Abstract:
A method and apparatus acquires images of a scene with an omni-directional imager and a pan-tilt-zoom imager. A relationship between pixels in the input image and locations in the scene is expressed in terms of polar coordinates. An event is detected in the input images and the omni-directional pan-tilt-zoom camera is directed at the event in the scene using the relationship expressed in the polar coordinates.
