The invention discloses a method, device and equipment for generating structured information of characters in a picture and a medium. The method comprises the steps: transmitting a to-be-processed picture to a detection model, generating a plurality of sub-pictures containing the characters, enabling the plurality of sub-pictures to be constructed into a graph structure based on an recognition model, and enabling one sub-picture to correspond to one graph node in the graph structure; generating a feature vector of each graph node in the graph structure according to the recognition model, and generating a feature matrix of the graph structure by using the feature vectors of all graph nodes in the graph structure; According to the graph convolutional neural network, processing the feature matrix and the adjacent matrix of the graph structure to generate structured information of characters in the to-be-processed picture. According to the method, the sub-pictures containing the charactersare constructed into the graph structure, the feature matrix and the adjacent matrix of the graph structure are processed by the graph convolutional neural network model, and the structured information of the file in the to-be-processed picture is obtained, so that the accuracy of the generated structured information is ensured.
Description
technical field [0001] The present invention relates to the technical field of financial technology (Fintech), in particular to a method, device, equipment and medium for generating structured information of text in pictures. Background technique [0002] With the continuous development of financial technology (Fintech), especially Internet technology finance, more and more technologies (such as artificial intelligence, big data, cloud storage, structured information generation of text in pictures, etc.) are applied in the financial field, but The financial field also puts forward higher requirements for various technologies, such as requiring accurate recognition of text in ID pictures and formation of structured information. [0003] Currently, the structuring of ID pictures is often implemented using a series of rules, and different types of structuring tasks require the formulation of different rule sets, and a series of rules in the rule set are trivial and complicated,...
