Dot-matrix two-dimensional code coding and decoding

Abstract

The invention belongs to the technical field of information storage and identification, and provides a two-dimensional code coding and decoding scheme. A dot-matrix two-dimensional code is a matrix two-dimensional code formed by solid dots and blank dots which are arranged according to a two-dimensional matrix mode. The dot-matrix two-dimensional code is composed of a head border area, a tail border area, a start area, an end area and a data area. The data area is arranged in the middle position of the two-dimensional code. The head border area is arranged at the upper end of the data area, the tail border area is arranged at the lower end, the start area is arranged at the left side and the end area is arranged at the right side. The dot-matrix two-dimensional code is suitable for coding machine and printing output so that a problem that the two-dimensional code is not suitable for automatic assembly line output can be solved.

Description

technical field [0001] The invention belongs to the technical field of information storage and identification, and is a coding and decoding scheme of a two-dimensional code. Background technique [0002] At present, the two-dimensional code has been well applied in various fields, such as logistics, anti-counterfeiting, information access, advertising push, commodity trading, electronic vouchers, etc. The two-dimensional code has the advantages of fast recognition speed, low bit error rate and large information storage capacity. advantage. [0003] Currently, there are about ten kinds of QR codes commonly used, such as QR code, DM code, Code49 code, Code16K code, PDF417 code, CP code, Tianzi code, CodeOne code, Aztec code, etc. Although these two-dimensional codes use Data error correction technology is used to ensure the integrity and reliability of data, but the requirements for printing QR codes are relatively high. In today's industrialized and information society, fact...

Problems solved by technology

[0003] Currently, there are about ten kinds of QR codes commonly used, such as QR code, DM code, Code49 code, Code16K code, PDF417 code, CP code, Tianzi code, CodeOne code, Aztec code, etc. Although these two-dimensional codes use Data error correction technology is used to ensure the integrity and reliability of data, but the requirements for printing QR codes are relatively high. In today's industrialized and information society, factory production is basically based on automatic assembly lines. The general-purpose equipment for outputting codes on commodities is a coding machine. With the advancement of technology, the resolution of many coding machines outputting codes is getting higher and higher, and can print one-dimensional barcodes and two-dimensional barcodes, but this is at the expense of printing The speed of the code is at the expense of the speed of the code, and the automatic assembly line is running at high speed, so it is difficult to see which factory uses a coding machine to print a one-dimensional barcode or a two-dimensional barcode on the assembly line. It is common to use a coding machine to print out Characters, the content is generally the product batch number, inspection qualification information, etc., because the characters output by the coding machine are not consistent and have obvious dot matrix characteristics, it is difficult to use the OCR system to identify
