Abstract

The invention discloses a detection and identification control method and system for an anti-counterfeiting two-dimensional code, and a storage medium, and the method comprises the steps: carrying outthe preprocessing of the anti-counterfeiting two-dimensional code through a space converter network when a two-dimensional code detection neural network detects that the anti-counterfeiting two-dimensional code exists in an image collected by an image collection device, and obtaining the preprocessed anti-counterfeiting two-dimensional code, wherein the anti-counterfeiting two-dimensional code isgenerated through an encoder network; decoding the anti-counterfeiting two-dimensional code after preprocessing through a decoder network, and extracting the data and anti-counterfeiting informationexpressed in the anti-counterfeiting two-dimensional code, wherein the decoder network is corresponding to an encoder network, and the anti-counterfeiting two-dimensional code which can be easily recognized by the decoder network can be generated through the encoder network; therefore, on the premise of ensuring that the anti-counterfeiting two-dimensional code is easy to identify, the safety of the anti-counterfeiting two-dimensional code is enhanced by adding the anti-counterfeiting information.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code application, and in particular relates to a detection and recognition method, system and storage medium of an anti-counterfeit two-dimensional code. Background technique [0002] At present, the two-dimensional code recognition technology is relatively mature, and users can use mobile phones, cameras or specific two-dimensional code recognizers to quickly locate and identify two-dimensional codes. However, in some specific occasions, such as in a dark environment, when the two-dimensional code is partially blocked, when a certain angle is formed between the two-dimensional code and the recognizer, or during the relative movement between the two-dimensional code and the recognizer, the two-dimensional The detection and recognition effect of the code recognizer on the two-dimensional code is often not ideal. [0003] Therefore, the problem that needs to be solved at present is to impro...
