Distorted image correction method, device and equipment and computer readable storage medium

Abstract

The invention belongs to the technical field of image processing, and provides a distorted image correction method and device, computer equipment and a computer readable storage medium. In order to solve the problem that correction is inaccurate when flattening correction is carried out on a distorted image, an obtained initial distorted image is input into a preset first U-shaped neural network model included in a preset superposition U-shaped neural network model to obtain an image distortion disturbance field; and inputting the image distortion disturbance field into a preset second U-shaped neural network model included in a preset superposition U-shaped neural network model to obtain an image restoration disturbance field, and restoring the initial distorted image by using the image restoration disturbance field to obtain a corrected image. The image restoration disturbance field corresponding to the disturbance field for restoring the distorted image is directly predicted through the superposed U-shaped neural network model, and then the distorted image is restored by using the image restoration disturbance field to obtain the restored corrected image, so that the precision and accuracy of distorted image correction can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a distorted image correction method, apparatus, computer device, and computer-readable storage medium. Background technique [0002] Due to the ubiquity of mobile cameras, capturing images of documents is a common method for digitizing and recording physical documents. To make text recognition easier, it is often necessary to digitally flatten the document image as the physical document pages are folded or bent. In the traditional technology, the folded or curved image is generally flattened directly to obtain a corrected image. Since the folded or curved original image is directly flattened, there is a problem that the corrected image is inaccurate. SUMMARY OF THE INVENTION [0003] The present application provides a distorted image correction method, device, computer equipment and computer-readable storage medium, which can solve the technical problem...
