Abstract

The embodiment of the invention discloses an electronic invoice information extraction method and an electronic device, which are used for realizing text recognition of a specified area of an added-value tax invoice so as to improve the invoice information recognition efficiency. The method provided by the embodiment of the invention comprises the following steps: selecting a value-added tax electronic invoice of a target type, selecting a standard picture as a reference picture, and manufacturing a user-defined identification template; importing the value-added tax electronic invoice file; performing preprocessing and geometric correction processing on the target value-added tax electronic invoice file, and performing scaling and cutting processing to obtain a unified standard size to obtain a processed value-added tax electronic invoice file; aligning the processed value-added tax electronic invoice file with the reference picture; carrying out ROI (Region Of Interest) cutting operation on a to-be-identified region corresponding to the template picture in the aligned picture to obtain an ROI intercepted region; performing identification operation on the ROI interception area to obtain an identification result; and then carrying out checking and structured processing, and outputting for storage in a specified format.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method for extracting electronic invoice information and electronic equipment. Background technique [0002] In daily work, the company's financial personnel have to deal with a lot of invoices every day, including electronic invoices, as well as paper value-added tax invoices, ordinary invoices, transportation invoices and so on. Manually entering invoices is not only time-consuming, but also error-prone; the dual storage of the original paper invoice and the scanned electronic version virtually adds a lot of workload to the financial staff. Therefore, the problem of bill automation processing still needs to be solved urgently. [0003] The traditional optical character recognition (Optical Character Recognition,) technical process includes the following five parts: input image, preprocessing, layout analysis, row and column cutting, character recognition, post-proc...
