Picture table recognition method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a picture table recognition method and device, electronic equipment and a storage medium, and relates to the technical field of image recognition. The method comprises: carrying out the segmentation of a table region, and obtaining a horizontal line segmentation grey-scale map, a vertical line segmentation grey-scale map, a row region segmentation grey-scale map and a column region segmentation grey-scale map; performing connected region analysis and clustering on the binarized horizontal line segmentation grey-scale map, the binarized vertical line segmentation grey-scale map, the binarized row region segmentation grey-scale map and the binarized column region segmentation grey-scale map to obtain a horizontal line segment object set, a vertical line segment object set, a row region pixel point set and a column region pixel point set; determining a plurality of cells according to the transverse line segment object set, the vertical line segmentobject set, the row region pixel point set and the column region pixel point set; and adding the text content extracted from the picture table into the cells. According to the method and device, theelectronic equipment and the storage medium provided by the embodiment of the invention, the table in the picture table can be accurately identified.

Description

technical field [0001] This document relates to the technical field of image recognition, in particular to a recognition method, device, electronic equipment and storage medium for a picture form. Background technique [0002] Image table recognition technology is mainly used to identify tables in pictures taken by mobile phones, other natural scene pictures or pictures converted from electronic documents. [0003] At present, for the recognition of picture tables, the table is often corrected first, so that the table lines in the image can basically be regarded as straight lines, and then the image recognition process is performed. [0004] However, when the table lines are bent, deformed, and the color is uneven due to external factors, the recognition effect of the table will be greatly reduced. Therefore, how to provide an effective solution to accurately identify the picture table is an urgent problem to be solved in the prior art. Contents of the invention [0005]...
