Abstract:
(EN) A detection device (101) acquires image information obtained by capturing images of a subject within a moving body (M). Further, the detection device (101) acquires illumination intensity information indicating the illumination intensity within the moving body (M). The detection device (101) generates first feature information relating to a time series of the pupil diameter of an eye of the subject within the moving body (M), on the basis of the acquired image information. The detection device (101) also generates second feature information relating to a time series of the illumination intensity within the moving body (M), on the basis of the acquired illumination intensity information. On the basis of the generated first feature information and second feature information, the detection device (101) generates response information relating to the reflex rate at which the pupil of the eye of the subject within the moving body (M) responds to the light illuminated onto the subject. The detection device (101) then detects the fatigue status of the subject on the basis of the generated response information.
(FR) Selon l'invention, un dispositif de détection (101) acquiert des informations d'image obtenues par capture d'images d'un sujet à l'intérieur d'un corps mobile (M). En outre, le dispositif de détection (101) acquiert des informations d'intensité d'éclairage indiquant l'intensité d'éclairage à l'intérieur du corps mobile (M). Le dispositif de détection (101) génère des premières informations de caractéristiques relatives à une série chronologique du diamètre de pupille d'un œil du sujet à l'intérieur du corps mobile (M), sur la base des informations d'image acquises. Le dispositif de détection (101) génère également des secondes informations de caractéristiques relatives à une série chronologique de l'intensité d'éclairage à l'intérieur du corps mobile (M), sur la base des informations d'intensité d'éclairage acquises. Sur la base des premières informations de caractéristiques et des secondes informations de caractéristiques générées, le dispositif de détection (101) génère des informations de réponse concernant le rythme réflexe auquel la pupille de l'œil du sujet à l'intérieur du corps mobile (M) répond à la lumière envoyée sur le sujet. Le dispositif de détection (101) détecte ensuite l'état de fatigue du sujet sur la base des informations de réponse générées.
(JA) 検知装置(101)は、移動体(M)内の被写体を撮像した画像情報を取得する。また、検知装置(101)は、移動体(M)内の照度を示す照度情報を取得する。検知装置(101)は、取得した画像情報に基づいて、移動体(M)内の被写体の瞳孔径の時系列変化に関する第1の特徴情報を生成する。検知装置(101)は、取得した照度情報に基づいて、移動体(M)内の照度の時系列変化に関する第2の特徴情報を生成する。検知装置(101)は、生成した第1の特徴情報と第2の特徴情報とに基づいて、移動体(M)内の被写体に照射された光に対する被写体の瞳孔の反射速度に関する反応情報を生成する。検知装置(101)は、生成した反応情報に基づいて、被写体の疲労状態を検知する。
