Abstract

The invention relates to the technical field of form recognition, specifically provides a form recognition method, and aims to solve the technical problems of poor generalization and poor accuracy of the existing form recognition methods. According to the method of the embodiment of the present invention, a preset image recognition model can be used to obtain the table line foreground map and the text foreground map of the form image to be recognized; the table structure of the table image to be recognized is obtained according to the table line foreground map; according to the position of the cell , the first text line position and the second text line position, to obtain the final text line position associated with the cell; according to the final text line position, the text line image corresponding to the associated cell is obtained from the table image to be recognized, and the text Perform text recognition on the row image and store the recognized text information into cells to form a recognized table. Through the above steps, the accuracy of table recognition can be improved, and the generalization is good.

Description

technical field [0001] The present invention relates to the technical field of form recognition, and in particular to a form recognition method, device and computer-readable storage medium. Background technique [0002] Tables are common content of text. It is often necessary to convert tables in images into editable file formats during work. Manual input is the easiest method, but this method is inefficient and error-prone when dealing with a large number of tables. At present, the more commonly used method is to use image acquisition equipment to obtain form images, and then use image features to extract form frame lines, such as text block features, form area logical relationship features, line intersection features, etc. to identify form images, and then output the recognition results. [0003] However, the above-mentioned recognition methods have a better recognition effect on clear or relatively simple form images, but are not effective in recognizing low-quality form ...
