Miniature two-dimensional code recognition method, device, readable storage medium and code scanning gun

Abstract

The invention is applicable to the technical field of two-dimensional code identification, and provides a miniature two-dimensional code identification method, a device, a readable storage medium and a code scanning gun. The miniature two-dimensional code identification method is used to identify the miniature two-dimensional code attached to the substrate, including: determining a target detection template suitable for the substrate from multiple detection templates according to a preset target template determination rule ; Wherein, the detection template is used to identify the information carried by the miniature two-dimensional code image, and each detection template is respectively suitable for identifying the miniature two-dimensional code image on the corresponding substrate; the micro two-dimensional code to be recognized with the target detection template The image is recognized. The present invention first determines the target detection template suitable for the base material from a plurality of detection templates according to the preset target template determination rules, and then uses the target detection template to identify the micro-two-dimensional code image, and there will be no detection template and In the event of a mismatch in the substrate material, accurate identification of the micro-QR code can be achieved.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code identification, and in particular relates to a miniature two-dimensional code identification method, device, readable storage medium and code scanning gun. Background technique [0002] Two-dimensional bar code (2-dimensional bar code) uses a specific geometric figure to record data symbol information. The geometric figure is distributed in black and white in the two-dimensional direction according to certain rules. The concept of the "0" and "1" bit streams uses several geometric shapes corresponding to binary to represent text and numerical information, which can be automatically read by image input devices or scanning guns to realize automatic processing of information. In modern commercial activities, two-dimensional codes can be used in a wide range of applications, such as: product anti-counterfeiting / traceability, advertising push, website links, data downloads, commodity trans...

Problems solved by technology

[0003] At present, the scanning and recognition technology for large-scale two-dimensional codes is relatively mature, but in some special fields, it is still necessary to recognize micron-level micro-two-dimensional codes on some specific materials. For example, artificial intelligence vision systems may involve metal materials or The micro two-dimensional code on the black plastic parts is used for identification. The existing two-dimensional code identification technology has limited accuracy and cannot accurately identify this micro two-dimensional code.
