Abstract
This application provides a fisheye image processing method, an electronic device, and a computer-readable storage medium. The method includes: acquiring a fisheye image; generating a grayscale image according to the fisheye image; generating a first gradient image in a horizontal direction and a second gradient image in a perpendicular direction; generating an azimuthal image according to the first gradient image and the second gradient image; and determining an effective imaging area according to the azimuthal image. The anti-distortion correction for the fisheye camera is performed in the process of shooting images according to the effective imaging area of the fisheye camera, and thus the imaging area of the fisheye camera is accurately calibrated when the images are shot by the fisheye camera.
