Abstract

The invention provides a table extraction method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a to-be-detected picture; identifying the to-be-detected picture to obtain a table area where a table is located in the to-be-detected picture; identifying the table area to extract table key points and generate an output matrix of the table key points; identifying the table area to extract structural information of the table; and generating a table according to the output matrix of the table key points and the structural information of the table. According to the method, table information does not need to be manually input, and the requirements for scanning and photographing are not high, so that the table extraction cost is low, the application range is wide, table key point detection is introduced to assist the structural information of the table in accurately reconstructing the table, and the accuracy of the generated table is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a table extraction method, device, computer equipment and storage medium. Background technique [0002] Tables are an effective means of organizing and arranging data composed of rows and columns. Its clear and visual communication mode makes it widely used in data analysis, scientific research and even public life. [0003] At present, there are usually two ways to convert paper printed forms into electronic forms: one is to manually enter the computer according to the style of the form; the other is to scan and take pictures of the paper printed forms, and then scan and take pictures on the computer to obtain Extract the table structure from the picture. However, the workload and cost of manual input are relatively large, and the requirements for scanning and photographing through computer processing are relatively high, and the applicability is poor.
