APPARATUS FOR DRIVER ANALYSIS USING REARVIEW MIRROR
First Claim
1. A driver analysis system for a vehicle, comprising:
- a video camera producing a video signal mounted in or on a body of the vehicle, said video camera having a field of view that includes an internal rearview mirror or an external rearview mirror, and said video camera being positioned such that it sees a face of a driver of the vehicle or a part of the face reflected by the rearview mirror when the mirror is aligned to allow the driver to see behind the vehicle;
a processing unit receiving a video signal from said video camera, said processing unit comprising;
a video grabber/digitizer, which receives said video signal from said camera and produces a sequence of digitized images;
a central processing unit;
a memory; and
an output control line; and
a control program, that runs on said processing unit, comprising image recognition algorithms that are capable of detecting the face of the driver in said image sequence,wherein the control program receives the images from said grabber/digitizer and performs a search for the face of the driver reflected in the mirror.
