Driving fatigue is one of the most important factors in traffic accident

in order to real-time and effectively detect driving fatigue

an algorithm fusing multiple fatigue characteristics is proposed for fatigue state judgement is designed

and build a vehicle FPGA-based embedded test platform.The multiple detection algorithm fuses

fatigue features of eyes and mouth

when a feature detection is affected

other features can be used for judgment of fatigue state.Compared with traditional single feature fatigue detection algorithm

it has higher detection efficiency.Experimental result show that the system algorithm is simple

reliability and real-time.
