Colorful three-dimensional code structure and colorful three-dimensional code reading method

Abstract

The invention provides a colorful three-dimensional code structure which at least comprises a code symbol structure formation module, a code symbol area division module and a code symbol information expression module, wherein the code symbol structure formation module is used for arranging three-dimensional codes into a square according to the capacity of to-be-stored data and displaying; the code symbol area division module is connected with the code symbol structure formation module, and is used for dividing the square three-dimensional codes, generated by the code symbol structure formation module, into a boundary positioning area and an internal information storage area; and the code symbol information expression module is connected with the code symbol area division module, and comprises a plurality of code symbol information expression units, and the code symbol information expression module is used for expressing the to-be-stored data by using the code symbol information expression units, and presenting the to-be-stored data into the three-dimensional codes.

Description

technical field [0001] The invention relates to the field of coding and reading of barcodes, in particular to a color three-dimensional code structure and a color three-dimensional code reading method. Background technique [0002] Traditional barcodes (such as figure 1 As shown) can only represent limited characters, which is only a kind of identification of the item, but cannot carry the description information for the item. Therefore, it must rely on the existence of the database during use, which greatly limits the application scenarios of the barcode. [0003] With QR (Quick Response, quick response) code (see Figure 2a ) as a representative matrix two-dimensional code uses rectangular blocks in a plane two-dimensional space to express information. Its information density is more than 20 times that of traditional barcodes, and the maximum information storage capacity can reach about 1KB. In order to further increase the storage density of barcodes, the following two ...

Problems solved by technology

The color 3D code with a capacity of more than 500 bytes occupies a large area, and it is prone to uneven illumination of each part of the code map, which will lead to a large reading error rate

[0008] In addition, the dilemma of color 3D codes is that the recognition of colors (more than 4 colors) is more easily affected by the light source. There is also a large area and prone to uneven illumination of various parts of the code map, which will lead to a large reading error rate
