Embodiment 1

[0052] The embodiment of this application provides a method for extracting bill elements, such as figure 1 As shown, the method may include the following steps:

[0053] Step S101, identifying at least one to-be-recognized text area information of the image of the target bill;

[0054] Specifically, the target bill image is recognized through a corresponding image detection and recognition method to obtain at least one text region information to be recognized. Wherein, the target bill may be bills and documents such as invoices, warehouse receipts, and waybills.

[0055]Specifically, before the image of the target bill is recognized, the bill of the target image can also be preprocessed, such as binarization, denoising, tilt correction, color filtering, and the like.

[0056] Step S102, performing image recognition on the image corresponding to each area to be identified, and determining the text information corresponding to each area to be identified;

[0057] Specifically...

Abstract

The invention provides a bill element extraction method and device, electronic equipment and a readable storage medium, and is applied to the technical field of image processing, and the method comprises the steps: carrying out the image recognition of a bill image to determine a to-be-recognized text region, and carrying out the classification of the text information of the to-be-recognized textregion through a natural language understanding technology, and determining the type of the target bill, and then extracting element information of the target bill from the text information corresponding to the to-be-identified area based on the type of the target bill. Therefore, the automatic extraction of the bill element information is achieved, and the bill element extraction efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular, the present application relates to a bill element extraction method, device, electronic equipment and readable storage medium. Background technique [0002] With the development of the Internet, electronic office has become a trend. When the business personnel of an enterprise involve the transmission and management of bills in the process of handling business, they often convert paper bills into bill images for transmission or management, such as transferring bill images by mail, and classifying and saving bill images. When it is necessary to use the relevant elements of the bill, it is often necessary to extract the real relevant elements of the bill through manual reading, and the method of extracting the elements of the bill by manual reading has the problem of low efficiency. Therefore, how to quickly extract the elements of the relevant bill has become a p...
