Abstract

A video surveillance system is set up, calibrated, tasked, and operated. The system extracts video primitives and extracts event 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. A video surveillance system comprising:

a video sensor for receiving a video;

a processing unit for processing the received video;

a rule detector for creating a rule from the processed video;

an event detector for detecting an event of interest based on the rule; and

output means for outputting information based on the detected event of interest.

2. The system of claim 1, wherein the processing unit processes the received video to detect at least one trackable object.

3. The system of claim 2, wherein the rule detector creates the rule by observing the trackable object.

4. The system of claim 2, wherein the trackable object is at least one of:

a person;

a vehicle;

a watercraft in a water scene;

a light emitting diode (LED) emitter;

an audio emitter;

a radio frequency (RF) emitter;

an infrared (IR) device;

a prescribed configuration pattern;

or an object observable by the video sensor.

5. The system of claim 1, wherein the rule detector creates at least one of:

a tripwire, an area of interest (AOI), a direction, or a speed.

6. The system of claim 1, wherein the rule detector operates when the system is in a configuration mode.

7. The system of claim 6, further comprising:

an input mechanism, wherein the system is placed in the configuration mode with the input mechanism.

8. The system of claim 7, wherein the input mechanism is a component of the video sensor.

9. The system of claim 1, wherein the rule detector creates a default rule.

10. The system of claim 1, wherein the rule detector creates a rule from the processed video and at least one user input.

11. The system of claim 10, wherein the at least one user input includes at least one of:

an activity type, an object type, a time, or a date.

12. An apparatus for video surveillance configured to perform a method comprising:

receiving a video;

processing the received video;

creating a rule from the processed video;

detecting an event of interest in the video based on the rule; and

outputting information based on the detected event of interest.

13. The apparatus of claim 12, wherein processing the received video includes detecting a trackable object in the received video.

14. The apparatus of claim 13, wherein creating a rule comprises:

observing the trackable object and creating the rule based on the observation.

15. The apparatus of claim 13, wherein tracking the trackable object comprises tracking at least one of:

a person;

a vehicle;

a watercraft in a water scene;

a light emitting diode (LED) emitter;

an audio emitter;

a radio frequency (RF) emitter;

an infrared (IR) device;

a prescribed configuration pattern;

or an object observable by a video sensor.

16. The apparatus of claim 12, wherein creating a rule comprises:

creating at least one of a tripwire, an area of interest (AOI), a direction, or a speed.

17. The apparatus of claim 12, wherein the apparatus is configured to be placed in a configuration mode prior to processing the received video and creating the rule.

18. The apparatus of claim 12, wherein creating a rule comprises creating a default rule.

19. The apparatus of claim 12, wherein creating a rule comprises creating a rule from the processed video and at least one user input.

20. The apparatus of claim 19, wherein the at least one user input includes at least one of:

an activity type, an object type, a time, or a date.

21. A method of rule detection in a video surveillance system comprising:

receiving a video;

processing the received video;

creating a rule from the processed video;

detecting an event of interest in the video based on the rule; and

outputting information based on the detected event of interest.

22. The method of claim 21, further comprising:

entering a configuration mode prior to processing the received video;

detecting and observing a trackable object; and

creating the rule based on the observed trackable object.

23. The method of claim 22, wherein detecting the trackable object comprises detecting at least one of:

a person;

a vehicle;

a watercraft in a water scene;

a light emitting diode (LED) emitter;

an audio emitter;

a radio frequency (RF) emitter;

an infrared (IR) device;

a prescribed configuration pattern;

or an object observable by a video sensor.

24. The method of claim 21, wherein creating the rule comprises:

creating at least one of a tripwire, an area of interest (AOI), a direction, or a speed.

25. The method of claim 21, wherein creating a rule comprises creating a default rule.

26. The method of claim 21, wherein creating a rule comprises creating a rule from the processed video and at least one user input.

27. The method of claim 26, wherein the at least one user input includes at least one of:

an activity type, an object type, a time, or a date.
