Definitions
- some or all channels may be multiplexed into one display, so that an operator views different areas by switching between channels.
- events may be completely missed simply because the relevant camera view picking up the event was not on the display or was not being observed at the time of the event.
- a surveillance system so configured that the moving masses for pan and tilt are minimal in order to enhance speed of scan and for the moving elements to be enclosed to prevent their observation.
- the system as a whole should preferably be potentially compatible with advanced, computer supported processing and display technology and be able to compete effectively in terms of operating costs and reliability with human operators.
- the reflector is formed to have a sufficient elevational field of view to not require movement and the reflector is only mounted for azimuthal rotation.
- the sensor may be rotated or translated. It is particularly convenient to utilise sensor translation to provide change in monitored elevation. This may be achieved by the reflector providing a larger field of view, at least in elevation, than the sensor area.
- the senor may comprise a group of sensors or a sensor having separately operable zones, and different areas may be activated instead of sensor movement.
- Figure 1 illustrates an embodiment of the invention having a fixed camera and moving plane mirror
- Figure 3 shows a further embodiment with a fixed camera and a . series of faceted mirrors
- Figure 4 shows another embodiment with a fixed camera and a single complex mirror.
- the detailed method by which such translation can be achieved is not, of itself, a feature of this invention.
- One method is to store each frame of image data in a digital frame store, and then to read out the data in the required staggered sequence to counteract the image rotation on the sensor and present an erect image to the viewer.
- the delays imposed by such processing are small and the final image is capable of presentation in a substantially real time basis.
- the multi-faceted mirrors may be rotated continuously at a high speed, and the nearest of the sensors angularly relocated to define an effective and required line of sight. Since the mirrors would under this condition be rotating, the corresponding images would describe a circle in the plane of the sensors, and it would be necessary to gate or strobe the selected sensor to produce a 'snapshot' of the image acceptably free from movement and blur.
- a strobe may eliminate the need for graphic rotation. Stroboscopic monitoring of the sensor may be provided within the graphics processor.
- Images from a mirror of this type may be difficult to comprehend directly as a display by an observer, but could be used by an automatic processing system to detect significant changes or movement in scene detail such as the advent of intruders. This may be achieved by automatic frame comparison techniques.
- a fast slewing mirror as described with respect to Figures 1 or 2 could then be quickly directed to the coordinates of any such disturbance to facilitate closer examination.
- the graphics processing device provides the signals to the fast slewing mirror and displays either the image from that mirror or a readout indicative of information relating to the frame comparison.
