Using Geometric Constraints For Fisheye Camera Calibration
For a dioptric (fisheye) camera, several lenses are used to reduce the incident angle of rays in order to project onto a CCD array with limited size. Figure 1 shows the layout of a fisheye lens (US Pat 4,412,726 designed by M. Horimoto at Minolta), generated by CodeV software [13]. … Retrieve Doc

LENS THEORY
The lens is oriented with the plano surface towards the focus and the origin (0 mm) is at the back vertex (V2) of the lens. The rays were launched parallel to the axis and equally spaced in a region 16 mm above and below the axis in a plane containing the axis (meridional plane). … Document Retrieval
