To provide a safe driving determination device and a method for appropriately obtaining a face direction angle of a driver.SOLUTION: A driver of a vehicle 1 is imaged by an imaging device 4 so as to acquire an angle value indicating a face direction angle of the driver with a travel direction of the vehicle 1 as reference. Then, it is determined whether or not the driver does not look ahead carefully on the basis of the acquired angle value. A control device 10 includes: an angle value acquisition section 32 for acquiring at least one of angle values of a face yaw-direction angle of the driver with respect to the travel direction and a face pitch-direction angle; an off-set value acquisition section 33 for acquiring an off-set value of an angle value corresponding to an imaging direction of the imaging device 4 with respect to a face of the driver through the use of angle values acquired by the angle value acquisition section 32 over a predetermined time; and an angle value correction section 34 for correcting an angle value acquired by the angle value acquisition section 32 through the use of an off-set value acquired by the off-set value acquisition section 33.SELECTED DRAWING: Figure 1
【課題】運転者の顔向き角度を適切に求める安全運転判定装置及び方法を提供する。【解決手段】車両1の運転者を撮像装置4によって撮像して車両1の進行方向を基準にしたときの運転者の顔向き角度を示す角度値を取得し、取得した角度値に基づいて運転者が前方不注視であるか否かを判定する。制御装置10は、進行方向に対する運転者のヨー方向の顔向き角度と、ピッチ方向の顔向き角度との少なくとも一方の角度値を取得する角度値取得部32と、角度値取得部32が所定時間に亘って取得した角度値を用いて、運転者の顔に対する撮像装置4の撮像方向に対応した角度値のオフセット値を取得するオフセット値取得部33と、角度値取得部32が取得した角度値を、オフセット値取得部33が取得したオフセット値を用いて補正する角度値補正部34と、を備える。【選択図】図1
