VEHICLE VISION SYSTEM WITH DRIVER MONITORING
First Claim
1. A vision system of a vehicle, said vision system comprising:
- a pair of cameras disposed in a vehicle equipped with said vision system and each having a field of view encompassing a region where a head of a driver who is normally operating the equipped vehicle is located;
a control having an image processor operable to process image data captured by said cameras;
wherein said control, responsive to processing of captured image data by said image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction; and
wherein said control, responsive to processing by said image processor of image data captured by both cameras of said pair of cameras, is operable to determine a three dimensional eye position and a three dimensional gaze vector for at least one of the driver'"'"'s eyes.

Abstract
A vision system of a vehicle includes a pair of cameras and a control. The cameras are disposed in a vehicle and have a field of view encompassing a region where a head of a driver of the vehicle is located. The control includes an image processor operable to process image data captured by the cameras. The control, responsive to processing of captured image data by the image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction. The control, responsive to processing by the image processor of image data captured by both cameras of the pair of cameras, is operable to determine a three dimensional eye position and a three dimensional gaze vector for at least one of the driver'"'"'s eyes.

12. A vision system of a vehicle, said vision system comprising:
-
a pair of cameras disposed in a vehicle equipped with said vision system and each having a field of view encompassing a region where a head of a driver who is normally operating the equipped vehicle is located; wherein said cameras are spaced apart in the vehicle and forward of the head of the driver and wherein said cameras are disposed at generally opposite sides of the head of the driver, and wherein one of said cameras is disposed at a driver side A-pillar region of the equipped vehicle and another of said cameras is disposed at a center region of a dashboard of the equipped vehicle; a control having an image processor operable to process image data captured by said cameras; wherein said control, responsive to processing of captured image data by said image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction; wherein said control, responsive to processing by said image processor of image data captured by both cameras of said pair of cameras, is operable to determine a three dimensional eye position and a three dimensional gaze vector for at least one of the driver'"'"'s eyes; and wherein the three dimensional gaze vector is determined by fitting an ellipse to an iris of a respective eye of the driver, wherein said ellipse is generated responsive to processing of captured image data. - View Dependent Claims (13, 14, 15, 16)

17. A vision system of a vehicle, said vision system comprising:
-
a pair of cameras disposed in a vehicle equipped with said vision system and each having a field of view encompassing a region where a head of a driver who is normally operating the equipped vehicle is located; wherein said cameras are spaced apart in the vehicle and forward of the head of the driver and wherein said cameras are disposed at generally opposite sides of the head of the driver; an illumination source that emits illumination towards the region where the head of the driver who is normally operating the equipped vehicle is located; a control having an image processor operable to process image data captured by said cameras; wherein said control, responsive to processing of captured image data by said image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction; and wherein said control, responsive to processing by said image processor of image data captured by both cameras of said pair of cameras, is operable to determine a three dimensional eye position and a three dimensional gaze vector for each of the driver'"'"'s eyes. - View Dependent Claims (18, 19, 20)
