Problems solved by technology

Since machine readable codes are usually set on paper documents, when identifying the character content of machine readable codes, it may be affected by paper bending and deformation, resulting in inaccurate recognition of machine readable code character content
In addition, if the paper on which the machine-readable code is printed is photographed in advance, and the character content of the machine-readable code is recognized based on the photographed image, it may be affected by factors such as over-exposure, under-exposure, and blurred photographing, resulting in machine-readable errors. Code character content recognition is not accurate

Abstract

The embodiment of the invention provides a machine-readable code recognition method and device, electronic equipment and a storage medium. The method comprises the steps: acquiring a machine-readablecode image, wherein the machine-readable code image comprises a plurality of machine-readable code characters of the character content to be identified; detecting the position information of the machine-readable code character in the machine-readable code image in a single character position detection mode; calculating the confidence coefficient of the position information of the machine-readablecode character; determining a target machine-readable code character of to-be-corrected position information in the machine-readable code characters according to the confidence coefficient, and correcting the position information of the target machine-readable code character; and based on the corrected position information of the machine-readable code character, identifying the character content of the machine-readable code character.

Description

technical field [0001] This document relates to the field of computer technology, and in particular to a machine-readable code recognition method, device, electronic equipment and storage medium. Background technique [0002] In many scenarios, it is necessary to recognize the character content of the machine readable code. Machine readable code is also called MRZ (Machine Readable Zone) code. Machine-readable codes can be set on various documents, including but not limited to passports, Hong Kong and Macau passports, ID cards, etc. Since the machine readable code is usually set on a paper certificate, when the character content of the machine readable code is recognized, it may be affected by the bending and deformation of the paper, resulting in inaccurate recognition of the character content of the machine readable code. In addition, if the paper on which the machine-readable code is printed is photographed in advance, and the character content of the machine-readable c...
