Technical Field

Background
Traffic safety involves many factors such as people, vehicles, roads and environment, and according to statistics, 25-30% of all the automobile collision accidents in the world are related to fatigue driving every year. The driving fatigue detection technology can be researched to effectively reduce and prevent the occurrence of driving accidents. At present, the detection research method aiming at the driving fatigue at home and abroad mainly adopts two methods of subjective detection and objective detection. The subjective detection method is mainly used for self-feeding back the fatigue state of a driver in the driving process, and the method is convenient to implement as a research means, but cannot reflect the fatigue state of the driver in real time. The objective detection method mainly reflects the driving fatigue by measuring relevant objective parameters such as vehicles, drivers and the like in the driving process. The objective test is mainly performed from 3 aspects: 1) detecting based on the expression characteristics of the driver; 2) detection based on vehicle parameters; 3) the method is based on the detection of the physiological signal characteristics of the driver, wherein the detection of the expression characteristics of the driver judges the fatigue state of the driver by detecting the individual characteristics of the driver, such as pupil diameter, eyelid activity, eye closing state, facial expression, head movement and the like. The non-contact measurement has no influence on the driving of the driver and is simple and easy to implement, but the fatigue judgment standard is easily influenced by conditions such as personal behaviors, collection angles and environments, so that the detection system cannot always accurately predict the fatigue state of the driver, and the use requirement cannot be met.
