Title
(EN) OCCUPANT STATE DETECTION DEVICE AND OCCUPANT STATE DETECTION METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE DÉTECTION D'ÉTAT D'OCCUPANT
(JA) 乗員状態検出装置および乗員状態検出方法
Abstract
(EN) This occupant state detection device is provided with: a photographed image acquisition unit (11) that acquires a photographed image capturing an occupant; a temperature image acquisition unit (12) that acquires a temperature image indicating the temperature of the surface of the body of the occupant measured in a noncontact manner; a motion detection unit (14) that detects the motion of the occupant on the basis of the photographed image; a temperature detection unit (15, 15a) that detects the temperature of a hand of the occupant on the basis of the temperature image; and a wakefulness estimation unit (16, 16a) that estimates the wakefulness of the occupant on the basis of the temperature of the hand of the occupant detected by the temperature detection unit (15).
(FR) Ce dispositif de détection d'état d'occupant est pourvu : d'une unité d'acquisition d'image photographiée (11) qui acquiert une image photographiée capturant un occupant ; d'une unité d'acquisition d'image de température (12) qui acquiert une image de température indiquant la température de la surface corporelle de l'occupant mesurée sans contact ; d’une unité de détection de mouvement (14) qui détecte le mouvement de l'occupant d’après l'image photographiée ; d’une unité de détection de température (15, 15a) qui détecte la température d'une main de l'occupant d’après l'image de température ; et d’une unité d'estimation de vigilance (16, 16a) qui estime l'état de vigilance de l'occupant d’après la température de la main de l'occupant détectée par l'unité de détection de température (15).
(JA) 乗員を撮像した撮像画像を取得する撮像画像取得部(11)と、非接触で測定された乗員の体の表面の温度をあらわす温度画像を取得する温度画像取得部(12)と、撮像画像に基づいて乗員の動きを検出する動き検出部(14)と、温度画像に基づいて乗員の手の温度を検出する温度検出部(15,15a)と、動き検出部(14)が検出した乗員の動きと、温度検出部(15)が検出した乗員の手の温度とに基づいて、乗員の覚醒度を推定する覚醒度推定部(16,16b)とを備えた。
