Abstract

The invention discloses a packaging decoration quality inspection method based on machine vision, and the method comprises the steps: collecting a first product decoration image through a first image sensor, inputting the first product decoration image into a first preprocessing module, and obtaining a first image set; sequentially performing feature extraction on the first image set to obtain a first image feature set; obtaining a first display surface according to the first product; constructing a first plane-coordinate system based on the first display surface, and obtaining first image position identification information; obtaining a first evaluation result based on the first decoration quality evaluation model; obtaining a first evaluation threshold value, and judging whether the first evaluation result meets the first evaluation threshold value or not; and when the first evaluation result meets the first evaluation threshold value, marking first qualified label information on the first product decoration image. The technical problems that in the prior art, the inspection efficiency of product packaging materials and printing decoration quality is low, and meanwhile mistaken inspection and missing inspection exist are solved.

Description

technical field [0001] This application relates to the field of artificial intelligence, in particular to a machine vision-based packaging and decoration quality inspection method. Background technique [0002] Sales packaging and transportation packaging have different tasks in commodity circulation. Transportation packaging mainly acts as a bridge between production and sales, while sales packaging mainly acts as a medium for sales and consumption. Sales packaging and decoration is an advertisement that can be seen everywhere in the market. It is a tool to directly convey information to existing and potential markets, a powerful weapon to improve the competitiveness of commodities, and a typical way to promote marketing. A successful sales package will undoubtedly have a huge effect on increasing sales and increasing prices. In actual production, the quality inspection of packaging and decoration is often carried out manually, which takes a long time and has low inspectio...
