Abstract

The invention discloses a certificate image character extraction method. The method comprises the following steps: S1, inputting a certificate image; S2, detecting a character position in the certificate image through a character detection model, and marking the character position through a marking box; S3, counting the position distribution condition of the marking box in the certificate image, judging the direction of the image and adjusting; s4, establishing a plane coordinate, merging and sorting the marking boxes in the same row according to the Y axis, and obtaining an information box ofeach row of characters; S5, aligning the standard template with the information box, outputting an intersection part of the information box and the standard template, and cutting and outputting a text picture; and S6, recognizing the character picture by using a character recognition model, and extracting the character content.

Description

technical field [0001] The invention relates to the fields of image processing and text recognition, in particular to a method for extracting text from a certificate image. Background technique [0002] Recognizing the text in the image of the certificate is very common and important in many scenarios. For example, in financial scenarios such as remote account opening, online lending, payment verification, etc., we need to identify the name, address, ID number and other information of the user ID card , to check whether the person and certificate are one; the law enforcement of the industrial and commercial department often needs to identify the business name, legal representative, and unified social credit code of the business license, and see whether the important information such as the company name, legal representative, and unified social credit code of the enterprise is consistent with the industrial and commercial department. The records in the database in the system ...
