of camera and illumination system for inspection of metallic product. Also, We develop the software which has simple algorithm and fast processing speed. It will be able to apply an automatic inspection system that it is better than the inspection being dependent on a man power in terms of error rate.
