Abstract

A heated cigarette end quality inspection system based on machine vision detection technology had been designed to address the difficulty of online detection of common quality defects such as cigarette deformation, hollowing, and looseness at the end of heated cigarettes. The system utilized hardware such as high-speed counting cards, industrial cameras, and flash controllers to complete image acquisition, and the Canny algorithm was used for cigarette contour detection and recognition in the industrial computer. Then, cigarette deformation was determined based on the mean and standard deviation of the contour radius, cigarette hollow was identified based on global threshold binarization, and cigarette hollow was identified based on local adaptive binarization. Based on the recognition results, the end defects of cigarette deformation, hollow, and loose were eliminated online. The performance of the binary algorithm used in the system and its practical application in production had been validated. The results showed that compared with OTSU, Bernsen, Niblack and other methods, global threshold binarization had the highest accuracy (99.8%) in empty detection, and adaptive binarization had the highest accuracy (99.0%) in empty detection; The system had a detection accuracy of ≥ 99% for defects such as deformation, hollowing, and looseness of heated cigarette ends, and had significant advantages in calculation time. It was suitable for high-speed operation requirements of production lines and can provide support for improving the quality of heated cigarette ends and production process control.
