Three-dimensional (3D) image code generating and analyzing methods and device thereof

Abstract

The invention relates to 3D image code generating and analyzing methods and a device thereof, belonging to the technical field of image identification. The generating method comprises the steps that A) data numbers of information are obtained, and number system conversion and encoding are carried out on the data numbers to form coded data; B) according to a preset mapping table and the coded data, reference colors corresponding to different sub data units of a data area are determined, and the sub data units are filled with the corresponding reference colors; C) data values of different positioning units are obtained, reference colors corresponding to the different positioning units are determined according to the mapping table, and the positioning units are filled with the reference colors; D) an image area is filled with more than one image; and E) a positioning frame is added. An effective image frame is not included in the methods and device, the total effect is good, the quality of a colorized code is improved, and the methods and device can be suitable for different occasions. The cost is reduced, and certain economic benefits are provided.

Description

technical field [0001] The invention belongs to the technical field of image recognition; in particular, it relates to a method for generating and analyzing a three-dimensional image code and a device thereof. Background technique [0002] The identification code has gone through the development process of barcode, two-dimensional code and three-dimensional image code. [0003] A barcode is a graphic identifier that arranges multiple black bars and blanks with different widths according to certain coding rules to express a set of information. By connecting with the database on the network, it displays the information of the product corresponding to the barcode. A common barcode is a parallel line pattern formed by black bars (abbreviated as bars) and white bars (abbreviated as empty) with very different reflectivity. Barcodes can be connected to the database to mark the country of production, manufacturer, product name, production date, book classification number, mail sta...

Problems solved by technology

When such a color code is used in promotional materials, publications and packaging materials, it will affect its quality and effect, thereby reducing its value

And in the color code generation process, there is an extra process of adding an effective graphic frame, making it more complicated and increasing the cost

[0007] To sum up, the current color code cannot meet the requirements of the identification code on the carrying information capacity and the appearance of the identification code in the rapid development of advertising and life.
