A method for generating two-dimensional color codes

Abstract

The invention relates to a method for generating a two-dimensional color code, comprising: replacing the original filling characters in the coded symbol data part of the two-dimensional code with all "0s" and regenerating the coded symbol; using a background image to mask the regenerated coded symbol Operation; obtain the replacement character at the corresponding padding position after the mask operation; replace the original padding character in the coded symbol data part of the two-dimensional code with the replaced character and regenerate the coded symbol again; use the background image to generate the coded symbol for the second time Perform another masking operation; on a two-dimensional dot matrix, print the functional symbols of the two-dimensional code and the coding symbols after the second masking operation according to the two-dimensional code specification. This two-dimensional color code generation method achieves reducing black or white code points by modifying the filling characters, so that it is easier to integrate into background patterns with various colors, improves the overall visual effect, and expands the commercial application range of two-dimensional codes.

Description

technical field [0001] The invention relates to image recognition and two-dimensional code technology, in particular to a method for generating a two-dimensional color code. Background technique [0002] A two-dimensional code is a black-and-white pattern distributed on a plane (two-dimensional direction) according to a certain rule with a specific geometric figure. From the appearance point of view, the two-dimensional code point is relatively large and basically fills the entire two-dimensional code area. If If you place the QR code image on the picture, the image area where the code area is located will be covered by the code image, which will affect the appearance of the image and the recognition efficiency. [0003] In addition, the black and white dots of the QR code represent 1 and 0 in binary respectively. In order to store data in the QR code, the data first needs to be encoded, and then evenly distributed to the code area of ​​the QR code according to the rules , ...

[0002] A two-dimensional code is a black-and-white pattern distributed on a plane (two-dimensional direction) according to a certain rule with a specific geometric figure. From the appearance point of view, the two-dimensional code point is relatively large and basically fills the entire two-dimensional code area. If Place the QR code map on the picture, and the picture area where the code area is located will be covered by the code map, which will affect the appearance of the picture and the recognition efficiency

[0003] In addition, the black and white dots of the QR code represent 1 and 0 in binary respectively. In order to store data in the QR code, the data needs to be coded first, and then evenly distributed to the code area of ​​the QR code according to the rules. , since there are a large number of uniform black and white code points in the code area, no matter whether it is a black base map or a white base map, there will be great interference
