Abstract

The invention relates to the field of computers, in particular to the field of artificial intelligence, and provides a document element recognition method, device and equipment and a storage medium, and the embodiment of the invention can be applied to various scenes such as cloud technology, artificial intelligence, intelligent traffic and auxiliary driving. The method comprises the steps that a large number of similar real document images are obtained by filling new element data in an element display area of a corresponding document image template, and the problem that the generalization of a model is poor is solved. In each round of training, based on a training sample set, two document images with the same document content and different image sizes are used for multi-scale prediction, the small-scale wide-view advantage and the large-scale boundary positioning advantage are combined, and a prediction recognition result of the first document image is obtained. And the model parameters are adjusted by using the predicted recognition result and the corresponding processed labeling result, so that the problem of inaccurate boundary recognition is solved, and the document element recognition accuracy of the model is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to the field of artificial intelligence, and provides a document element identification method, device, equipment and storage medium. Background technique [0002] In daily life, especially when working in office, we often encounter the situation that the downloaded files are in image format. Then, in order to obtain the files in text format, we need to use a document format conversion tool to realize the function of converting images to text. [0003] At present, the element display area of ​​each document element on the image is identified through the document element recognition algorithm of the document format conversion tool, and then the text content in the corresponding area is recognized by methods such as Optical Character Recognition (OCR) and natural language understanding. . [0004] However, due to the low accuracy of the document element extraction method, when proc...
