Abstract
A camera image processing subsystem processes image data corresponding to observations taken through a lens of focal point f using a spherical pin-hole model that maps the image data through a perspective center of a pin-hole prospective plane located within the lens onto a model sphere that is a focal length f in diameter and has its center at the perspective center of the pin-hole prospective plane. The subsystem models systematic distortion as rotation about coordinate axis of the pin-hole prospective plane, and maps all of the data, over the entire field of view of the lens, to corresponding spherical coordinates.
