Two-dimensional code positioning unit, modular two-dimensional code and information increasing and decreasing method

Abstract

The invention belongs to the technical field of two-dimensional codes, and particularly relates to a two-dimensional code positioning unit, a modular two-dimensional code and an information increasingand decreasing method. The two-dimensional code adopts a modular design. The two-dimensional code is composed of independent module units. The module unit is composed of a positioning unit and an information unit. Modularized design, According to the invention, the regular polygon module units are combined to realize the free customization of the two-dimensional code in the aspects of capacity, shape and the like, the plane of the whole two-dimensional code is formed according to the regular polygon module units of various rules, the splicing between the positioning unit and the information unit is convenient, and the two-dimensional code in any shape can be manufactured through artificial design, so that the difficulty of a modular two-dimensional code recognition algorithm is reduced. The number of the positioning units is only one, but the positions of the positioning units cannot be fixed, overall information such as positioning information, two-dimensional code capacity and checkcodes is stored in the positioning units, the number of the information units is multiple, and the information units are internally provided with serial numbers besides data and used for sorting theinformation units around the positioning units.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional codes, and in particular relates to a two-dimensional code positioning unit, a modular two-dimensional code and a method for increasing or decreasing information. Background technique [0002] The common two-dimensional code is to use a specific geometric figure according to a certain rule in the plane, that is, the two-dimensional direction, and the black and white graphics that are distributed in the two-dimensional direction record the data symbol information; in the code compilation, the " 0", "1" bit stream concept, using several geometric shapes corresponding to the binary to represent text and numerical information, and automatically read through image input equipment or photoelectric scanning equipment to realize automatic processing of information: it has the advantages of barcode technology Some commonalities: each code system has its specific character set; each character occupi...

AI Technical Summary

Problems solved by technology

[0003] The existing two-dimensional code is designed in one piece, the positioning point is fixed, and it is still lacking in scalability. The capacity and shape of the two-dimensional code are fixed. For example, the capacity of the common two-dimensional code is generally It is more than 500 Chinese characters. If it exceeds this capacity, the QR code cannot be used, which limits the use of the QR code.
