Patent ID: 8391554

Claim:
A method for detecting the location of at least one eye of a driver positioned in a driving seat of a vehicle using a single camera positioned inside the vehicle, said method comprising: determining a set of positional parameters corresponding to the driving seat, where said set of positional parameters includes an angle between a back-rest of the driving seat and a vertical plane, a distance between an edge of the driving seat and a center of the camera and a length of the back-rest of the driving seat; determining a set of parameters corresponding to the camera, wherein the set of parameters corresponding to the camera includes a focal length of the camera, an angle between the camera and a vertical plane and one or more positional parameters of the camera based on a known profile of an interior of the vehicle; capturing an image of a face of the driver using the camera; and detecting the eye location based on the set of positional parameters, the image of the face and the set of parameters corresponding to the camera.
