Invoice information identification method and device, computer equipment and storage medium

Abstract

The invention relates to an invoice information identification method and device, computer equipment, a computer readable storage medium and a computer program product, and the method comprises the steps: inputting a to-be-identified invoice image to a vertex positioning model after a server obtains the to-be-identified invoice image, inputting the to-be-identified invoice image to the vertex positioning model, and obtaining the to-be-identified invoice image; obtaining vertex coordinate information of an invoice information area of the to-be-identified invoice image; extracting the invoice information area according to the vertex coordinate information of the invoice information area; correcting the invoice information area based on the vertex coordinate information of the invoice information area; inputting the corrected invoice information area into an information box detection model to obtain coordinate information of each key text information box in the invoice information area; and extracting the key text information in the key text information box according to the coordinate information of the key text information box. According to the invoice identification method provided by the invention, accurate identification of key information in the invoice can be realized.

Description

technical field [0001] The present application relates to the technical field of big data processing, and in particular to an invoice information identification method, device, computer equipment, storage medium and computer program product. Background technique [0002] With the development of image processing technology, the use of information extracted from images for data statistics has been widely used. [0003] Taking the invoice as an example, the invoice is used as a reimbursement voucher, and the key information of the collected invoice image is identified through image processing technology, which can quickly realize subsequent reimbursement and accounting. In related technologies, when identifying the key information on the collected invoice images, it is mostly aimed at simple single-format invoices. [0004] However, in practical applications, different industries and different organizations use various formats of invoices, resulting in the problem of inaccurat...
