Fatigue driving monitoring method and fatigue driving monitoring device

Abstract

The invention discloses a fatigue driving monitoring method and a fatigue driving monitoring device. The method comprises the following steps: collecting driver head information through a camera; whenthe vehicle speed is greater than a preset speed, a first camera positions a side face head contour of a driver in real time and tracks and positions upper and lower lip characteristic points of a mouth in real time and monitors the opening of the mouth; and when the opening of the mouth is greater than a preset threshold value and the duration is longer than a preset threshold value, judging that the driver yawns; when the yawning frequency is greater than a preset threshold value, judging that the driver is slightly fatigued, and alarming and prompting the driver; then the driver is judgedto be slightly fatigued, a second camera monitors upper and lower eyelid characteristic points of the front face of the driver in real time, monitors the openings of the eyes, and when the openings ofthe eyes are smaller than a preset threshold value and the duration is longer than a preset threshold value, judging that the eyes are fatigued; and when the eyes are judged to be fatigued and the number of times of eye fatigue is greater than a preset threshold value, judging that the driver is severely fatigued and alarming and prompting the driver. By taking a normal driving state of the driver as a judgment criterion, the driving safety of the driver can be improved effectively.

Description

technical field [0001] The invention relates to automobile safety driving monitoring technology, in particular to a fatigue driving monitoring method and device. Background technique [0002] With the improvement of people's living standards, cars have entered thousands of households, the number of drivers has increased rapidly, and road safety problems have become particularly prominent, and fatigue driving is a major cause of traffic accidents. [0003] At present, fatigue driving monitoring mainly includes monitoring methods based on human physiological signals, monitoring methods based on vehicle driving information, and monitoring methods based on facial information. [0004] The monitoring method based on human physiological signals needs to collect the driver's heartbeat signal, brain wave signal, etc., and make a judgment on the driving fatigue state according to the collected human physiological signals. Because the monitoring method of human physiological signals ...
