Square lattice anti-counterfeit label group, and method and system for reading square lattice anti-counterfeit label group

Abstract

The invention provides a square lattice anti-counterfeit label group, which is composed of a plurality of lattice anti-counterfeit figures arranged in order. A method for reading the square lattice anti-counterfeit label group comprises the following steps: performing gray level analysis on a label group image, and obtaining a corresponding code point group image; acquiring a dot pitch average value; generating the code point group image with a cell according to the dot pitch average value; dividing a plurality of lattice anti-counterfeit images with cells with the same dimension according to the dot pitch average value; determining a position of a locating shaft according to the dot pitch average value; and obtaining practical code value data of the square lattice anti-counterfeit label group by analyzing. A system for reading the square lattice anti-counterfeit label group comprises a label group image acquisition device, a gray value analyzer, a dot pitch average value acquisition device, a code point cell drawing device, a lattice anti-counterfeit image dividing device, a locating shaft position determining device and a practical code value data calculating device. The square lattice anti-counterfeit label group, and the method and system for reading the square lattice anti-counterfeit label group provided by the invention can obtain the authenticity information of the anti-counterfeit label by only adopting a smartphone or a tablet computer, and have the advantages of being convenient and fast.

Description

technical field [0001] The invention relates to an anti-counterfeit label, in particular to a square dot matrix anti-counterfeit label set, and a method and system for reading it. Background technique [0002] At present, in the existing anti-counterfeiting labels based on dot matrix images, it is only through a dedicated dot matrix reader that the authenticity information corresponding to the label can be identified. However, because the special dot matrix reader is relatively expensive and has a single function, generally only the product merchants who print the dot matrix image anti-counterfeiting label will have it, and ordinary consumers generally do not know the dot matrix reader. Reader to purchase. Since the number of product authenticity identification locations set up by product merchants for anti-counterfeit labels is limited and relatively scattered, it has caused a lot of inconvenience for consumers to verify the authenticity of anti-counterfeit labels.
