IMAGE FORMING AND PROCESSING DEVICE AND METHOD FOR USE WITH NO MOVING PARTS CAMERA

摘要

A video surveillance system (10) has a camera equipped with a fisheye lens (20) having a substantially hemispheric field of view. The system implements operations equivalent to the panning, tilting and zooming of a conventional camera without the use of moving parts. The lens (20) is mounted vertically above a plane under surveillance. The camera produces a fisheye image (14) made up of a plurality of pixels. The fisheye image (14) is distorted due to the properties of the fisheye lens (20). The system corrects the distortion by mapping the pixels of the fisheye image (14) to coordinates produced by selecting a particular part of the fisheye to be viewed.
