The paper describes a rapid algorithm to detect the deficiency of plastic bottle cap and the cap sealing ring if it is stained without touch. The algorithm includes image preprocessing, extraction of the interesting region and cap edge, defect detection and so on. The rationality and stability of the online inspection system are proved by theory and test. The algorithm can detect more than 36,000 caps per hour and 0.1mm defects.
