INTRUDER SITUATION AWARENESS SYSTEM
First Claim
Patent Images
1. A method for tracking one or more intruders in a building, comprising:
- detecting entry of an intruder into a building;
calculating bearing and speed of the intruder;
retrieving semantic information about the building;
calculating one or more potential paths of the intruder based on the semantic information about the building and on the bearing of the intruder;
calculating transit times between endpoints of the one or more potential paths based on the speed of the intruder and the semantic information about building that affect transit time along the one or more potential paths;
providing surveillance of the one or more potential paths at estimated times of presence on the one or more potential paths;
obtaining one or more images and locations of the intruder when available with one or more surveillance devices; and
/orproviding a situation awareness display from the one or more images when available of the intruder.

Abstract
An approach for detecting, tracking and capturing images of an intruder in a building. The intruder'"'"'s bearing and speed, and structural information about the building may provide at least a partial basis for calculating potential paths of the intruder. Cameras along the anticipated paths may be selected. These cameras may be optimized to cover nearly any area where the intruder may appear. Location, one or more images, and possibly other information may provide an intruder situation awareness for display.

13. An intruder situation awareness system for a building, comprising:
-
an intruder entry detector for a building; a bearing and heading detector; a building information model module; a module for calculating one or more potential paths of an intruder and estimated speed of movement of the intruder, connected to the bearing and heading detector and the building information model module; and a module for calculating transit times between endpoints of the one or more potential paths based on estimated speed of movement of the intruder. a plurality of cameras situated in the building, connected to the module for calculating the one or more potential paths and estimated speed of movement of the intruder; and wherein a set of cameras proximate to the one or more potential paths are selected from the plurality of cameras by the module for calculating one or more potential paths of an intruder and estimated speed of the intruder. - View Dependent Claims (14, 15, 16, 17, 18)

19. An intruder situation awareness system for tracking one or more intruders in a building, comprising:
-
a processor; an intruder entry detector connected to the processor; a building model module connected to the processor; a one or more potential intruder paths indicator connected to the processor; and a plurality of cameras connected to the processor; and wherein; the building model module contains structural information about the building; the one or more intruder paths indicator reveals paths that the intruder might take while moving about in the building; one or more cameras of the plurality of cameras are selected along the one or more intruder paths; and the processor computes intruder situation awareness information from the bearing and heading indicator, the building model module and the one or more cameras, to indicate likely locations of an intruder or intruders in the building. - View Dependent Claims (20)
