Abstract

The invention relates to a positioning method and device for tables in a PDF document. The method comprises the steps that the PDF document containing the tables is received; character information andstraight line information are extracted from vector flow information of the PDF document; and according to the extracted character information and straight line information, a table region in the PDFdocument is positioned. According to the positioning method and device, table region positioning is performed based on all straight lines and text blocks in pages; and compared with the prior art, the accuracy of table region positioning can be improved, and consequently a basis is provided for accurate analysis of table information.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for locating tables in PDF documents. Background technique [0002] PDF documents are based on the PostScript language image model. For any printer, PDF can faithfully reproduce every character, color and image of the original. The characteristics that PDF has nothing to do with the operating system platform make it the most widely used ideal document format in electronic document distribution and digital information dissemination. [0003] Although the PDF document can accurately display the layout, the structural information in the PDF, such as the position information of the table, is not effectively recorded and stored, which makes it difficult to restore the table information in the PDF. The Chinese patent application with publication number CN105589841A provides a PDF document table recognition method, which uses the title feature and table line...
