A generic camera model and calibration method for conventional, wide-angle, and fish-eye lenses

Fish- eye lenses are convenient in such applications where a very wide angle of view is needed, but their use for measurement purposes has been limited by the lack of an accurate, generic, and easy- to- use calibration procedure. We hence propose a generic camera model, which is suitable for fish- eye lens cameras as well as for conventional and wide- angle lens cameras, and a calibration method for estimating the parameters of the model. The achieved level of calibration accuracy is comparable to the previously reported state- of- the- art.
