Fluorescence 3D code generating method, identifying method, identifying device and system

Abstract

The invention discloses a fluorescence 3D code generating method, identifying method, identifying device and system. The generating method comprises the following steps: providing a carrier having a 2D plane matrix; printing 2D code on the 2D plane matrix of the carrier; adding a fluorescence material on a printed oil ink, and printing a third dimensional fluorescence array on the 2D plane matrix prior to or after printing the 2D code so as to enable the third dimensional fluorescence array and the 2D code overlap to form a plane figure of a fluorescence 3D code. According to the invention, the fluorescence 3D code generating method, through printing the 2D code and the third dimensional fluorescence array having the fluorescence material on the 2D plane matrix, enables the third dimensional fluorescence array and the 2D code to overlap so as to form the plane figure, and further, in accordance with needs, can acquire 3D codes of different fluorescence materials, ad has a large data capacity. In order to acquire a fluorescence signal of the fluorescence 3D code, UV light, purple light or blue light, green light laser light are required for the excitation, which can guarantee information safety and reliability.

Description

technical field [0001] The invention relates to the technical field of three-dimensional code information, in particular to a method for generating a fluorescent three-dimensional code, a recognition method, a recognition device and a system. Background technique [0002] Identification codes have experienced the development process of barcodes, two-dimensional codes and three-dimensional image codes. [0003] A barcode is a graphic identifier that arranges multiple black bars and white spaces with different widths according to certain coding rules to express a set of information. By connecting with the database on the network, it displays the information of the product corresponding to the barcode. A common barcode is a parallel line pattern formed by black bars (abbreviated as bars) and white bars (abbreviated as empty) with very different reflectivity. Barcodes can be connected to the database to mark the country of production, manufacturer, product name, production dat...

AI Technical Summary

Problems solved by technology

The solutions to increase the barcode size or increase the barcode density have their limitations: increasing the barcode size requires a larger printing area provided by the barcode carrier; increasing the barcode density requires printing equipment and reading equipment in terms of accuracy There are higher requirements, and it will reduce the anti-interference ability of the barcode, which greatly limits the use environment of the barcode

[0006] However, color is the third-dimensional information carrier of the 3D code, and the information carrier has a single form; the data information is represented by combined colors, which makes the data capacity limited, and the combined colors may have unclear boundaries, resulting in data information errors , Information security and reliability are poor, thus affecting the scope of use of 3D codes
