Problems solved by technology

At present, the two-dimensional code recognition library on the market first needs to find three positioning frames. If the positioning frame is missing or the positioning frame is damaged, it cannot be recognized. Therefore, it is urgent to solve the problem of identifying the two-dimensional code when the positioning frame is missing.

Abstract

The invention relates to an opencv-based two-dimensional code recognition method for a missing positioning frame, including complete two-dimensional code positioning frame positioning, damaged two-dimensional code positioning frame positioning, damaged two-dimensional code positioning frame replacement and two-dimensional code identification. The positioning of the two-dimensional code positioning frame is used to determine the position of the complete two-dimensional code positioning frame; the positioning of the damaged two-dimensional code positioning frame is used to determine the position of the damaged two-dimensional code positioning frame; the replacement of the damaged two-dimensional code positioning frame It is used to replace the damaged two-dimensional code positioning frame with a complete two-dimensional code positioning frame and perform two-dimensional code recognition. The invention can improve the recognition rate of stained and damaged two-dimensional codes and two-dimensional codes with missing positioning frames.

Description

technical field [0001] The invention relates to the technical field of image restoration, in particular to a two-dimensional code recognition of a missing positioning frame based on opencv. Background technique [0002] Barcodes and QR codes are one or more types of graphics that arrange some relatively colored squares on a three-dimensional or flat surface to record certain information through a specific rule. This information can be text, images or voice. The law here draws on the concept of "0" and "1" executed inside the computer, and expresses the graphics with opposite colors as relative "0" and "1". The arrangement and combination of multiple color-relative squares here implies image coding When decoding the content, you only need to use some specific devices such as mobile phones, scanners, cameras, etc., and call the decoding program to automatically obtain the hidden content. Two-dimensional codes have some characteristics of barcode technology: barcodes of differ...
