Abstract: A drowsiness determination system includes a first acquirer, a second acquirer, a third acquirer, and a determiner. The first acquirer acquires vibration information indicating the vibration of a vehicle. The second acquirer acquires head information indicating a variation in the movement of the head of an occupant. The third acquirer acquires sitting height information indicating the sitting height of the occupant. The determiner determines whether the occupant is drowsy based on the head information and the sitting height information, when the vibration information indicates the occurrence of the vibration of the vehicle.

Abstract: An estimation apparatus includes: an image information obtainer that obtains image information of a captured image of a driver; a first detector that detects face information indicating facial behavior of the driver, based on the image information; a first reliability calculator that calculates first reliability; a second detector that detects body information indicating body movement of the driver, based on the image information; a second reliability calculator that calculates second reliability; a weight setter that, when the face information and the body information are detected, sets a first weight corresponding to the face information and a second weight corresponding to the body information based on the first reliability and the second reliability; and an estimator that estimates drowsiness of the driver based on the face information weighted by the first weight and the body information weighted by the second weight.
