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 utilizing multiple colors. The method comprises the steps of converting to-be-stored information into a corresponding bit sequence according to an information storage rule; expanding the color types of the two-dimensional code pixel points; setting a code group corresponding to each color according to the total number of colors, and converting the bit sequence obtained by conversion into a corresponding code group according to a predefined format requirement; and converting the code group obtained by conversion into pixel points of corresponding colors according to a predefined code group and color correspondence rule, and forming a corresponding multi-color two-dimensional code. The invention provides a method for expanding the coding capacity of a two-dimensional code by using multiple colors. According to the technical scheme, under the condition that the number of the two-dimensional code pixel points is not changed, the number of the filling colors of the two-dimensional code pixel points is increased, the corresponding coding group is configured for each color, then the information storage amount of each pixel point is increased, and the increase of the total storage amount of the two-dimensional code information is achieved.

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...
