Abstract

An imaging system includes a frame with a retroreflective bezel and cameras attached directly to the frame.

Claims

1. An object locating system comprising:

a frame defining an aperture with a perimeter, said frame having a retroreflective bezel about at least most of said perimeter; and

plural cameras attached directly to said frame.

2. An object locating system as recited in claim 1 further comprising camera-emitter assemblies, each of said camera-emitter assemblies including at least one of said cameras.

3. An object locating system as recited in claim 2 wherein said frame has corners and said camera-emitter assemblies are located in at least two of said corners.

4. object locating system as recited in claim 2 further comprising a display having a display screen, said frame being attached to said display so that said aperture is substantially coextensive with said display screen.

5. An object locating system as recited in claim 4 wherein said camera-emitter assemblies are rigidly connected to said display through said frame and are not directly attached to said display.

6. An object locating system as recited in claim 5 wherein said camera-emitter-assemblies sit flush with said display screen.

7. An object locating system as recited in claim 3 wherein said camera-emitter-assemblies are attached to said frame with screws.

8. An object locating system as recited in claim 7 wherein said cameras have unthreaded holes and said frame has threaded holes, said screws passing through said unthreaded holes and into said threaded holes.

9. An object locating system as recited in claim 7 wherein said camera-emitter assemblies have threaded holes and said frame has unthreaded holes, said screws passing through said unthreaded holes and into said threaded holes.

10. An object locating system as recited in claim 7 wherein said camera-emitter assemblies are attached to said frame with glue that contacts said cameras and said frame.

11. A method comprising:

forming a frame defining an aperture with a perimeter and a bezel about at least most of said perimeter; and

attaching camera-emitter assemblies to said frame and applying retroreflective material to said bezel.

12. A method as recited in claim 11 further comprising, after said assemblies are attached to said frame, attaching said frame to a display having a display screen so that said aperture is alighted with said display screen.

13. Method as recited in claim 12 further comprising, after attaching said frame to said display, presenting an image on said display.

14. A method as recited in claim 13 further comprising controlling said image by selectively blocking light emitted by said camera-emitter assemblies toward said bezel from being detected by said camera-emitter assemblies.

15. A method as recited in claim 14 wherein said light is infrared light.
