Abstract

The invention discloses an image distortion correction method, device and equipment, and the method comprises the steps: obtaining a to-be-corrected image, and determining the pixel coordinates of a foreground object in the to-be-corrected image; determining at least one distortion correction grid corresponding to the pixel coordinates of the foreground object in a preset distortion correction network; wherein the size of the preset distortion correction network is the same as that of the to-be-corrected image, the distortion correction network comprises a plurality of distortion correction grids, and the plurality of distortion correction grids are overlapped and combined; and in the corresponding distortion correction grid, correcting the pixel coordinates of the foreground object according to a preset correction model to obtain the corrected pixel coordinates of the foreground object. The correction method has robustness and universality, through the preset correction model, the foreground object does not need to be segmented, the distortion state of the foreground object does not need to be judged, the image distortion correction performance is improved, and good visual experience is provided for a user.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an image distortion correction method, device and equipment. Background technique [0002] With the development of information technology, people's demand for camera of terminal equipment has increased sharply, which has promoted the rapid development of camera functions. The camera function of smart terminals including mobile phones and tablets has become more and more powerful, and has become one of the important functions of terminal equipment. . Among them, the field of view of the lens of the terminal device has a great influence on the camera function, but the larger the field of view of the lens, the more prominent the distortion problem of the camera image is. Contents of the invention [0003] The present invention provides an image distortion correction method, device and equipment. By performing image distortion correction on a preset distortion correction grid...
