Fatigue driving detecting method based on driving behaviors

The invention discloses a fatigue driving detecting method based on driving behaviors. The problem that in the prior art, a road curvature factor can affect accuracy of a fatigue driving detecting method based on the driving behaviors is solved. A road alignment classifier and corresponding fatigue mode classifiers are established, road videos of a vehicle and driving behavior information in the process of vehicle travelling are collected in real time, driving behavior characteristic parameters of a driver under different road curvatures (a straight road and a curve road) are respectively extracted, current road alignment is determined according to a result output by the road alignment classifier, the corresponding fatigue mode classifiers are called, and therefore the fatigue state of the driver can be identified. The method achieves accurate detection of fatigue driving in real time.
