Abstract

A fisheye lens is a camera lens with a short focal length and a large field of view, which can shoot scenes with a viewing angle close to or even more than 180 degrees at one time. Due to its short focal length, large field of view, and constraints of optical principles, the images acquired by the fisheye camera have serious distortions and require geometric correction processing. In this paper, we use the method of transferring the optical center of the fisheye image to obtain the fisheye image after geometric correction in the left, middle and right perspectives, and stitch the three images together to achieve the fisheye image correction.
