This system recognize the driver's gaze direction in real-time and decide the distraction driving behavior. There are two stages in this system: detection stage and decision stage.
The driver's face is captured by a camera with IR light in the beginning of detection stage. Haar-like feature classifier is used to find the eye and mouth in the face region. Contours extracted by Canny edge detection are used to locate the pupil by applying Hough transform. The corners of eye and mouth are extracted as the feature points to calculate the yaw angle of face and the gaze direction relative to face of driver. The information are used to find the final gaze direction according to the front of driver's seat.
In the decision stage, nine timers are set to count the time that the gaze direction is not in the specific angle. The timer is reset when the driver is looking to the angle which is in the range of timer represented. When a timer counts 5 seconds, it is mean that the driver is not look at this angle and an alert signal is issued. The alert signal may remind driver to look this angle which has not looked for 5 seconds. Therefore, the proposed system will warn the driver to keep attention on the driving safety.
