Abstract

The invention provides a form analysis method based on character positioning recognition, and the method comprises the steps: inputting a form picture into a pre-trained character positioning network,and obtaining the position information of characters in the form picture; performing graph segmentation on the table picture according to the position information, segmenting a cell picture corresponding to the position information, inputting the cell picture into a pre-trained character recognition network, and performing character recognition to obtain cell character contents; extracting a first table layout of the table picture according to the position information; and generating a form file of the form picture according to the first form layout and the cell character content. According to the method, the established deep learning model can be used for positioning and identifying the characters in the table picture, and the table picture identification efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of computer processing, in particular to a table analysis method, medium and computer equipment based on character location recognition. Background technique [0002] At present, deep learning is developing rapidly in the field of image recognition. It has completely surpassed the accuracy and efficiency of traditional methods, and has attracted much attention in the field of image recognition. Deep learning is a new field in machine learning research. Its motivation is to establish and simulate the neural network of human brain for analysis and learning. It imitates the mechanism of human brain to explain data, such as images, sounds and texts. However, table recognition refers to converting the table in the table picture into editable table text, which requires text recognition and image recognition. [0003] In the existing technology, deep learning is also used to analyze the tables in the table picture...
