Abstract:
Provided is at least two of a direction determination unit which determines that the state is abnormal when a gaze direction of a driver of a vehicle is not within a first predetermined range based on a captured image of a head of the driver, a height determination unit which determines that the state is abnormal when a height of an eye of the driver is not within a second predetermined range based on the captured image, and a position determination unit which determines that the state is abnormal when a position of the head in a lateral direction is not within a third predetermined range based on the captured image; and an abnormal state determination unit which determines whether the state of the driver is abnormal based on the determination results of the determination units.

Claim (Index 1):
A driver abnormality detection device comprising:\n at least two of determination units including a direction determination unit which determines that a state is abnormal when a gaze direction of a driver of a vehicle is not within a first predetermined range based on a captured image of a head of the driver, a height determination unit which determines that the state is abnormal when a height of an eye of the driver is not within a second predetermined range based on the captured image, and a position determination unit which determines that the state is abnormal when a position of the head in a lateral direction is not within a third predetermined range based on the captured image; an abnormal state determination unit which determines that the state of the driver is abnormal when at least one of the determination units determines that the state has been abnormal continuously for a time equal to or longer than a continuation allowable time set for that determination unit; an information acquiring unit which acquires a surrounding situation of the vehicle; and a time correction unit which corrects the continuation allowable time set for at least one of the determination units according to the surrounding situation acquired by the information acquiring unit.
