A method of driving fatigue detection based on eye location

For a driver fatigue monitoring system, one of the most important problems to solve is eye location. This paper presents a method of eye location based on AAM and a method of driver fatigue detection based on an improved method to calculate PERCOLS. AAM (Active Appearance Model) model is composited by the appearance model and fitting algorithm which is an efficient algorithm to extract facial feature points. First establish the AAM model, then use the fitting algorithm to detect the position of face and locate the position of eye, next calculate the improved physical PERCLOS which is used to measure the driver fatigue to determine the current state of driver is fatigue or not.
