Abstract
A driver monitoring system 1 includes: an image capturing device 11 which captures a face image of the driver; and a control device 50 to which the face image captured by the image capturing device is transmitted. The control device includes: a facial orientation recognition unit which recognizes the facial orientation angle of the driver based on the face image captured by the image capturing device; a zero-point setting unit which sets a zero-point of a pitch angle, yaw angle, and roll angle of the face of the driver based on the facial orientation angle recognized by the facial orientation recognition unit, when zero-point setting conditions, including that the velocity of the vehicle is equal to or greater than a predetermined velocity, are satisfied; and a state diagnosis unit that diagnoses a state of the driver based on the current facial orientation angle with respect to the zero-point set by the zero-point setting unit.
