Example Embodiment

[0032] The technical content of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0033] In order to meet the requirements of large-scale industrial production for production efficiency, identification code coded products such as crown caps and cigarette packaging boxes are all printed on large-format printing materials by special coding equipment such as inkjet printers and laser engraving machines. The large sheet of iron used in the crown cap and the large sheet of paper used in the production of cigarette packaging boxes are produced by batch printing or laser engraving (referred to as inkjet) with multiple identification codes, and then cutting. figure 1 This is an example of printing multiple QR codes in batches on the surface of large-format printing materials.

[0034] It usually requires multiple inkjet printers or laser engraving machines to engrave identification codes on large-format printed materia...

Abstract

The invention discloses a method for detecting identification code tagging quality of large-breadth printing material. The method includes the steps of reading the identification code on the surface of the large-breadth printing material through an identification code reader, conducting rejecting or shutdown processing if the reading failure number exceeds a predetermined threshold, further examining relevance between an internal code and an external code if the reading failure number does not exceed the predetermined threshold, determining that the identification code tagging is qualified if the internal code and the external code are relevant, and determining that the identification code tagging is unqualified if the internal code and the external code are irrelevant. The tagging quality problem of an identification code can be timely discovered during mass printing identification codes on the surfaces of the large-breadth printing material, thereby preventing batch waste products, substantially saving cost and improving production efficiency of identification code tagged products.

Description

technical field [0001] The invention relates to a method for detecting the coding quality of identification codes, in particular to a method for detecting the coding quality of identification codes when batch printing identification codes on the surface of large-format printing materials, and belongs to the technical field of machine vision. Background technique [0002] The popularization and application of the Internet of Things is inseparable from the automatic identification of identification codes (including but not limited to QR codes or digital codes, etc.). The identification code represented by the two-dimensional code has the characteristics of large data storage capacity and good confidentiality, and can be better combined with mobile terminals such as smart phones to form a good interaction and user experience. Therefore, the two-dimensional code is in widely used in today's society. People have successively proposed a variety of solutions for using QR codes for...
