Abstract

Disclosed herein are system, method, and computer program product embodiments for camera surveillance planning and tracking using, for example, infrared technologies. An embodiment operates by distilling a moving foreground image from a frame, calculating a two-dimensional trajectory for the moving foreground object, determining a three-dimensional position for the moving foreground object, displaying the three-dimensional position on a map of an area.

Claims

1. A method, comprising:

distilling a moving foreground image from a frame, wherein the frame is received from a camera;

calculating a two-dimensional trajectory for the moving foreground image based upon a feature of the moving foreground object;

determining a three-dimensional position for the moving foreground object, wherein determining a three-dimensional position is based upon the camera; and

displaying the three-dimensional position for the moving foreground object on a map of an area.

2. The method of claim 1, wherein the moving foreground image comprises a plurality of features.

3. The method of claim 2, the calculating further comprising:

assigning a vector to each of the plurality of features.

4. The method of claim 3, wherein the two-dimensional trajectory comprises a mean of the vectors.

5. The method of claim 1, wherein the camera comprises one of a pair of stereo cameras.

6. The method of claim 5, the determining a three-dimensional position, wherein determining the three-dimensional position is further based upon a relationship between the pair of stereo cameras.

7. The method of claim 1, wherein the map of an area comprises a plurality of blocks, wherein each block comprises a section of the area.

8. The method of claim 7, the displaying further comprising:

highlighting at least one of the plurality of blocks according to the three-dimensional position.

9. A system, comprising:

a memory; and

at least one processor coupled to the memory and configured to;

distill a moving foreground image from a frame, wherein the frame is received from a camera;

calculate a two-dimensional trajectory for the moving foreground image based upon a feature of the moving foreground object;

determine a three-dimensional position for the moving foreground object, wherein determining a three-dimensional position is based upon the camera; and

display the three-dimensional position for the moving foreground object on a map of an area.

10. The system of claim 9, wherein the moving foreground image comprises a plurality of features.

11. The system of claim 10, the at least one processor configured to calculate, further configured to:

assign a vector to each of the plurality of features.

12. The system of claim 9, wherein the camera comprises one of a pair of stereo cameras.

13. The system of claim 12, the at least one processor configured to determine, wherein determining the three-dimensional position is further based upon a relationship between the pair of stereo cameras.

14. The system of claim 9, wherein the map of an area comprises a plurality of blocks, wherein each block comprises a section of the area.

15. A tangible, non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

distilling a moving foreground image from a frame, wherein the frame is received from a camera;

calculating a two-dimensional trajectory for the moving foreground image based upon a feature of the moving foreground object;

determining a three-dimensional position for the moving foreground object, wherein determining a three-dimensional position is based upon the camera; and

displaying the three-dimensional position for the moving foreground object on a map of an area.

16. The non-transitory computer-readable device of claim 15, wherein the moving foreground image comprises a plurality of features.

17. The non-transitory computer-readable device of claim 16, the calculating operation further comprising:

assigning a vector to each of the plurality of features.

18. The non-transitory computer-readable device of claim 17, wherein the two-dimensional trajectory comprises a mean of the vectors.

19. The non-transitory computer-readable device of claim 18, wherein the camera comprises one of a pair of stereo cameras.

20. The non-transitory computer-readable device of claim 19, the determining operation, wherein determining the three-dimensional position is further based upon a relationship between the pair of stereo cameras.
