specific Embodiment approach

[0099] Step S44-1: Determine the target corner position information of the target text image according to the corner position information of the text image and the preset aspect ratio for the text image.

[0100] Step S44-2: Determine correction parameters for the text image according to the corner position information of the text image and the target corner position information of the target text image.

[0101] In the above step S44-1, the preset aspect ratio refers to the desired aspect ratio of the target text image obtained after rectification. During the implementation of the present application, usually, the preset aspect ratio can be set as the standard aspect ratio of the text image without deformation. Taking the ID card image as an example, the standard aspect ratio of the ID card image is 300:190, so the preset aspect ratio can be set to 300:190. In this application, by setting the preset aspect ratio as the standard aspect ratio of the text image without deformat...

Abstract

The embodiment of the invention provides an image processing method and device, electronic equipment and a readable storage medium, and aims to reduce the error rate of a character recognition result.The method comprises the following steps: carrying out target area detection on a to-be-processed image to obtain a target area containing a text image on the to-be-processed image; cutting the to-be-processed image according to the target area containing the text image to obtain a sub-image containing the text image; carrying out corner point prediction on the text image in the sub-images to obtain corner point position information of the text image; determining a correction parameter for the text image according to the angular point position information of the text image, and performing projection correction on the text image according to the correction parameter to obtain a target text image after projection correction; and performing character recognition on the target text image to obtain character information in the image.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data processing, and in particular, to an image processing method, device, electronic device, and readable storage medium. Background technique [0002] With the development of image processing technology in the field of data processing, more and more users or enterprises begin to use image processing technology to recognize text in images, aiming to obtain text information in images. Taking the e-commerce business as an example, after the merchant uploads the photos of the business license and ID card to the e-commerce platform, in order to quickly enter the text information in the business license and ID card, the e-commerce platform usually uses the existing image processing technology to upload the photo to the merchant. Text recognition of the photos, and then manually check and correct the recognized text information, and finally save the checked and modified text informa...
