Abstract

This application relates to the field of computers, especially the field of artificial intelligence, and provides a method, device, device, and storage medium for identifying document elements. Embodiments of this application can be applied to cloud technology, artificial intelligence, intelligent transportation, assisted driving, etc scene. The method includes: obtaining a large number of similar real document images by filling the element display area of ​​the corresponding document image template with new element data, and solving the problem of poor generalization of the model. In each round of training, based on the training sample set, two document images with the same document content and different image sizes are used for multi-scale prediction, combining the advantage of small-scale wide field of view with the advantage of large-scale boundary positioning to obtain The predicted recognition result of the first document image, and then use the predicted recognition result and the corresponding processed labeling result to adjust the model parameters, which solves the problem of inaccurate boundary recognition and improves the accuracy of the model's document element recognition.

Description

technical field [0001] The present application relates to the field of computers, in particular to the field of artificial intelligence, and provides a method, apparatus, device and storage medium for identifying document elements. Background technique [0002] In daily life, especially in work and office, it is often encountered that the downloaded files are in image format. Then, in order to obtain files in text format, it is necessary to use a document format conversion tool to realize the function of converting pictures to text. [0003] At present, the document element recognition algorithm of the document format conversion tool is used to identify the element display area of ​​each document element on the image, and then optical character recognition (OCR), natural language understanding and other methods are used to identify the text content of the corresponding area. . [0004] However, due to the low precision of the document element extraction method, when process...
