Coach driver fatigue evaluation method based on the lane departure frequency

Coach driver fatigue state evaluation method of the lane departure frequency based, belongs to technical field of automobile safety, including cameras, microcontroller, data lines, and a vehicle sound system, the camera captured the image information signal to the microcontroller; SCM obtained image data signal, and detects both side edges of the vehicle, the lane line position of the left edge and the right edge of the lane line; both side edges of the vehicle are calculated from the left lane and the right lane line edge line edge; and a recording cycle frequency lane departure occurs. Fatigue state of the driver is judged based on the detected data. The present invention has greatly improved over the prior art in the installation position and fatigue determination algorithm, it does not affect the driver's normal driving state of the driver monitor case, enabling real-time monitoring, and provide voice prompts, can effectively avoid fatigue caused by traffic accidents.
