Problems solved by technology

However, due to the large number of types, it is difficult to have a unified recognition model
For example, the existing recognition model cannot perform layout analysis on table images without table lines, so that text recognition technology cannot be used to obtain relevant information for table images without table lines

Abstract

The invention discloses a form image layout analysis method and system, and the method comprises the steps: carrying out the image processing of a first image, obtaining a second image, enabling the first image to represent that at least a part of areas of the image have no form lines, and enabling the second image to represent a plain text image; performing image projection processing on the second image to obtain a projection result; analyzing the projection result based on a preset threshold to obtain table information; converting the first image based on the table information to obtain a target image, the target image representing a table image with a table line; and performing character recognition on the target image to obtain character information of the target image. Due to the fact that the table information is the row and column related data and the coordinate condition, the table image without the table lines in the partial area can be converted into the target image with the table lines, layout analysis can be conducted on the target image through the character recognition technology, and then character recognition of the table image without the table lines is achieved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a form image layout analysis method and system. Background technique [0002] As the important reference data of the enterprise, the financial statement data of the enterprise is usually entered manually, which will bring problems of low efficiency and high error rate. Therefore, the existing technology uses character recognition technology to solve the problems caused by manual entry. [0003] In terms of application scenarios, text recognition technology is generally divided into general recognition and layout recognition. General recognition is to simply extract all the text information in the image; layout recognition is to extract text information for images with a specific format, and to structure the data, that is, to clarify the meaning of the data in the target area. Table images, as a typical layout recognition scenario, have a large number of applicatio...
