Driver Alertness Monitoring Using Fusion of Facial Features and Bio-Signals
Driver Alertness Monitoring Using Fusion of Facial Features and Bio-Signals
This article begins with an extensive review of the literature on incorporating sensors into transport systems to monitor driver alertness. The fatigue monitoring system developed by the authors, which incorporates elements of prior work is implemented in an Android-based smartphone. A webcam is placed on the dashboard in front of the driver to capture the image of the driver’s face and a finger oximeter sensor is installed on the steering wheel to collect information about blood flow in the finger. The smartphone receives the signals via connected wireless sensor. A Dynamic Bayesian network (DBN) paradigm is programmed in the smartphone to perform statistical analysis on driver fatigue level based on extracted information from the two sensor sources mentioned above.
