| 针对目前PET瓶饮料生产线的封盖缺陷依靠人工检测效率低的问题，笔者提出了基于视觉的PET瓶封盖检测及定位系统。设计了3相机加背光源剪影成像的方式，实现稳定有效的采集目标轮廓信息；采用Canny算子寻找二值化图像瓶盖边缘，利用最小二乘法拟合盖顶轮廓线等处理方式，实现对高盖、歪盖、无盖和低液位等缺陷的识别；基于Visual Studio 2019设计了人机操作界面，采用modbus tcp通信协议实现与PLC的通信；设计光电信息系统，对造成相关缺陷的旋盖机工位进行定位。结果表明：该系统运行稳定，检测速度快，满足当前绝大多数饮料生产线；识别准确率高，能有效剔除缺陷产品；定位精准，能够准确的定位旋盖机异常工位。课题组的研究实现了对饮料产线上封盖缺陷的准确识别和剔除，提高了产品合格率。 |

| Aiming at the low efficiency of manual detection of the capping defects in the current pet bottle beverage production line,a detection and positioning system of PET bottle cap based on vision was proposed. A three camera plus backlight silhouette imaging method was designed to achieve stable and effective acquisition of target contour information; the image processing algorithm was designed to recognize the defects such as high cover, crooked cover, no cover and low liquid level; the man machine operation interface was designed to realize the communication with PLC and the real time display and archiving of detection information; the photoelectric information system was designed to locate the capping machine station causing relevant defects. The results show that the system runs stably and has high detection speed, which can meet the needs of most beverage lines at present; the system has high recognition accuracy and effective elimination of defective products; the system has accurate positioning and can accurately locate the abnormal position of the capping machine. The system realizes the identification and elimination of cover defects in beverage production line, and improves the qualified rate of products. |
