Abstract

The invention relates to a table recognition method and device, a computer device and a storage medium. The method comprises the steps of obtaining a target document of which the document format is aPDF format; determining a table area where table content in the target document is located through a pre-trained table positioning model; cutting table content in the table area from the target document, and generating a corresponding table picture according to the table content; performing image recognition on the table picture, and determining characters in the table picture and position information of the characters; and generating a corresponding table file in a preset format according to the character and the position information. By adopting the method based on the image detection technology, the table data can be accurately extracted from the PDF document.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to a form recognition method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, more and more document formats have been developed and widely used, such as documents in PDF (Portable Document Format, Portable Document Format) format. Among them, PDF is a widely used electronic document format. Now more and more professional materials, e-books, product descriptions and e-mails are beginning to use PDF format documents. [0003] A document in PDF format is a document that cannot be directly edited, and many professional data are displayed in the form of PDF files. When it comes to tabular data, it is common to convert the table into an image in advance, and then embed the table image into the PDF document. PDF documents also have no special definition of tabular data, but only the combinatio...
