Background
Fatigue driving is one of the key factors of road traffic accidents. In recent years, with the development of technology, a driver fatigue state monitoring system (DMS) has been popularized.
The fatigue monitoring system can be divided into direct monitoring and indirect monitoring according to the monitoring signal attribute. The indirect monitoring is combined with the vehicle state to analyze the driving behavior signal of the driver, so that the cost is lower, but the precision is not as high as that of direct monitoring; the direct monitoring uses the physiological signals of the driver such as facial movement, eye movement, electrocardio, electroencephalogram and the like, and has higher precision. Compared with the acquisition of electrocardio signals and brain signals, the acquisition of facial and eye movement signals is quicker and more accurate. Therefore, the fatigue monitoring system adopting the camera to directly monitor the facial and eye movement signals of the driver is the most extensive in the market at present.
The arrangement positions of the fatigue monitoring cameras can be basically divided into three categories: 1. on the left side of the driver, such as where the A-pillar and instrument panel overlap; 2. on the right side of the driver, e.g. on the inside rear view mirror housing or base; 3. in front of the driver, e.g. on the combination switch shield. The yaw angles of the first two types of positions are large, the performance is general, and the camera protrudes out of the surface of the interior trim, so that the integral feeling of the vehicle interior trim is influenced. The yaw angle in front of the driver is zero, and the performance is good.
The casing of fatigue monitoring camera is opaque material, when being located combination meter the place ahead, can lead to the fact the formation combination meter blind area that shelters from to the display area of combination meter, and the effective display area of combination meter diminishes, influences space utilization.
