Self-Calibration of Zooming Cameras from a Single Viewpoint
A configuration that commonly occurs in many imaging applications is that in which a camera has its optic centre fixed in location but which may rotate and zoom, thus changing its internal parameters. This is the case in applications such as surveillance, broadcasting and panoramic viewing, where a wide field of view is captured from a single viewpoint by rotating a camera which is typically mounted on a tripod or a pan-tilt platform and which may also be allowed to zoom.
