Abstract

The invention relates to the technical field of automatic identification, and discloses a generation method, a generation device, an identification method and an identification device of a dynamic three-dimensional code. The generation method comprises the steps: carrying out the coding according to the preset embedded information, and obtaining a three-dimensional code threshold layer; adding color information and / or gray scale information to the three-dimensional code threshold layer to obtain a visual code layer; carrying out re-coding on the visual code layer to obtain a three-dimensionalcode picture; carrying out fusion processing on the three-dimensional code picture and more than one frame of background picture to obtain a fused three-dimensional code. The information capacity is larger, and the forms are more diversified and the user experience is better on the basis of ensuring the recognition efficiency and accuracy. Particularly, a plurality of dynamic three-dimensional codes can be superposed to form a three-dimensional code group, so that the management and the use are more convenient.

Description

technical field

[0001] The invention relates to the technical field of automatic identification, in particular to a method for generating a dynamic three-dimensional code, an identification method and a corresponding device. Background technique

[0002] The unique identification code is the key to connect the real physical world and the virtual information world. Combined with the management of the corresponding information system, it can be used to uniquely mark specific objects and their holders. It mainly includes the following four types:

[0003] 1. Radio frequency identification code (RFID), which uses radio frequency signals to achieve non-contact information transmission through spatial coupling (alternating magnetic field or electromagnetic field) and achieves the purpose of identification through the transmitted information. It usually consists of three parts: Tag (Tag): composed of Composed of coupling elements and chips, each tag has a unique electronic code, wh...
