Activity mapping system
First Claim
1. A system for monitoring the activity of objects comprising:
- a detector arranged to receive radiation from a scene;
readout apparatus for monitoring and processing signals from the detector to identify objects meeting predetermined criteria appearing in the scene and to monitor the activity of identified objects within the scene; and
data processing and storage apparatus configured to compile statistical data over time indicating the occurrences of two or more object behaviours and to determine the distributions of the two or more object behaviours over respective contiguous areas defining all or part of the scene,wherein the system is configured to adjust a parameter against which one of the object behaviours is judged based on a contiguous area of another one of the object behaviours.

Abstract
A system for monitoring the motion of objects is configured to identify objects meeting predetermined criteria appearing in a scene and to track the motion of identified objects across the scene. In a particular embodiment the system is configured to compile statistical data for multiple points or regions to indicate one or both of: the frequency with which objects are initialised at that region or point; and the frequency with which initialised objects cross the region or point. The initialisation data will indicate the areas in the scene where objects are most frequently initialised. If the statistical data shows an area of the scene in which objects are never initialised this might indicate that there is an obstruction between objects that need to be tracked and the detector. The path data will indicate the paths most frequently followed by objects. If there is a particularly well trodden path to and fro in a particular part of the scene this might distort the result of a count of people entering and leaving a region in the scene.

7. A method for monitoring the operation of a system for monitoring the activity of objects, the system comprising a detector being arranged to receive radiation from a scene and readout apparatus for monitoring and processing signals from the detector to identify objects meeting predetermined criteria appearing in the scene and to monitor the activity of identified objects within the scene, the method comprising the following steps:
-
compiling statistical data over time indicating the occurrences of two or more object behaviours; determining the distributions of the one or more object behaviours over respective contiguous areas defining all or part of the scene; and adjusting a parameter against which one of the object behaviours is judged based on a contiguous area of another one of the object behaviours. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
