Abstract
An image distortion correction method and an apparatus, where the method includes: performing optical distortion correction on a collected source image to obtain a first corrected image, where the first corrected image includes a background region and a portrait in which stretching deformation occurs, and where the portrait in which stretching deformation occurs includes at least a first human body region in which stretching deformation occurs and a second human body region in which stretching deformation occurs; and performing algorithm constraint correction on the first human body region, the second human body region, and the background region to obtain a second corrected image, where constraint terms used for the algorithm constraint correction respectively constrain the first human body region, the second human body region, and the background region.
