Abstract

A video processing system may include a display, at least one geospatial database, and a video processor. The video processor may cooperate with the display and the at least one geospatial database and be configured to display a georeferenced video feed on the display and defining a viewable area, and to overlay selected geospatially-tagged metadata onto the viewable area and relating to a geolocation outside the viewable area.

Claims

1. A video processing system comprising:

a display;

at least one geospatial database; and

a video processor cooperating with said display and said at least one geospatial database and configured to

display a georeferenced video feed on said display from a video camera having a field of view, the video feed defining a viewable area on said display, and

overlay selected geospatially-tagged metadata onto the georeferenced video feed within the viewable area and providing

a distance to a geospatial location outside the field of view of the video camera measured between a current frame center of the georeferenced video feed and the geospatial location based upon the at least one geospatial database, and

a bearing angle to the geospatial location measured between true north and a line connecting the current frame center and the geospatial location based upon the at least one geospatial database.

2. The video processing system of claim 1 wherein the selected geospatially-tagged metadata comprises at least one of geospatially referenced feature annotations, geospatially referenced video source locations, and geospatially referenced points of interest.

3. The video processing system of claim 1 wherein said video processor comprises an overlay generator configured to overlay the selected geospatially-tagged metadata onto the viewable area.

4. The video processing system of claim 3 wherein said overlay generator generates at least one indicator for the selected geospatially-tagged metadata.

5. The video processing system of claim 4 wherein the at least one indicator comprises at least one of a range indicator and a bearing indicator.

6. The video processing system of claim 1 wherein said video processor comprises a request handler configured to accept a query of said at least one geospatial database to generate the selected geospatially-tagged metadata.

7. The video processing system of claim 6 wherein the query is based upon at least one filtering parameter.

8. The video processing system of claim 7 wherein the at least one filtering parameter comprises at least one of a subject category filtering parameter, and a distance filtering parameter.

9. The video processing system of claim 1 wherein said at least one geospatial database comprises:

a first geospatial database of fixed geospatially-tagged metadata; and

a second geospatial database of variable geospatially-tagged metadata.

10. The video processing system of claim 1 wherein the video feed comprises a live video feed.

11. A video processing system comprising:

a display;

at least one geospatial database; and

a video processor cooperating with said display and said at least one geospatial database and configured to display a georeferenced video feed on said display from a video camera having a field of view, the video feed defining a viewable area on said display and comprising

a request handler configured to accept a query of said at least one geospatial database to generate selected geospatially-tagged metadata, and

an overlay generator configured to overlay the selected geospatially-tagged metadata onto the georeferenced video feed within the viewable area and providing

a distance to a geospatial location outside the field of view of the video camera measured between a current frame center of the georeferenced video feed and the geospatial location based upon the at least one geospatial database, and

a bearing angle to the geospatial location measured between true north and a line connecting the current frame center and the geospatial location based upon the at least one geospatial database.

12. The video processing system of claim 11 wherein the selected geospatially-tagged metadata comprises at least one of geospatially referenced feature annotations, geospatially referenced video source locations, and geospatially referenced points of interest.

13. The video processing system of claim 11 wherein said marker handler generates at least one indicator for the selected geospatially-tagged metadata.

14. The video processing system of claim 13 wherein the at least one indicator comprises at least one of a range and bearing.

15. A video processor for use with a display and at least one geospatial database, the video processor comprising:

a marker handler configured to determine selected geospatially-tagged metadata; and

an overlay generator configured to display a georeferenced video feed on the display from a video camera having a field of view, the video feed defining a viewable area on the display, and overlay the selected geospatially-tagged metadata onto the georeferenced video feed within the viewable area and providing

a distance to a geospatial location outside the field of view of the video camera measured between a current frame center of the georeferenced video feed and the geospatial location based upon the at least one geospatial database, and

a bearing angle to the geospatial location measured between true north and a line connecting the current frame center and the geospatial location based upon the at least one geospatial database.

16. The video processor of claim 15 wherein the selected geospatially-tagged metadata comprises at least one of geospatially referenced feature annotations, geospatially referenced video source locations, and geospatially referenced points of interest.

17. The video processor of claim 15 wherein said video processor comprises an overlay generator configured to overlay the selected geospatially-tagged metadata onto the viewable area.

18. A video processing method comprising:

displaying a georeferenced video feed on a display from a video camera having a field of view, the video feed defining a viewable area on the display; and

overlaying selected geospatially-tagged metadata onto the georeferenced video feed within the viewable area and providing

a distance to a geospatial location outside the field of view of the video camera measured between a current frame center of the georeferenced video feed and the geospatial location based upon the at least one geospatial database, and

a bearing angle to the geospatial location measured between true north and a line connecting the current frame center and the geospatial location based upon the at least one geospatial database.

19. The method of claim 18 wherein the selected geospatially-tagged metadata comprises at least one of geospatially referenced feature annotations, geospatially referenced video source locations, and geospatially referenced points of interest.

20. The method of claim 18 further comprising generating at least one indicator for the selected geospatially-tagged metadata comprising at least one of a range indicator and a bearing indicator.
