Abstract
본 발명은 소정 시간마다 운전자의 눈 영역을 포함하는 얼굴영역을 촬상하여, 상기 촬상된 얼굴 영역의 화상데이터에 의거하여 운전자의 눈 깜박거림 시간(τ)을 검출하여 눈 깜박거림 시간(τ)이 임계치(역치) 이상으로 되는 회수(Cs)를 구하며,제2소정시간에 있어서의 눈 깜박거리는 전체회수(Cb)에 대해 상기 눈 깜박거림 시간(τ)이 임계치 이상으로 되는 회수(Cs)의 비율(LBR)을 구해 각성도를 추정하는 각성도 추정장치에 있어서,운전개시부터 1소정시간의 사이에 검출되는 상기 눈 깜박거림 시간(τ)을 설정하도록 하였기 때문에 눈 깜박거림의 개인차에 영향을 받지 않고 운전자의 각성도를 추정할 수 있게된다.
