Abstract
An image processing method includes: acquiring an image of a calibration board; acquiring a plurality of feature points in the image of the calibration board; evaluating a plurality of control parameters based on the feature points, the control parameters cooperatively defining a geometric curved surface that fits the feature points; and performing image correction on a to-be-corrected image based on the geometric curved surface to generate a corrected image.
