Cigarette package appearance defect detection method and system

Abstract

The invention provides a cigarette package appearance defect detection method and system. The method comprises the steps that a first following window and a second following window are arranged, whena photographing triggering signal is received, a box body of a to-be-detected cigarette package is positioned through the first following window, and a box cover of the to-be-detected cigarette package is positioned through the second following window; a box body image of the first following window and a box cover image of the second following window are acquired, and the offset of the box body and the box cover of the to-be-detected cigarette package is determined; state information of the to-be-detected cigarette package is determined according to the offset, a detection window is set according to the state information to detect a key defect detection area of the to-be-detected cigarette package, and then a detection image of the to-be-detected cigarette package is acquired; and similarity comparison is conducted on the detection image and a preset template cigarette package image to screen out the cigarette package with the appearance defect. According to the cigarette package appearance defect detection method and system, the intelligence of cigarette package appearance quality detection can be improved, and the false detection rate of cigarette package appearance defect detection is decreased.

Description

technical field [0001] The invention relates to the technical field of automatic control of cigarette pack production, in particular to a method and system for detecting appearance defects of cigarette packs. Background technique [0002] Consumers can intuitively feel the appearance quality of cigarette packs at first sight. Appearance defects will reduce consumers' trust in cigarette brands and affect the sales of related products. However, in the cigarette packaging process, there are many processing procedures, and appearance quality defects will appear throughout the packaging process, such as uneven folding, improper pasting, scratches or damage, and misuse of packaging materials. Therefore, an effective appearance defect detection system is needed to eliminate appearance defect products and ensure the production of qualified products. At present, cigarette factories mainly use smart cameras to take pictures of cigarette packs, and conduct appearance quality inspectio...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a method and system for detecting appearance defects of cigarette packs, which solves the problem that the box body and the box cover are not bonded in the production process of existing cigarette packs, which easily causes low detection accuracy and high false detection rate in the detection of appearance defects. It can improve the intelligence of cigarette pack appearance quality detection and reduce the false detection rate of cigarette pack appearance defect detection
