Picture reconstruction method based on bill template

Abstract

A picture reconstruction method based on a bill template comprises the following steps: a bill text embedded network being constructed and trained, bill reconstruction parameters being input, a reconstructed bill picture being output, and the process being as follows: obtaining a filling text of each text area on the bill template from a dictionary, generating a text mask picture which is represented by a binary system and consistent in size for each text region, enabling the picture to have a filling text, enabling a text pixel value to be 1 and a background pixel value to be 0, cutting out atext background picture of each text region from the bill template, and enabling the text mask picture and the text background picture to be synthesized into a text reconstruction picture, and finally, pasting all the text reconstruction pictures back to the bill template, namely reconstructing the bill picture. And a user sets bill reconstruction parameters and a reconstruction number, and inputs the bill reconstruction parameters into the trained bill text embedding network to obtain an output reconstructed bill picture. The invention belongs to the technical field of information, and can reconstruct a large number of bill pictures attached to real bills based on bill templates.

Description

technical field [0001] The invention relates to a picture reconstruction method based on a bill template, which belongs to the field of information technology. Background technique [0002] Bills are an important part of modern life. Common bills include value-added tax invoices, train tickets, taxi invoices, toll invoices and voting, etc. Bills play an important role in people's lives as valid certificates for goods or services. [0003] Under the social situation of digital economic development, there is an imminent demand for automated bill detection and recognition applications in various fields. According to the survey, at present, value-added tax invoices and electronic invoices account for the vast majority of the large number of invoices and other documents that most enterprises face in economic activities such as transactions. At the current stage, the collection of bill information still adopts the traditional manual collection and entry method, and manual collect...

Problems solved by technology

This technical solution simulates the printing effect of a dot matrix printer, generates a character dot matrix of the given text based on the specified font, samples the dot matrix from the dot matrix to obtain the dot matrix printing effect, and adds actual printing defect effects such as printer stains and ink shortages , all the parameters about the text content information are provided by the user, and only blank images can be generated. When the user sets the background pattern, it will be tiled. The size of the generated image is determined by the circumscribed rectangular frame of the character, and the real bill contains many text groups. Distributed in various areas, so this technical solution cannot truly simulate the simulation generation of real bill pictures. In addition, the text effect printed by needle type and the actual printing environment effect added by pixel operation are not natural.
