Abstract

The invention discloses a curved surface image restoration method, device and equipment and a readable storage medium, and the method comprises the steps: carrying out the preprocessing of a first curved surface two-dimensional code image after the first curved surface two-dimensional code image is obtained, and obtaining a second curved surface two-dimensional code image; carrying out plane perspective correction operation on the second curved surface two-dimensional code image to obtain a third curved surface two-dimensional code image; and performing curved surface restoration operation onthe third curved surface two-dimensional code image to obtain a planar two-dimensional code image corresponding to the first curved surface two-dimensional code image. According to the invention, theshot curved-surface two-dimensional code image caused by perspective distortion is restored into the planar two-dimensional code image through the planar perspective correction operation and the curved-surface restoration operation.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device, equipment and readable storage medium for restoring a curved surface image. Background technique [0002] With the development of smart phones and image processing technology, image QR codes based on different patterns, such as QRCode and Data Matrix, have been widely used in fields such as mobile payment, logistics and transportation, and product promotion. The two-dimensional code pattern used to carry information is usually square and displayed on a plane. When the image QR code is captured by the camera, the camera lens and sensor position are usually not parallel to the QR code image, resulting in an unknown shooting angle, resulting in the captured QR code image being different from the original QR code image There is a certain perspective distortion between them, and the shape, size and position of the captured QR code image and the original QR ...
