Abstract

A system for mounting a camera 46 within a vehicle is illustrated. The camera 46 may be positioned behind an IR transmissible window 82 within the vehicle and within a housing 36 within the vehicle. The camera 46 is thus placed between the windshield 20 and the housing 36 so that the field of view 60 of the camera is through the window 82. A notch shape 78 or hole 26 may be formed within the windshield so that the IR transmissive portion may be inserted therein.

Claims

1. A system comprising:

a windshield with a top side, a bottom side, a right side and a left side, said top side have a notch shape formed therein; and

an insert having an IR transmissive portion is coupled to said top side within said notch so that the topside with the insert forms a continuous side.

2. A system as recited in claim 1 further comprising a grommet disposed between the windshield and the window.

3. A system as recited in claim 1 further comprising a housing rigidly coupled to a vehicle roof structure.

4. A system as recited in claim 1 further comprising a seal disposed between the housing and the windshield.

5. A system as recited in claim 1 further comprising a camera disposed within the housing.

6. A system as recited in claim 1 wherein the camera is coupled to the insert.

7. A system as recited in claim 1 wherein the camera is coupled to the housing.

8. A system as recited in claim 1 wherein the insert is composed of a near IR transmissive material separate from a far IR transmissive portion.

9. A system comprising:

a windshield having a hole therein;

an IR transmissive window disposed within the hole; and

a grommet disposed between the windshield and the window.

10. A system as recited in claim 9 further comprising a housing coupled between the roof and the windshield, the housing coupled to a camera positioned therein, said camera receiving IR through the IR transmissive window.

11. A system as recited in claim 9 wherein the IR transmissive window comprises a near infrared transmissive portion and a far infrared transmissive portion.

12. A system as recited in claim 11 further comprising a first camera receiving near infrared light and second camera is coupled receiving far infrared light.

13. A system as recited in claim 9 further comprising a seal disposed between the housing and the windshield.

14. A method comprising:

coupling an insert having a near IR transmissive portion and a far IR transmissive portion into a notch or hole within a windshield;

receiving a near infrared light in a first camera through the near infrared portion; and

receiving far infrared light in a second camera through the far infrared portion.

15. A method as recited in claim 14 further comprising mounting the near infrared camera to the roof and rigidly coupling a housing around the camera to the roof.

16. A method as recited in claim 14 further comprising coupling the camera to the IR transmissive portion.

17. A method as recited in claim 14 wherein the insert of germanium IR transmissive material is composed.

18. A method as recited in claim 14 wherein the near IR transmissive portion is in a windshield wiper path.

19. A method as recited in claim 14 wherein coupling the insert comprises providing a flange on the insert and coupling the flange to the windshield.

20. A method as recited in claim 14 further comprising coupling the insert to the window insert with a retainer coupled to the IR transmissive portion and the insert.
