Abstract

The invention relates to the field of data processing, and provides a method for identifying a table in a PDF document, which comprises the following steps: acquiring an original target page of the PDF document; when it is recognized that no conventional table exists in the original target page, or when the recognition result of the conventional table in the original target page does not meet a preset condition, recognizing whether a special table exists in the original target page or not through a special table recognition module, and the conventional table referring to a table with crossed lines; the special table being a table without cross lines, and the special table identification module is a module for identifying the table without cross lines. According to the method, the identification accuracy of the table in the PDF document can be improved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method and device for extracting tables in PDF documents. Background technique [0002] As we all know, Portable Document Format (PDF) has been widely used in various industries such as finance, IT, electronics and education. Every industry will accumulate a large amount of PDF documents, and these PDF documents record a large amount of information such as text, pictures, and tables.
