Example Embodiment

[0099] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In this application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A, B can be singular or plural. The character " / " generally indicates that the contextual objects are an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one item (piece) of a, b or c can represent: a, b, c, a and b, a and c, b and c or a and b and c, wherein a, b and c can be It can be single or multiple. It should be noted that "at...

Abstract

The invention discloses a table picture data analysis method and device and a storage medium. The method comprises the steps: obtaining a table picture, and carrying out the noise reduction and tilt correction of the table picture; position information of each cell in the table picture is calculated, and the cells are cut; and recognizing the character content in each cell, and carrying out associative storage on the character content and the cell position information. According to the table picture data analysis method, the table picture is obtained, the table picture is split into the single independent cell picture slices, character recognition is carried out on the cell picture slices, and the cell position information and the character information are correspondingly stored. Through the steps described by the method, the defect that structured information of a table is lost due to the fact that the function of a table frame line is ignored when the whole picture is integrally recognized in traditional image recognition is overcome. Therefore, when the picture with the table is analyzed, the structuralization degree is improved, and the data loss is reduced.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method, device and storage medium for analyzing form image data. Background technique [0002] In the fields of the Internet, industrial production or big data, it is often necessary to identify and analyze chart data in order to extract, store and utilize the data in the chart. In the existing image text recognition technology, when recognizing a picture containing a table, the entire picture is recognized as a whole, while the role of the border line of the table is ignored, and the structural information is lost, resulting in parsing data errors or data loss . [0003] For example, in the case of merging cells or multiple rows of data in the same cell, ignoring the table line may cause the cell data to be in the wrong row with other cell data; when the adjacent cell data is very close, There may be problems with data linking. Contents of the invention [0004] Th...
