Problems solved by technology

However, the existing two-dimensional code design schemes only generate two-dimensional code patterns through the arrangement of small black and white squares, and this black and white two-dimensional code cannot be integrated with background patterns of different colors

Abstract

The invention provides a two-dimensional code generating method. The method comprises the steps of detecting color information of background patterns corresponding to the position of a coordinate position area of bit 0 data when writing in the bit 0 data, coloring the coordinate position area in a two-dimensional code grid where the bit 0 data are located with the color the same as the background patterns; when writing in bit 1 data, detecting color information of background patterns corresponding to the position of a coordinate position area of the bit 1 data, and coloring the coordinate position area in a two-dimensional code grid where the bit 1 data are located with the color similar to the color of the background patterns according to a predefined contrast threshold X and a reserved area percentage value Y. According to the two-dimensional code generating method, two-dimensional code patterns can be integrated into the background patterns with various colors, the overall visual effect is improved, and the two-dimensional code commercial application scope is expanded.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method for generating a two-dimensional code. Background technique [0002] Currently commonly used anti-counterfeiting technologies include barcode anti-counterfeiting, two-dimensional code anti-counterfeiting and so on. A barcode is a group of bar and space symbols arranged according to certain coding rules to represent information composed of certain characters, numbers and symbols. One-dimensional barcode is referred to as one-dimensional code. It is compiled into a series of characters composed of "0" and "1" according to the width of a group of horizontal bars. The binary characters are coded according to certain system conventions. . A barcode that stores information in a two-dimensional space in the horizontal and vertical directions is called a two-dimensional barcode (2-dimensional barcode), referred to as a two-dimensional code. In terms of...
