ABSTRACT:
A video surveillance system has a camera equipped with a fisheye lens 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 is mounted vertically above a plane under surveillance. The camera produces a fisheye image made up of a plurality of pixels. The fisheye image is distorted due to the properties of the fisheye lens. The system corrects the distortion by mapping the pixels of the fisheye image to coordinates produced by selecting a particular part of the fisheye image to be viewed. This allows an operator to select parts of the field of view of the fisheye lens and view them as if they had been produced by a camera having a conventional lens being panned tilted or zoomed. The fisheye image formed by the camera is split into four separate image components carried by four bundles of optical fibers. Each bundle has a CCD and associated image processing circuitry which forms an electronic representation of the image component carried by that bundle.
