Driver Surveillance System utilizes face detection technique to track driver’s face and judge inattentive driving. By analyzing the position of driver’s face, once a frontal face disappeared in a reasonable area, the system regards it as inattentive driving and raises a warning signal to alert the driver immediately to prevent from accidents. Image processing techniques are implemented on embedded DSP platform. Wireless transmission techniques can also be integrated to improve the performance of commercial vehicle team management.
