摘　　要：灌装PET瓶的实时自动检测在实际生产中具有重要的作用。在当前生产中,存在着瓶子抖动对图像算法的影响,提出了可以克服上述问题的瓶盖检测方法。采用基于直线拟合算法对灌装PET瓶的实时自动检测算法进行设计,通过对瓶盖所在直线的拟合以及支撑环所在直线拟合,实现了灌装PET瓶的液位缺陷的检测类别判断功能,并且克服了高速生产中瓶子抖动对图像采集以及瓶盖判断的干扰。实际系统监测准确率达到99%以上,实验证明算法有很好的鲁棒性。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.
