Abstract

A video surveillance system is set up, calibrated, tasked, and operated. The system extracts video primitives and extracts even occurrences from the video primitives using event discriminators. The extracted video primitives and event occurrences may be used to create and define additional video analytic rules. The system can undertake a response, such as an alarm, based on extracted event occurrences.

Claims

1. An event detection method, comprising:

receiving a user input to a video surveillance system to put the video surveillance system into a configuration mode;

during the configuration mode, processing a first video portion to track an object in the first video portion by the video surveillance system;

using, at least in part, the tracking of the object in the first video portion to define at least one of an area of interest and a tripwire to create a first rule;

configuring the video surveillance system to detect an event in a second video portion using the first rule; and

after exiting configuration mode, performing video surveillance to detect the event in the second video portion using the first rule.

2. The method of claim 1, wherein tracking the object comprises tracking a human object in the first video portion.

3. The method of claim 1, wherein tracking the object comprises tracking a vehicle in the first video portion.

4. The method of claim 1, wherein tracking the object comprises tracking an emitter.

5. The method of claim 4, wherein tracking the object comprises outputting a radio frequency by the emitter.

6. The method of claim 4, wherein tracking the object comprises emitting location information.

7. The method of claim 4, wherein tracking the object comprises emitting GPS information.

8. The method of claim 1, wherein creating the first rule comprises determining the area of interest based on tracking the object.

9. The method of claim 8, further comprising creating the first rule to detect an object that enters the area of interest.

10. The method of claim 8, further comprising creating the first rule to detect a specific object that enters the area of interest.

11. The method of claim 10, wherein creating the first rule to detect the specific object that enters the area of interest comprises specifying a type of object with a user interface.

12. The method of claim 8, further comprising creating the first rule to detect loitering within the area of interest.

13. The method of claim 8, further comprising creating the first rule to detect an object that leaves the area of interest.

14. The method of claim 1, wherein creating the first rule comprises determining a location of the tripwire.

15. The method of claim 14, wherein creating the first rule comprises determining end points of the tripwire.

16. The method of claim 15, wherein determining an end point of the tripwire comprises detecting that the object has stopped when tracking the object.

17. The method of claim 8, further comprising creating the first rule to detect people entering a space.

18. The method of claim 14, further comprising detecting an orientation of the object.

19. The method of claim 18, wherein creating the first rule comprises determining a direction of the tripwire using the orientation of the object.

20. The method of claim 1, further comprising detecting an orientation of the object, wherein creating the first rule uses the detected orientation of the object.

21. The method of claim 1, further comprising detecting that the object has stopped,

wherein creating the first rule is responsive to the detection that the object has stopped.

22. The method of claim 1, wherein putting the video surveillance system into a configuration mode comprises use of a button, switch or remote control.

23. The method of claim 1, wherein tracking the object comprises tracking a tracker pattern in the first video portion.

24. The method of claim 1, wherein tracking the object comprises tracking a fiducial mark in the first video portion.

25. The method of claim 1, further comprising tracking a path of the object in the first video portion and using the path, at least in part, in creating the first rule.

26. The method of claim 1, further comprising tracking a speed of the object in the first video portion and using the tracked speed, at least in part, in creating the first rule.

27. The method of claim 1, further comprising detecting an event by analyzing the second video portion, at least in part, using the first rule.

28. An event detection method, comprising:

receiving a user input to a video surveillance system to put the video surveillance system into a configuration mode;

during the configuration mode, tracking by the video surveillance system an object in a first video portion with an emitter;

using, at least in part, the tracking of the object in the first video portion to define at least one of an area of interest and a tripwire to create a first rule; and

configuring the video surveillance system to detect an event in a second video portion using the first rule; and

after exiting configuration mode, performing video surveillance to detect the event in the second video portion using the first rule.

29. The method of claim 28, wherein tracking the object comprises outputting a radio frequency by the emitter.

30. The method of claim 28, wherein tracking the object comprises emitting location information.

31. The method of claim 28, wherein tracking the object comprises emitting GPS information.

32. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon, which, when executed by a processor, causes the processor to perform operations comprising:

putting a video surveillance system into a configuration mode in response to receiving a user input;

during the configuration mode, processing a first video portion to track an object in the first video portion;

using, at least in part, the tracking of the object in the first video portion to define at least one of an area of interest and a tripwire to create a first rule;

configuring the video surveillance system to detect an event in a second video portion using the first rule; and

after exiting configuration mode, performing video surveillance to detect the event in the second video portion using the first rule.

33. An video surveillance system, comprising:

at least one video camera;

a user interface; and

a computer configured to receive a user input via the user interface to put the video surveillance system into a configuration mode, to process a first video portion to track an object in the first video portion during the configuration mode, to define at least one of an area of interest and a tripwire to create a first rule using, at least in part, the tracking of the object in the first video portion, to configure the video surveillance system to detect an event in a second video portion using the first rule, and, after exiting configuration mode, to perform video surveillance to detect the event in the second video portion using the first rule.
