To provide a driver state estimating apparatus that improves accuracy in estimating the state of a driver during vehicle traveling.SOLUTION: A driver state estimating apparatus 20 comprises: a camera 100 as a visual line detection device that detects a visual line direction of a driver; a controller 50; an image processing unit 52 that performs image processing for an image taken by the camera and outputs image data; an eye-catching degree calculation unit 53 that calculates an eye-catching degree indicating easiness in attracting the visual line of the driver, for a target on a front side of a vehicle, on the basis of the image data, and generates an eye-catching degree map; and an estimation unit 54 that estimates the state of the driver on the basis of a visual line direction of the driver detected by the visual line detection device and the eye-catching degree map. The eye-catching degree calculation unit calculates an eye-catching degree, in consideration of vehicle components which come into the visual field of the driver when the vehicle travels.SELECTED DRAWING: Figure 3

    【課題】車両走行時における運転者の状態を推定する精度を向上させる運転者状態推定装置を提供する。【解決手段】運転者状態推定装置20は、運転者の視線方向を検知する視線検知装置としてのカメラ100、コントローラ50と、カメラにより撮影された画像に対して画像処理を行って、画像データを出力する画像処理部52と、画像データに基づいて、車両前側の物標に対して、運転者の視線の惹きつけやすさを示す誘目度を算出して、誘目度マップを生成する誘目度算出部53と、視線検知装置が検知した運転者の視線方向及び誘目度マップに基づいて、運転者の状態を推定する推定部54とを備える。誘目度算出部は、車両の走行時に運転者の視界領域に入る車両構成部材を考慮して誘目度を算出する。【選択図】図3
