Abstract

A system and method for detecting human intruders while rejecting/ignoring an occupant'"'"'s registered pet. An object detection system is configured to detect an object that is present in a monitored area and generate a signal output relative to the type of object. A signature processor is configured to receive the generated signal output and produce an object signature, and compare a threshold signature to the object signature, wherein the threshold signature is generated using a photograph of a reserved object, and wherein the object detection system rejects the detected object when the object signature is determined to be similar to the threshold signatures.

Claims

1. A system comprising:

an object detection system configured to detect an object that is present in a monitored area and generate a signal output representative of the type of object; and

a signature processor configured to;

receive the generated signal output and produce an object signature; and

compare a threshold signature to the object signature,

wherein the threshold signature is generated using a photograph of a reserved object, and

wherein the object detection system rejects the detected object when the object signature is determined to be similar to the threshold signature.

2. The system of claim 1, wherein the signature processor compares a peak amplitude of the threshold signature to a peak amplitude of the object signature to determine whether the object is the reserved object or an unauthorized object.

3. The system of claim 2, wherein the object detection system comprises:

a sensor configured to detect the presence of the object in the monitored area and produce a sensor signal; and

a sensor processor configured to generate the signal output based on the sensor signal.

4. The system of claim 3, wherein the sensor is a motion sensor.

5. The system of claim 4, wherein the sensor is a passive infrared (PIR) sensor.

6. The system of claim 2, wherein the photograph is a picture of an occupant'"'"'s pet.

7. The system of claim 6, wherein estimated characteristics of a part from the photograph are used to generate the threshold signature.

8. The system of claim 2, further comprising a service provider server configured to:

estimate characteristics of the reserved object in the photograph;

generate the threshold signature using the estimated characteristics; and

forward to the object detection system the threshold signature.

9. The system of claim 8, wherein the service provider server is further configured to retrieve from a pattern database a pattern signature that is associated with an object having similar characteristics as the estimated characteristics, wherein the retrieved pattern signature is the threshold signature.

10. The system of claim 9, wherein the estimated characteristics include one or more of height, weight, length, type of object, and hair length.

11. The system of claim 9,

wherein the pattern database includes a plurality of pattern signatures, each pattern signature associated with an object having object characteristics, and

wherein the threshold signature is generated based on a selection of the pattern signature having objects characteristics similar to the estimated characteristics.

12. The system of claim 8, wherein the reserved object in the photograph is an occupant'"'"'s pet.

13. A method comprising:

detecting an object that is present in a monitored area;

generating a signal output representative of the type of object;

generating an object signature based on the signal output; and

comparing a threshold signature to the object signature,

wherein the threshold signature is generated using a photograph of a reserved object, and

wherein the object detection system rejects the detected object when the object signature is determined to be similar to the threshold signature.

14. The method of claim 13, further comprising comparing a peak amplitude of the threshold signature to a peak amplitude of the object signature to determine whether the object is the reserved object or an unauthorized object.

15. The method of claim 14, wherein the photograph is a picture of an occupant'"'"'s pet.

16. The system of claim 15, wherein estimated characteristics of the part from the photograph are used to generate the threshold signature.

17. The system of claim 14, further comprising:

estimating characteristics of the reserved object in the photograph;

generating the threshold signature using the estimated characteristics; and

forwarding to an object detection system the threshold signature.

18. The system of claim 17, further comprising retrieving from a pattern database a pattern signature that is associated with an object having similar characteristics as the estimated characteristics, wherein the retrieved pattern signature is the threshold signature.

19. The system of claim 18, wherein the estimated characteristics include one or more of height, weight, length, type of object, and hair length.

20. The system of claim 18,

wherein the pattern database includes a plurality of pattern signatures, each pattern signature associated with an object having object characteristics, and

wherein the threshold signature is generated based on a selection of the pattern signature having objects characteristics similar to the estimated characteristics.

21. The system of claim 17, wherein the reserved object in the photograph is an occupant'"'"'s pet.
