The invention belongs to the technical field of vehicle safety and relates to a lane departure frequency-based method for evaluating state of fatigue of a long-distance bus driver. A camera, a single-chip microcomputer, a data line and a vehicle audio system are provided. The method includes: transmitting image information acquired by the camera to the single-chip microcomputer through signals; allowing the single-chip microcomputer to analyze the acquired image information and detect the positions of two edges of a vehicle, the position of the edge of a left lane and the position of the edge of a right lane; calculating distances from the two edges of the vehicle to the edge of the left lane and the edge of the right lane; recording the frequency of lane departure occurring in a period; judging the state of fatigue of the driver according to detected data. Compared with the prior art, the method has the advantages that equipment installation positions and a fatigue judging algorithm are greatly modified, the state of the driver is monitored without affecting the driver's normal driving, monitoring is real-time, corresponding voice prompts are provided, and traffic accidents caused by fatigue can be effectively avoided.
