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.

Image splitting forming and processing device and method for use with no

A surveillance device having a camera and lens assembly in which a condition of the assembly is controllable by a movable part and in which a closed loop digital motion control system is used to control the movable part and, therefore, the condition. The closed loop motion control system includes a dedicated digital signal processor which is used exclusively to control the movable part. The digital motion control system also includes a drive motor which is responsive to the digital signal processor and a digital encoder which monitors the position of the movable part and provides encoded position signals to the processor. Movable parts for the pan and tilt assemblies of the surveillance device are controlled by separate closed loop motion control systems each having its own dedicated digital signal processor.

Surveillance apparatus with enhanced control of camera and lens assembly

A method for determining the speed of a vehicle using a camera. The method automatically compensates an apparent speed determination for inaccuracies due to the position of the camera with respect to the vehicle. The invention also includes a method for calibrating a camera to compensate for inaccuracies due to the position of the camera.
