Abstract

A method and apparatus for determining a location of an object depicted in an image are disclosed. The location of an object depicted in an image is determined based on one or more of a camera location at a time the image was captured, object distance data, and camera orientation. Object distance data can include distance to subject data or focal length data. Camera orientation information can include azimuth and elevation angle which can be used to determine a direction from camera an object is located and an elevation of an object with respect to the camera. In one embodiment, image and object data are stored in a database which can be accessed by users to search for images and objects.

Claims

1. A method for determining a location of an object depicted in an image comprising:

receiving camera location data, distance to subject data, camera direction data and camera elevation angle data associated with an image; and

determining the location of an object depicted in the image based on the camera location data, distance to subject data, camera direction data, and camera elevation angle data.

2. A method for determining a location of an object depicted in an image comprising:

receiving camera location data and object distance data associated with an image; and

determining the location of an object depicted in the image based on the camera location data and the object distance data.

3. The method of claim 2 wherein the object distance data comprises distance to subject data.

4. The method of claim 2 wherein the object distance data comprises focal length data.

5. The method of claim 3 further comprising:

receiving camera orientation data,

wherein the determining is further based on the camera orientation data.

6. The method of claim 5 wherein the camera orientation data comprises a direction the camera is pointing when the image was acquired.

7. The method of claim 6 wherein the camera orientation data comprises an elevation angle of the camera when the image was acquired.

8. The method of claim 7 wherein the determining the location further comprises:

determining a direction from a camera location that the object is located based on the camera orientation data.

9. The method of claim 4 further comprising:

receiving camera orientation data,

wherein the determining is further based on the camera orientation data.

10. The method of claim 9 wherein the camera orientation data comprises a direction the camera is pointing when the image was acquired.

11. The method of claim 10 wherein the camera orientation data comprises an elevation angle of the camera when the image was acquired.

12. The method of claim 11 wherein the determining the location further comprises:

determining a direction from a camera location that the object is located based on the camera orientation data.

13. An apparatus for determining a location of an object depicted in an image, the apparatus comprising:

means for receiving camera location data and object distance data associated with an image; and

means for determining the location of an object depicted in the image based on the camera location data and the object distance data.

14. The apparatus of claim 13 wherein the object distance data comprises distance to subject data.

15. The apparatus of claim 13 wherein the object distance data comprises focal length data.

16. The apparatus of claim 14 further comprising:

means for receiving camera orientation data,

wherein the determining is further based on the camera orientation data.

17. The apparatus of claim 16 wherein the camera orientation data comprises a direction the camera is pointing when the image was acquired.

18. The apparatus of claim 17 wherein the camera orientation data comprises an elevation angle of the camera when the image was acquired.

19. The apparatus of claim 18 wherein the means for determining the location further comprises:

means for determining a direction from a camera location that the object is located based on the camera orientation data.

20. The apparatus of claim 15 further comprising:

means for receiving camera orientation data,

wherein the determining is further based on the camera orientation data.
