This occupant state detection device is provided with: an image acquisition unit (11) configured so as to acquire a plurality of frames of captured images acquired by an imaging device disposed in a vehicle; a feature information detection unit (12) configured so as to detect a line of sight and a face orientation of an occupant of the vehicle from the plurality of captured images; a factor estimation unit (13) configured so as to estimate a factor that obstructs the detection of the line of sight of the occupant in the captured image of the plurality of frames, and to output, as factor information, information indicating the estimated factor; and a distraction state determination unit (14) configured so as to determine whether or not the occupant is in a distraction state that is not suitable for driving the vehicle on the basis of all or part of the detected line of sight and face orientation and the output factor information for each frame of captured image, the distraction state determination unit (14) being configured so as to determine whether or not the occupant is in a distraction state that is not suitable for driving the vehicle on the basis of the captured image of the current frame. And determining whether or not the occupant is in a distracted state on the basis of factor information output for the captured image of the current frame, a face orientation detected from the captured image of the current frame, and a determination result of the distracted state made for the captured image of the past frame prior to the current frame.
本发明的乘员状态检测装置包括:构成为获取由配置在车辆内的拍摄装置获取的多帧拍摄图像的图像获取部(11);构成为从所述多帧拍摄图像中检测所述车辆的乘员的视线和面部朝向的特征信息检测部(12);构成为对所述多帧的拍摄图像推测妨碍所述乘员的视线检测的因素,输出表示所推测的因素的信息作为因素信息的因素推测部(13);以及构成为对各帧拍摄图像基于检测的视线和面部朝向及输出的因素信息的全部或一部分,判定所述乘员是否处于不适合驾驶所述车辆的分心状态的分心状态判定部(14),所述分心状态判定部构成为针对当前帧的拍摄图像,基于针对所述当前祯的拍摄图像而输出的因素信息、从所述当前帧的拍摄图像中检测到的面部朝向、以及针对所述当前帧之前的过去帧的拍摄图像所作的处于分心状态的判定结果,判定所述乘员是否处于分心状态。
