Abstract

The embodiment of the invention provides an image correction method, apparatus, device and system, a camera device and a display device. The method comprises: obtaining an image to be collected; based on a predetermined mapping relation, obtaining coordinates corresponding to coordinates of each pixel point in the image, and constructing the correction coordinates of each pixel point; and according to the correction coordinates of each pixel point, generating the correction image of the image. According to the embodiment of the invention, different distortion correction operations are not needed aiming at different distortions, and the coordinates of the pixel points in the image after correction distortion can be directly mapped through the predetermined coordinate mapping relation and the coordinates of the pixel points in the image to be corrected. the distortion correction operation can be simplified while effectively correcting the distortion so as to reduce the destroy degree of the distortion correction operation for the image information and reduce the calculation resource consumed by the distortion operation.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image correction method, device, equipment, system, camera equipment, and display equipment. Background technique [0002] In practical applications, many scenarios require the camera module to capture blackboard images (the blackboard is a writing surface that can be written repeatedly), convert the captured images into electronic documents, and display them on the display terminal. However, there are distortions in the image captured by the camera device, for example: radial distortion or tangential distortion caused by the inherent perspective distortion of the optical lens of the camera module, perspective distortion caused by the relative position between the camera module and the object to be photographed, and so on. However, related image processing techniques are difficult to effectively correct the distortion existing in the image. Contents of the i...
