Abstract

The embodiment of the invention provides a method and a device for identifying table information in an image, electronic equipment and a storage medium. The method comprises the following steps: receiving a target image with a table; determining a table image containing a table from the target image; performing text line detection on the table image, and determining the position of a text line in the table image; recognizing the table image according to the position of the text line, and obtaining table information of the table image, wherein the table information comprises character information and table structure information. The table information obtained through recognition comprises the character information and the table structure information, and not only character content in the table, so that the diversity of table recognition results in the image is improved, and subsequent further processing such as table recovery is utilized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device, electronic equipment and storage medium for identifying table information in an image. Background technique [0002] In the field of image processing, there is an image including a table. In order to obtain the content of the table in the image, it is necessary to recognize the image including the table. [0003] At present, the recognition process of the form in the image is generally as follows: firstly extract the horizontal line and vertical line in the image, if there is no horizontal line and vertical line, it is determined that there is no form in the area; if there is a horizontal line and vertical line, the region growing method is used to determine the image The position of the table in the image, and then according to the position of the table in the image, perform text recognition on the table in the image, and obtain the text content in the...
