Abstract
In this paper, we propose a method for calibration of a camera equipped with a new foveated wide angle lens. Because the lens has a nonlinear relationship between the incident angle and the distance from the center of the image, the pin-hole camera model is not applicable. External parameters are estimated using known reference points, observa-tion images and the lens characteristics. For evaluation of the calibration accuracy, we measure the three-dimensional position of an object by stereo vision using a combination of the camera equipped with the new lens and a pin-hole one. For comparison of the per-formance of the lens, the same method is applied to a set of a fish-eye camera and a pin-hole one.
