Problems solved by technology

[0003] At present, QR two-dimensional codes are only encoded in black and white. Although there are also colored two-dimensional codes, which have all the functions of ordinary black and white two-dimensional codes, and can also present a colorful appearance, but the capacity of colored two-dimensional codes is not large. Add, just use dark and light colors to encode, essentially no difference from black and white QR codes
[0004] At present, the resolution capability of mainstream code scanning devices is limited. Expanding the capacity by increasing the pixels of two-dimensional codes puts too much pressure on the code scanning devices, making it difficult to popularize and apply them. Under the same circumstances, the method of increasing the storage capacity of the two-dimensional code

Abstract

The invention discloses a method and a device for expanding the coding capacity of a two-dimensional code by using multiple colors. The method includes: converting the information to be stored into a corresponding bit sequence according to information storage rules; expanding the color types of two-dimensional code pixel points; setting the coding group corresponding to each color according to the total number of colors, and converting the bit sequence obtained The sequence is converted into a corresponding code group according to the predefined format requirements; the converted code group is converted into pixels of the corresponding color according to the predefined code group and color correspondence rules, and a corresponding multi-color QR code is formed . The method for expanding the coding capacity of two-dimensional codes provided by the present invention can expand the number of filling colors of two-dimensional code pixels under the condition that the number of pixels of two-dimensional codes remains unchanged, and configure corresponding colors for each color. Encoding groups, and then expand the information storage capacity of each pixel, and realize the increase of the total amount of two-dimensional code information storage.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code preparation, in particular to a method and device for expanding the encoding capacity of two-dimensional codes by using multiple colors. Background technique [0002] QR code, also known as QR Code, QR stands for Quick Response, is a very popular coding method on mobile devices in recent years, and it can store more information than traditional Bar Code barcodes. The more common QR two-dimensional code is square, with smaller square patterns like the word "Hui" printed on the three corners. [0003] At present, QR two-dimensional codes are only encoded in black and white. Although there are also colored two-dimensional codes, which have all the functions of ordinary black and white two-dimensional codes, and can also present a colorful appearance, but the capacity of colored two-dimensional codes is not large. Addition, just use dark and light colors to encode, which is essentially t...
