Method and system for evaluating soft package cigarette package forming quality

Abstract

The invention provides a method and system for evaluating the forming quality of a soft-package cigarette package, and the method comprises the steps: setting key forming positions of the soft-package cigarette package, and carrying out the image detection of the key forming positions, the key forming positions including a trademark bottom folding position, a side folding position, a seal pasting position and a pull line position; performing key region area positioning and rotation angle calculation on the detection image of the key forming position by adopting an ORB feature extraction and matching algorithm so as to obtain an area deviation and a rotation offset of the key forming position; and according to the area deviation and the rotation offset, carrying out quality evaluation on the soft package cigarette package. The accuracy and objectivity of cigarette packaging detection can be improved, and the product quality and the working efficiency of cigarette packaging are improved.

Description

technical field [0001] The invention relates to the technical field of cigarette package detection, in particular to a method and system for evaluating the molding quality of soft-wrapped cigarette packages. Background technique [0002] There are two forms of cigarette packaging: hard box packaging and soft packaging (including hardened soft packaging). Among them, soft packaging is widely used in low-grade, mid-grade, and high-end cigarettes. The quality of the packaging will directly determine the quality of cigarettes. Consumers' willingness to purchase affects the brand image of cigarettes. In GB5606-2005 "Cigarettes", relevant requirements are made for the packaging technology of soft-packed cigarettes. Now all cigarette companies have formulated corresponding internal standards in accordance with the national standards. The produced cigarette packs are evaluated for packaging molding quality, but there are problems such as low work efficiency, inconsistent manual det...
