To provide a monitoring device that can accurately determine a gaze position of a driver.SOLUTION: A monitoring device includes: a first estimation unit that estimates a face direction and a visual line direction of a driver based on an image representing the vicinity of a driver seat; a second estimation unit that estimates a gazing area within a vehicle cabin where the driver's face is facing based on the face direction of the driver estimated by the first estimation unit; a determination unit that determines a gaze position of the driver using a predetermined determining criterion based on the visual line direction estimated by the first estimation unit; and a changing unit that changes the determining criterion so that the determination unit is more likely to determine that the gaze position is included in the gazing area more than in an adjacent region adjacent to the gazing area. The determination unit determines the gaze position of the driver using the determining criterion changed by the changing unit.SELECTED DRAWING: Figure 2
【課題】ドライバの注視位置を正確に判定できる監視装置を提供する。【解決手段】監視装置は、運転席の近傍を表す画像に基づいて、ドライバの顔の向き及び視線方向を推定する第1推定部と、第1推定部によって推定されたドライバの顔の向きに基づいて、ドライバの顔が向いている車室内の注視領域を推定する第2推定部と、第1推定部によって推定された視線方向に基づいて、ドライバの注視位置を所定の判定基準を用いて判定する判定部と、判定部によって、注視領域と隣接する隣接領域よりも注視領域に注視位置が含まれていると判定されやすくなるように、判定基準を変更する変更部と、を有し、判定部は、変更部によって変更された判定基準を用いて、ドライバの注視位置を判定する、ことを特徴とする監視装置。【選択図】図2
