Abstract--This paper presents a calibration procedure for a fish-eye lens (a high-distortion lens) mounted on
a CCD TV camera. The method is designed to account for the differences in images acquired via
a distortion-free lens camera setup and the images obtained by a fish-eye lens camera. The calibration
procedure essentially defines a mapping between points in the world coordinate system and their corres-
ponding point locations in the image plane. This step is important for applications in computer vision which
involve quantitative measurements. The objective of this mapping is to estimate the internal parameters of
the camera, including the effective focal length, one-pixel width on the image plane, image distortion center,
