Problems solved by technology

[0006] The key to the inability of two-dimensional barcodes to be widely used in my country is that the core technology has been registered as a patent by foreign manufacturers. Even if we produce and process according to international standards, we must pay considerable patent fees, which restricts the use of this very good technology in our country. the popularity of
The reason is that the foreign two-dimensi

Embodiment 1

[0078] 1. Structure description:

[0079] Unit block: The most basic unit of the two-dimensional barcode DZ-Code is a square block (also called a point, a unit block, or a rectangular color block unit). The color of each point is allowed to be two predefined colors (colorA, One of colorB), which means 0 or 1 in binary. See figure 1 .

[0080] Unit information block: One level larger than the unit block, it is a larger rectangle (or square) composed of several points (unit blocks), called a unit information block, each unit information block consists of two parts, one part Is the data area, part of which is the location identifier. DZ-Code can be composed of several unit information blocks, such as 3×3, 4×4, 5×5, and all the examples in this article are 4×4. See figure 2 .

[0081]Positioning identifier: The positioning identifier is composed of the leftmost column of points and the bottom row of points in the unit information block. According to the position of the unit...

Abstract

The invention discloses a matrix two-dimensional bar code and coding and decoding method, which is characterized by the following: the code graph of bar code is composed of gapless arrangement ní‡m rectangle unit information blocks, wherein m and n is positive integral more than 1; n is different from or the same as m; each rectangle unit information block is composed of gapless arrangements n'í‡m' of different optical characters with two rectangle colorful blocks, wherein n' and m' is positive integral more than 1; n' is different from or the same as m'; each rectangle unit information block contains location ID character and data region; the shape of ID character displays L type or inversed L type along two adjacent edges of rectangle unit information block frame. The bar code contains the following characters: large capacity, high error-correcting rate, high pollution-proof and distortion-proof ability, multiple language editing codes, separating coding and decoding code, random scale adjustment and omnibearing recognizing, which can be applied in multiple domains.

Description

technical field [0001] The invention belongs to the technical field of barcodes, and relates to a matrix type two-dimensional barcode and an encoding and decoding method thereof. Background technique [0002] Bar code technology is an automatic identification technology formed in the practice of computer application. It is an emerging technology developed on the basis of computer technology and information technology that integrates coding, printing, identification, data collection and processing. [0003] Since its appearance in the 1970s, one-dimensional barcodes have attracted widespread attention and developed rapidly. They are widely used in the fields of commercial circulation, warehousing, medical care, library information, postal services, railways, transportation, and production automation management. Its use has greatly improved the speed of data collection and information processing, improved work efficiency, and made great contributions to the scientific and mode...
