Problems solved by technology

However, in recent years, the number font of ordinary invoices has changed a lot, and the printing has become lighter than before. As a result, the current tax self-service terminal system has greatly reduced the recognition rate of invoice numbers, making the original correct situation considered to be Wrong, the administrator intervened in maintenance due to false positives, which brought unnecessary troubles to taxpayers and hall staff, wasted time, and also made the self-service terminal lose its due meaning
Moreover, the general recognition algorithm has high requirements on the shooting environment of the terminal, so the debugging work of the shooting facilities of the terminal is greatly increased

Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] figure 1 In order to provide a system architecture for identifying invoice content provided by the embodiment of the present invention, one or more servers in the server cluster 101 train an initial object detection model. Here, the server 102 is used to train the initial target detection model as an example. The server 102 obtains the sample invoice image, processes the sample invoice image according to the image preprocessing a...

Abstract

The embodiment of the invention provides an invoice content identification method and device, and the method comprises the steps: a cloud server obtains an invoice image, and the invoice image is shot by a terminal and then is transmitted to the cloud server; the cloud server side processes the invoice image according to an image preprocessing algorithm, wherein the image preprocessing algorithm comprises a self-adaptive threshold method, a median filtering method and a mean filtering method; and the cloud server inputs the processed invoice image into a target detection model to obtain an identification result. According to the method, the acquisition of the recognition result can be accelerated under the condition of improving the accuracy. And the terminal sends the invoice image to the cloud server, and the invoice content is identified through the cloud server, so that the workload of debugging the terminal is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for identifying invoice content. Background technique [0002] The tax self-service terminal system is a platform device that integrates the window hardware of the tax service hall and the self-service operation software for taxpayers to handle their own taxes. The system realizes the basic related business functions, such as issuing special value-added tax invoices, issuing general value-added tax invoices, cargo transportation invoices, and tax declaration. The terminal installed with the tax self-service terminal system handles relevant taxes by itself, without having to wait in line at the lobby staff, which reduces the pressure on the lobby staff. In the current tax self-service terminal system, it is necessary to place paper invoices in the ticket box, such as issuing invoices and applying for invoices. In order to ensure that the database,...
