Abstract

A video tracking system integrates a pair of video cameras into the vehicle instrument cluster. The video tracking system includes an instrument cluster in a vehicle having at least one vehicle related instrument. A video camera is located in the instrument cluster and is oriented to capture images of a driver of the vehicle. The system includes a processor for processing the images acquired by the video camera and determining one or more characteristics of the driver.

Claims

1. An imaging system integrated in an instrument cluster of a vehicle, said system comprising:

an instrument cluster in a vehicle comprising at least one vehicle related instrument;

a first video camera located in the instrument cluster and oriented to capture images of a driver of the vehicle;

a second video camera located in the instrument cluster of the vehicle and oriented to capture images of the driver of the vehicle; and

a processor for processing the images acquired by the first and second video cameras and determining one or more characteristics of the driver.

2. The system as defined in claim 1, wherein the first and second video cameras are displaced from one another.

3. The system as defined in claim 2, wherein the first and second video cameras are displaced by a distance of at least 8 cm.

4. The system as defined in claim 1, wherein each of the first and second video cameras is projected at an inclination angle in the range of 15°

to 30°

relative to a horizontal axis of the vehicle.

5. The system as defined in claim 1, wherein the first and second video cameras are mounted on a circuit board within the instrument cluster.

6. The system as defined in claim 1 further comprising a circuit board, wherein the at least one instrument, the first and second video cameras, and processor are mounted to the printed circuit board.

7. The system as defined in claim 1, wherein each of the first and second video cameras comprises an integrated circuit imager.

8. The system as defined in claim 1, wherein said at least one instrument comprises any one of a speedometer, a fuel indicator, and a temperature indicator.

9. An image tracking system integrated in an instrument cluster of a vehicle, said system comprising:

an instrument cluster for mounting in a vehicle and comprising a circuit board and at least one vehicle related instrument connected to the circuit board;

a video camera located in the instrument cluster and connected to the circuit board, wherein the video camera is oriented to capture images of a driver of the vehicle; and

a processor for processing the images acquired by the video camera and tracking one or more characteristics of the driver.

10. The system as defined in claim 9, wherein the video camera comprises a first video camera and a second video camera, wherein the first and second video cameras are displaced from one another.

11. The system as defined in claim 10, wherein the first and second video cameras are displaced by a distance of at least 8 cm.

12. The system as defined in claim 9, wherein the video camera is projected at an inclination angle in the range of 15°

to 30°

relative to a horizontal axis of the vehicle.

13. The system as defined in claim 9, wherein the processor is connected to the circuit board.

14. The system as defined in claim 9, wherein the video camera comprises an integrated circuit imager.

15. An image tracking system integrated in an instrument cluster of a vehicle, said system comprising:

an instrument cluster for mounting in a vehicle and comprising at least one vehicle related instrument;

a first video camera located in the instrument panel and oriented to capture images of the driver of the vehicle;

a second video camera located in the instrument cluster and oriented to capture images of the driver of the vehicle, wherein the first and second video cameras are displaced from one another; and

a processor for processing the images acquired by the first and second video cameras and determining one or more characteristics of the driver.

16. The system as defined in claim 15, wherein the first and second video cameras are displaced by a distance of at least 8 cm.

17. The system as defined in claim 15, wherein the instrument cluster further comprises a circuit board, wherein the at least one instrument, the first and second video cameras, and processor are mounted to the printed circuit board.

18. The system as defined in claim 15, wherein the first and second video cameras each comprises an integrated circuit imager.

19. The system as defined in claim 15, wherein said at least one instrument comprises any one of a speedometer, a fuel indicator, and a temperature indicator.
