PROBLEM TO BE SOLVED: To provide a face orientation estimation device etc. capable of accurately counting the number of times that a driver has visually recognized an object even when the viewing behavior of the driver changes due to positional change of the vanishing point.SOLUTION: An on-vehicle device 40 functions as a face orientation estimation device for estimating the orientation of a face of a driver driving a vehicle. The on-vehicle device 40 acquires a detection result of the orientation of the face of the driver, and based on the acquired detection result, counts the number of times the driver has visually recognized the object such as a side mirror installed on the vehicle. The on-vehicle device 40 further determines whether the viewing behavior of the driver viewing the object has changed due to a positional change of a vanishing point in a foreground, and when determining that the viewing behavior has changed, changes the content of the counting processing according to the positional change of the vanishing point.SELECTED DRAWING: Figure 1
【課題】消失点の位置変化に起因して運転者の視認行動が変化しても、運転者が視認対象物を視認した回数を精度良く計数することが可能な顔向き推定装置等の提供。【解決手段】車載デバイス40は、車両を運転する運転者の顔向きを推定する顔向き推定装置として機能する。車載デバイス40は、運転者の顔向きを検出した検出結果を取得し、取得した検出結果に基づいて、車両に設置されたサイドミラー等の視認対象物を運転者が視認した回数を計数する。加えて車載デバイス40は、前景中での消失点の位置変化に起因して視認対象物を視認する運転者の視認行動が変化したか否かを判定し、視認行動が変化したと判定した場合には、消失点の位置変化に合わせて計数処理の内容を変更する。【選択図】図1
