Certificate classification method, device and equipment

Abstract

The embodiment of the invention provides a certificate classification method, device and equipment. According to the scheme, the method comprises the following steps of: carrying out preliminary identification on an obtained certificate image by adopting a classification model to obtain a plurality of confidence scores for various certificate types, performing secondary comparison on the pluralityof candidate certificate types of which the confidence scores are greater than a first preset score and the to-be-identified certificate, specifically, respectively extracting a plurality of featurevectors of a mark region and a fixed character region in the plurality of candidate certificate types, and then extracting feature vectors of the mark region and the fixed character region in the to-be-identified certificate, and calculating the similarity between the first feature vector and the plurality of second feature vectors, and determining the candidate certificate type corresponding to the maximum similarity value as the type of the to-be-identified certificate in the plurality of obtained similarity values.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a certificate classification method, device and equipment. Background technique [0002] At present, with the development of Internet technology, online business processing has become more and more common. More and more businesses, such as communication industry, financial industry, entry and exit, etc., need to collect and register the user's certificate information to carry out Real-name system management. When identifying and authenticating documents, it is first necessary to classify the documents. However, with the development of science, technology and economy, the types of documents are gradually increasing, and it is more difficult to classify the documents. [0003] In the prior art, the multi-type certificate detection and classification model based on traditional machine learning classifies certificates. When faced with an increasi...

Problems solved by technology

When identifying and authenticating documents, it is first necessary to classify the documents. However, with the development of science, technology and economy, the types of documents are gradually increasing, and it is more difficult to classify the documents.

[0003] In the existing technology, the multi-type certificate detection and classification model based on traditional machine learning classifies the certificates. When faced with an increasing number of certificate types, the classification accuracy is low, which can no longer meet the needs of the market.
