Application background
From the structure, fisheye lens is indeed similar to fisheye structure and fisheye lens derived out two types, a known for circular image fisheye (circular fisheye), also called for full frame fisheye (full width fisheye). Circular fisheye is the originator of the fish eye lens, the design from the perspective of basic in more than 180 degrees, so screen can only see part of round, this kind of lens generally have oversized front lens group, and the lenses are bending of very large (to collect from more directions of light), the high, at present basically there have been very few manufacturers to produce a circular fisheye lens. This is mainly because of cost considerations.Key Technology
According to the characteristics of the fisheye lens imaging, suitable image distortion correction algorithm, the center and the radius of the fisheye image calibration, with calibration parameters are corrected, launch calibration modelmatlab
