Invoice recognition and authenticity verification method and system based on deep learning

Abstract

The invention discloses an invoice recognition and authenticity verification method and system based on deep learning, and the method comprises the steps: obtaining an invoice picture, and convertingthe invoice picture into Base64 coded invoice character data; inputting the invoice character data into a pre-trained two-dimensional code area positioning model to obtain coordinate information dataof the invoice; wherein the two-dimensional code area positioning model is obtained through pre-training of a convolutional neural network; cutting the invoice picture according to the coordinate information data of the invoice to obtain a two-dimensional code picture; identifying the two-dimensional code picture to obtain corresponding invoice data; sending the invoice data to an invoice checkingserver to obtain a authenticity checking result of the invoice. According to the method and the system, invoice authenticity verification and collection can be completed only by inputting invoice pictures, complicated manual input is not needed, automatic authenticity verification is achieved based on invoice picture recognition, automatic processing of the whole process is achieved, and the labor cost and the time cost are saved.

Description

technical field [0001] The present invention relates to the technical field of image recognition, and more specifically, to a deep learning-based invoice recognition verification method. Background technique [0002] The traditional paper invoice reimbursement process is cumbersome and has a long circulation cycle. There are many participants and the information of each participant is not interconnected. Paper invoices are faced with a large amount of data, repetitive operations, error-prone information input, and delays in business processing time, consuming a lot of human resources and time. However, under the current network environment, many local-level tax inspection systems have been launched, which has indeed brought convenience to the verification of the legality of invoices. [0003] However, the use of the online invoice inspection platform and the online verification of invoices are all done by manually entering relevant information. In the case of a large amount...
