The embodiment of the invention provides a detection method, device and equipment for structured information. The method comprises the steps of obtaining a file image of a to-be-identified file; determining a file type of the to-be-identified file based on the file image; performing structured detection on the file image to obtain field attributes of field information in the file image; and determining structured information included in the to-be-identified file according to the file type and the field attribute. According to the technical scheme provided by the embodiment, the file type of the to-be-identified file is determined through the obtained file image, the file image is subjected to structured detection, the field attribute of the field information in the file image is obtained, then the structured information included in the to-be-identified file is determined according to the file type and the field attribute, and the to-be-identified file is identified according to the structured information. The end-to-end structured information detection operation based on the image global semantic information is effectively realized, so that the detection quality and efficiency of the structured information are greatly improved.
Description
technical field [0001] The present invention relates to the technical field of information detection, and in particular, to a method, device and equipment for detecting structured information. Background technique [0002] With the rapid development of science and technology, the application of card tickets is more and more extensive. In order to improve the quality and efficiency of the application of card tickets, various card tickets can be applied electronically. The card ticket is subjected to an information recognition operation. In the prior art, the information recognition operation is usually realized by using Optical Character Recognition (Optical Character Recognition, OCR for short) technology, which specifically includes the following steps: detecting the text of the card ticket through a text detection model, Then, the relationship between the text blocks is extracted through a graph convolutional network (Graph Convolutional Network, GCN for short) combined wi...
