Abstract

A system for monitoring a driver of a vehicle is provided. The system includes an infrared flash to beam an infrared light at the driver; an infrared camera to capture the reflection from the beam; and a reflective infrared film adhered to a windshield of the vehicle. A method for implementing a driver monitoring system is provided. The method includes installation of an infrared reflective layer on a vehicle; installing an infrared camera and an infrared flash in a dashboard of the vehicle; and orientating either the infrared camera or the infrared flash in a direction facing the infrared reflective layer.

Claims

1. A system for monitoring a driver of a vehicle, comprising:

an infrared flash to beam an infrared light at the driver;

an infrared camera to capture an image illuminated by the beam, including reflections; and

a reflective infrared film incorporated into a windshield of the vehicle,

wherein the infrared flash is attached to a dashboard and in between a steering wheel and the dashboard and aimed upwardly toward the windshield, and the infrared flash is configured to beam the infrared light at the driver by first reflecting the light off the reflective infrared film, and the infrared camera is also located between the steering wheel and the dashboard, and is configured to detect the reflections of the driver after being reflected off the reflective infrared film.

2. The system according to claim 1, wherein the infrared camera is employed with a driver alertness detection system.

3. The system according to claim 1, wherein the infrared camera is employed with an interface device.

4. The system according to claim 1, wherein the infrared camera lens is aimed upwardly toward the windshield.

5. The system according to claim 1, wherein the infrared camera is configured to detect the infrared light reflected from the driver at a wavelength of 700 nm to 1000 nm.

6. The system according to claim 1, wherein upward is defined as perpendicular to a surface of the dashboard in between the steering wheel and windshield.

7. The system according to claim 1, wherein the infrared camera and the infrared flash are adjacent to each other.

8. The system according to claim 1, wherein the infrared camera is oriented to capture a hand gesture.

9. The system according to claim 1, wherein reflective infrared film is a see-through film that allows visible light to pass through, but reflects infrared light.

10. An infrared camera device, the device comprising:

an attachment unit to attach to a dashboard of a vehicle, and in between the dashboard and a steering wheel of the vehicle;

an infrared camera lens to capture a reflection of a driver of the vehicle,

the vehicle includes an infrared flash, and in response to the infrared flash generating an infrared light, the reflection of the driver is generated,

the infrared flash is attached to the dashboard and in between the dashboard and a steering wheel and aimed upwardly toward the windshield, and

the infrared flash is configured to project the infrared light first off the windshield before being propagated to the driver.

11. The device according to claim 10, wherein an infrared reflective layer is included in the fabrication of the windshield.

12. The device according to claim 10, wherein the attachment unit'"'"'s angle relative to the dashboard is adjustable.

13. The device according to claim 10, wherein the infrared camera lens is aimed upwardly toward the windshield.

14. The device according to claim 10, wherein the infrared camera lens is aimed at an acute angle relative to horizontal toward the driver.

15. A system for monitoring a driver of a vehicle, comprising:

an infrared flash to beam an infrared light at the driver;

an infrared camera to capture an image illuminated by the beam, including reflections; and

a reflective infrared film incorporated into a windshield of the vehicle,

wherein the infrared flash is attached to a dashboard and in between a steering wheel and the dashboard and aimed at an acute angle relative to horizontal toward the driver, and the infrared flash is configured to beam the infrared light at the driver directly,

and the infrared camera is also located between the steering wheel and the dashboard and aimed upwardly toward the windshield, and is configured to detect the reflections of the driver after being reflected off the reflective infrared film.
