Cigarette appearance defect visual detection system and detection method thereof

Abstract

The invention discloses a cigarette appearance defect visual detection system and a detection method thereof. The cigarette appearance defect visual detection system comprises an image acquisition module, an image processing module, a controller module and a rejecting module, and is characterized in that the difference between a target and the background is obtained clearly by arrangement of a light source, the good light source can effectively take in information and reduce interference, and through an AI algorithm, two-stage detection is carried out on the defects of the cigarette, the detection accuracy is greatly improved, two CCD cameras are used for collecting images of the outer surface of the cigarette, an advanced image analysis processing algorithm is used, the defects on the surface of the cigarette can be accurately analyzed and detected, and the defect type is distinguished through the AI algorithm, if the cigarette is abnormal, an alarm can be prompted or a machine can becontrolled to stop, and cigarettes which do not meet requirements can be rejected after being detected. According to the system, the labor intensity of the detection personnel can be effectively reduced, the detected products can be finely classified, the product quality can be improved, and the actual production can be guided by utilizing big data.

Description

technical field [0001] The invention relates to the technical field of cigarette visual detection systems, in particular to a visual detection system and detection method for cigarette appearance defects. Background technique [0002] Cigarettes are favored by the majority of consumers, leading to an increase in the scale of cigarette market expansion year by year, showing a blowout development trend. In modern cigarette production, the finished small packs of cigarettes go through carton packaging, carton transparent paper packaging, carton beautification, package missing detection, carton transportation and other links, and finally enter the sealing machine. In all links before entering the box sealing machine, there are factors that affect the appearance quality of cigarettes. In actual production, the appearance quality of cigarette sticks is a focus of defect detection. [0003] In the traditional inspection process of cigarette appearance defects, the appearance qual...

AI Technical Summary

Problems solved by technology

[0003] In the traditional inspection process of cigarette appearance defects, the appearance quality of cigarettes is inspected manually. Since the products of the production line are inspected by eyes for a long time, people are prone to fatigue, and the work intensity is very high. Moreover, the manual inspection standards are not uniform. , the detection speed is slow, the efficiency is low, and the detection accuracy is not enough
