Abstract

The present application discloses a method, system and device for verifying an image of a certificate to be recognized. The method process of an embodiment of the present specification includes: calling a current image acquisition device to shoot a target object, and obtaining multiple images of the certificate to be recognized under different postures and / or different illuminations of the target object; judging whether the image of the certificate to be recognized is valid , including: extracting the relevant information of the target object on the plurality of certificate images to be recognized for comprehensive analysis, identifying whether the certificate images to be recognized are remakes of the certificate images, and when the certificate images to be recognized are remakes of the certificate images , the document image to be recognized is invalid.

Description

technical field [0001] The present specification relates to the field of computer technology, and in particular, to a method, system and device for verifying an image of a certificate to be recognized. Background technique [0002] Optical Character Recognition (OCR) is a technology that analyzes and processes image files with characters to obtain text and layout information. Document text OCR refers to the use of optical character recognition technology to process the ID photo, so as to extract and identify the user information on the ID card (such as extracting the user name, birthday, certificate validity period and other information on the ID card photo). [0003] With the continuous maturity of document text OCR technology, in many application scenarios where document information needs to be entered, manual typing and input are abandoned, and the method of taking pictures of documents and using document text OCR technology to obtain document content is adopted. [0004...
