Abstract

The invention relates to a three-dimensional bar code encoding and decoding method and device. In the encoding process, by analyzing the file information in a computer, and by reading the computer language, the information is further compressed, encrypted and rearranged into a three-dimensional color bar code which can be recognized by a three-dimensional bar code recognition device, and the computer information is changed into the three-dimensional color bar code which can be printed onto a plane. In the decoding process, by acquiring the three-dimensional bar code tags on the plane and performing digital analysis on the acquired image, useful data included in the bar code can be solved, restoration is performed on the data by using a recognition program prestored in tag recognition device to solve the computer information included in the three-dimensional bar code, and the computer information is displayed directly through the recognition device. According to the invention, the information storage of the three-dimensional bar code can be increased, and the bar code error correcting capability can be improved.

Description

Technical field [0001] The invention relates to the technical field of information storage and security, in particular to a method and device for encoding and decoding a three-dimensional bar code. Background technique [0002] With the advancement of the information age, the functions of computers have become quite powerful, and the demand for information storage is also increasing. The original QR code can no longer meet the needs of computer users and barcode users due to the small amount of information storage. On the basis of the dimensional code, another dimension is added to obtain a three-dimensional bar code. The three-dimensional bar code can represent more data and has more information capacity, that is, any point in the space can be divided by the X axis, Y axis and Z axis. To describe the parameters, the concept of Z-axis layer height is introduced on the basis of the two-dimensional planar code determined by the X-axis and Y-axis, so that the coding capacity has bee...
