%X The actual real-time automatic inspection of the PET bottles plays an important role in production. In the current production, shake of the bottle gives a negative influence on the inspection algorithm. This paper aimed at designing an algorithm which could overcome the problem above. Based on this linear fitting algorithm, this paper designed a real-time automatic detection method. Through inspection of the straight line through the cap and the support ring,the method could categorize the defected cap, and overcame the bottle-shaking caused by high-speed production. The accuracy rate reached more than 99% in the experiments on the online production system. Experiments show that this algorithm has good robustness.
