Sea & Sea S 12™1 Lens
A Nikonos V and Sea & Sea's 12mm full frame fisheye lens were used to take this reef panorama. The images are spectacular and the distortion unique but the circle effect becomes tiresome. Full frame fisheyes produce a flat, full image similar to that taken by a super wide angle lens. … Fetch This Document

Using Geometric Constraints For Fisheye Camera Calibration
Points are found with the following techniques: Circular imaging fisheye lens: A circular fisheye camera results from the size of the image plane charged coupled device (CCD) being larger than the image produced by the fisheye lens. Since the lens projects the scene with a circular symmetry, a circle … Read Here
