Problems solved by technology

At present, there are two main ways to identify the text on the certificate: one is to manually recognize the text on the certificate by a special staff member, which is inefficient and the accuracy rate is unstable due to the influence of the staff's own state; the other One way is to use optical character recognition (Optical Character Recognition, OCR) text recognition technology to recognize the text on the certificate. The OCR text recognition technology specifically recognizes the text on the certificate through the photo of the certificate. Once a certain text appears The recognition error, when encountering the situation of recognizing the character again, the recognition of the character will still be wrong

Abstract

The invention relates to an identification method and device of certificate characters. The method comprises steps of acquiring a to-be-identified certificate picture; using a character region detection model to detect the to-be-identified certificate picture so as to obtain a character region of the to-be-identified certificate picture; using a character identification model to identify the character region of the to-be-identified certificate picture so as to obtain identified characters, wherein the character identification model and the character region detection model are obtained throughthe pre-training based on training samples in a database; when receiving the instruction of character identification errors after the identification confirmation of a user, receiving correct characters input by the user, using the correct characters as output results, adding a to-be-identified certificate picture into the training samples of the database by taking the correct characters as true marks, and updating the database; and based on the updated database, re-training the character region detection model and the character identification model.

Description

technical field [0001] The present application relates to the technical field of character recognition, in particular to a method and device for character recognition of certificates. Background technique [0002] In related technologies, with the advancement of science and technology and the development of society, certificates have become an indispensable part of people's lives. In the process of using the certificate, it is generally necessary to recognize the text on the certificate. At present, there are two main ways to recognize the text on the certificate: one is to manually recognize the text on the certificate by a special staff, which is inefficient and the accuracy rate is unstable due to the influence of the staff's own state; the other One way is to use Optical Character Recognition (OCR) text recognition technology to recognize the text on the certificate. The OCR text recognition technology specifically recognizes the text on the certificate through the phot...
