Embodiment Construction
[0061] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0062] In order to make the color information in the color two-dimensional image code contain effective information, rather than just bring a visual impact to people, the embodiments of the present invention provide a method and device for generating and reading a color identification type color two-dimensional image code.
[0063] The following first introduces a method for generating a color identification type color two-dimensional graph...

The embodiment of the invention discloses a method and device for generating and reading a color two-dimensional diagram code of a color identification type, and the method comprises the steps: obtaining to-be-coded original information; converting the to-be-coded original information into binary bit stream data, and grouping the binary bit stream data; putting each group of data into a to-be-embedded matrix according to a preset rule, and obtaining an initial data matrix; amplifying each element in the initial data matrix by a preset times, and obtaining a first pixel matrix; determining the colors corresponding to the elements in the first pixel matrix according to the preset corresponding relation of the elements and colors; putting the determined color into a data storage region of a to-be-generated color two-dimensional diagram code, and putting the feature information preset for the to-be-coded original information into the feature information region of a current color two-dimensional diagram code. The color information of the color two-dimensional diagram code generated through the method comprises effective original information, and brings more than visual impact.
Description
Technical field [0001] The invention relates to the field of two-dimensional graphic codes, in particular to a method and device for generating and recognizing color-marking color two-dimensional graphic codes. Background technique [0002] The research on two-dimensional graphic codes at home and abroad began in the late 1980s. A variety of code systems have been developed in the research of two-dimensional graphic code symbology, such as PDF417, QR Code, Code 49, etc. In real life, black and white two-dimensional graphics code is a more commonly used one. Specifically, it is encoded in a rectangular space through different distributions of black and white pixels in a matrix to record data information. Generally, it has a data storage area. And feature information area, where the distribution form of black and white pixels in the data storage area is used to store the data information that needs to be included in the two-dimensional code, and the feature information area is used...
