Table recognition method and device, computer equipment and storage medium

Abstract

The invention discloses a table recognition method and device, computer equipment and a storage medium. The method includes: through a shared feature extraction layer of the table recognition model, performing feature extraction for table objects on the to-be-recognized table to obtain a shared feature map; in the feature map extraction step, combining table line recognition and table content recognition together; after the shared feature map is obtained, enabling the table structure processing layer and the table content processing layer to analyze the shared feature map to obtain table line information and content detection frame information of the table to be recognized; on the basis of the content detection box information, identifying table content in a content detection box in the to-be-recognized table; based on the table line information, the content detection box information and the identified table content, forming the identified table corresponding to the to-be-identified table, so that organic combination of an independent table structure identification scheme and a table content identification scheme in related technologies is realized, the time required for table identification is shortened, and the table identification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a table recognition method, device, computer equipment and storage medium. Background technique [0002] Tables are a means of organizing data. People widely use various tables in communication, scientific research, and data analysis activities. In many cases, the form exists in the form of a non-editable image, such as a photo. In this case, it is necessary to use form recognition technology to convert the form in the image into an editable form file. [0003] At present, in related technologies, the table lines in the table are generally determined by table structure analysis methods such as traditional visual methods, and the table text is detected by text detection methods, and then table recognition is obtained based on the detection results of table lines and table text. As a result, in this scheme, the detection of table lines and text are two independent scheme...

[0003] At present, in related technologies, the table lines in the table are generally determined by table structure analysis methods such as traditional visual methods, and the table text is detected by text detection methods, and then table recognition is obtained based on the detection results of table lines and table text. As a result, in this scheme, the detection of table lines and text are two independent schemes, and the time required for table recognition is relatively long
