Embodiment Construction

[0069] At present, the main application scenario is to use the ID card reader to read the internal chip of the ID card to complete the identification of the citizen's ID card. However, the core chip of the card reader is expensive and the cost is relatively high. For this reason, the industry has proposed a scheme such as processing and identifying ID card images.

[0070] For example, in scheme 1, by collecting the ID card image, the collected ID card image is preprocessed, the preprocessed image is positioned and segmented, and the positioned and segmented image is recognized.

[0071] For another example, in scheme 2, the target ID card image is generated by preprocessing the initial ID card image to be recognized; according to the position distribution of the ID card information on the ID card, horizontal projection and vertical projection are performed on the target ID card image , performing character segmentation on the target ID card image according to the projection ...

Abstract

The invention discloses a certificate identification method and device, a computing device and a storage medium. The method comprises the steps of detecting at least one character block in a to-be-identified certificate image; identifying each character of the at least one character block to obtain a character identification result of each character block; matching the at least one character blockand the character identification result of each character block with layout structure information corresponding to the certificate image; and based on a matching result, determining element content corresponding to each certificate element of the certificate image. Therefore, adverse effects of light rays, backgrounds, segmentation errors and the like can be avoided, and support is provided for guaranteeing certificate identification accuracy.

Description

technical field [0001] The present application relates to the technical field of image analysis, in particular to a certificate recognition method, device, computing device and storage medium. Background technique [0002] An ID card is a document used to prove the identity of the holder, and is mostly granted to citizens by the governments of various countries or regions. As an important identity certificate, it plays a very important role in the actual life and job selection of citizens, for example, when citizens handle household registration, marriage registration, school enrollment, employment, notarization, going to border management areas, In the process of applying for exit procedures, etc., submitting identity documents is an indispensable and important step. [0003] At present, the main application scenario is to use the ID card reader to read the internal chip of the ID card to complete the identification of the citizen's ID card. However, the core chip of the ...
