Investigatingthestructureandperformanceofdriverʹsfacemonitoring system in recognizing the fatigue and decon deconcenteration

Annually, a lot of driving accidents occur due to the fatigue and deconcenteration of the drivers and breeds a lot of financial and life damage. Using the system of appearance superrision is one of the approaches to discern the fatigue and deconcenteration of the drivers. Research showed that there is a considerable relation between the fatigue rate and the activities of the eye. The main signs of fatigue are the reduction of distance between two eye lids, the increase of eye lid period and finally the increase in eye lide numbers besides, the fatigue problem and sleepiness and also deconcentration of the drivers are accident causing. For an instance, turning your head to your around and eye liding for a long time are main causes of the driverʹs deconcenteration. The system of appearance supervision discovers the fatigue and deconcenteration of the drivers by recieving pictures of the drivers with camera and processing them. Then the fatigue rate and deconcentration of the driver is evaluated by the analysis and discovery of the stable features and in case of necessity you will receive notice. In this paper, by reviewing the system of appearance super vision, we studied the structure and performance and we will also consider the merits and demerits of this system. Key Words: driverʹs appearance monitoring, fatigue recognition, sleepiness recognition, deconcentration recognition, accident prevention
