Abstract

The invention provides a two-dimensional code generating method and device. The method includes determining data information stored in a to-be-generated two-dimensional code; determining the template, the error correction level which is the proportion of error correcting codeword in the total codeword and the gray level of the to-be-generated two-dimensional code, determining the binary code of each gray level; according to data information and the error correction level, generating first codeword flow including data codeword flow obtained through conversion of data information and error correction codeword after the data codeword flow; adding codeword in the first codeword flow into data and error correction information code parts in the template in sequence and generating the gray level two-dimensional code storing the data information according to the binary code corresponding to each gray level. By adopting the above method, two-dimensional code storage space can be expanded and more data information can be stored in the two-dimensional code of the same version and specification.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to a method and device for generating two-dimensional codes. Background technique [0002] The so-called two-dimensional code is to arrange data information on a plane according to certain rules through black and white geometric figures. In the whole code compilation, the binary bit stream idea of ​​computer science is used to complete the expression function of data information by matching certain geometric figures with binary codes, and then use the peripheral photoelectric detection equipment to complete the automatic identification and processing of graphic information Features. Since each code system of the two-dimensional code has its specific character set, each character occupies a certain width, has a certain verification function, automatically recognizes information in different lines, and handles graphic rotation changes, etc., therefore, you can use two-d...
