Document table analysis method and device

Abstract

The invention provides a document table analysis method and device, and relates to the technical field of file analysis. The method comprises the steps of obtaining line segment feature information related to a table to be identified in a non-edited document, wherein the line segment feature information comprises coordinate information of line segments; obtaining horizontal line segment information and vertical line segment information in the to-be-identified table according to the line segment feature information; obtaining initial form information according to the horizontal line segment information and the vertical line segment information in the form to be identified; and generating an editable table corresponding to the table to be identified according to the initial table informationand the coordinate information of the line segments. By obtaining horizontal line segment information and vertical line segment information in a table to be identified through line segment feature information, obtaining initial table information according to the horizontal line segment information and the vertical line segment information, an editable table corresponding to the table to be identified is generated according to the initial table information and the line segment feature information related to the table to be identified. According to the method, the problems of high restoration complexity and poor restoration effect of the composite table and the missing table are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of document parsing, in particular to a document table parsing method and device. Background technique [0002] Portable document format PDF is an electronic file format, which has nothing to do with the operating system platform, that is, PDF files are universal whether they are in Windows, Unix or Apple's Mac OS operating system.
