Dsp-based Fatigue Driving Real-time Monitoring System

Preventing fatigue driving becomes a key point to the traffic manage department for the case of fatigue driving have caused series traffic accidents.Point to those, we come up with the research of the fatigue driving alarm set, in order to make it apt in the protecting measure.Dynamic picture of eye obtained with video technology is a comparatively ideal non-contact measuring eyes tired degree methods, and utilize ADF and Hough transform technology of the real - time images to detect, track and analyze the state of eyes and pick - up characteristic parameter of eyes, count closing time of eyes in succession within regular hour, judge the tired degree and take the corresponding measure in value of calculating out PERCLOS.This paper take out the software and hardware design based on assemble language for fatigue driving alarm set. This set makes use of the single-computers technology and software design methods and also computer control technology. When designing, we programmed date collecting, date processing and filtering algorithm etc. We also made some PCB to realize the set's function. At last, compile the program in order to fit the hardware. Detection and track algorithm of eyes are transplanted the special - purpose DSP, develop the embedded real - time monitoring system of fatigue driving finally.Experiments show that the algorithm is simple, fast and the price is low. The set is fit of all the drivers, This set is value of the use of all the long-distance drivers.
