Abstract

The unattended surveillance device may include a housing to be positioned for unattended surveillance, a video camera associated with or carried by the housing to capture video, and an image processor carried by the housing and cooperating with the video camera. The image processor extracts moving objects in the foreground of the captured video, generates a profile image or sequence of profile images of the extracted moving objects, compresses the sequence of profile images, and generates a surveillance information packet based upon the compressed sequence of profile images. Also, a wireless transmitter or transceiver may be associated with the image processor to transmit the surveillance information packet to a surveillance monitoring station.

Claims

1. A surveillance device comprising:

a housing;

a video camera associated with the housing to capture surveillance video;

an image processor carried by the housing and cooperating with the video camera

to extract moving objects in a foreground of the surveillance video,

to generate at least one profile image of the extracted moving objects,

to compress the at least one profile image, and

to generate a surveillance information packet based upon the compressed profile image; and

a wireless transmitter associated with the image processor to transmit the surveillance information packet to a surveillance monitoring station.

2. The unattended surveillance device of claim 1 wherein the image processor generates the at least one profile image as a sequence of bi-tonal profile images.

3. The unattended surveillance device of claim 2 wherein the image processor compresses the sequence of bi-tonal profile images according to a Joint Bi-level Image experts Group (JBIG) format.

4. The unattended surveillance device of claim 1 wherein the video camera comprises at least one of a visible and infrared (IR) spectrum video camera.

5. The unattended surveillance device of claim 1 wherein the image processor is also to generate object classification information based upon the at least one profile image, and to include the object classification information in the surveillance information packet.

6. The unattended surveillance device of claim 5 wherein the object classification information comprises information regarding the moving objects in the at least one profile image being at least one of a vehicle, a person and an animal.

7. The unattended surveillance device of claim 6 wherein the object classification information further comprises information regarding at least one of a type of vehicle, a type of animal, a quantity of moving objects, a cargo carried by the moving objects, a direction of movement and an action.

8. The unattended surveillance device of claim 1 further comprising a battery carried by the housing to power the video camera, image processor and wireless transmitter.

9. The unattended surveillance device of claim 1 further comprising a detector carried by the housing to selectively activate the video camera.

10. A surveillance information device comprising:

an image processor to

extract moving objects in a foreground of surveillance video,

generate a sequence of profile images of the extracted moving objects,

generate object classification information based upon the sequence of profile images,

compress the sequence of profile images, and

generate a surveillance information packet based upon the compressed sequence of profile images and the object classification information; and

a wireless transmitter cooperating with the image processor to transmit the surveillance information packet to a surveillance monitoring station.

11. The surveillance information device of claim 10 wherein the image processor generates the sequence of profile images as a sequence of bi-tonal profile images.

12. The surveillance information device of claim 10 wherein the sequence of image frames comprises at least one of visible and infrared (IR) spectrum video image frames.

13. The surveillance information device of claim 10 wherein the object classification information comprises information regarding the moving objects in the sequence of profile images being at least one of a vehicle, a person and an animal.

14. A method of surveillance comprising:

positioning a surveillance device for unattended surveillance, the device comprising a housing and associated video camera, an associated image processor and an associated wireless transmitter; and

operating the surveillance device to capture surveillance video, to extract moving objects in a foreground of the surveillance video, to generate at least one profile image of the extracted moving objects, to compress the profile image, to generate a surveillance information packet based upon the compressed profile image and to transmit the surveillance information packet to a surveillance monitoring station.

15. The method of claim 14 wherein the image processor generates the at least one profile image as a sequence of bi-tonal profile images.

16. The method of claim 15 wherein the image processor compresses the sequence of bi-tonal profile images according to a Joint Bi-level Image experts Group (JBIG) format.

17. The method of claim 14 wherein the video camera captures at least one of a visible and infrared (IR) spectrum video sequence of image frames.

18. The method of claim 14 wherein the image processor also generates object classification information based upon the at least one profile image, and includes the object classification information in the surveillance information packet.

19. The method of claim 18 wherein the object classification information comprises information regarding the moving objects in the sequence of profile images being at least one of a vehicle, a person and an animal.

20. The method of claim 14 wherein operating the surveillance device further comprises selectively activating the video camera via a detector.
