To provide a visual recognition object detection device capable of appropriately detecting an object being visually recognized by a driver.SOLUTION: A visual recognition object detection device 1 includes: a camera 10 for imaging a driver; a face direction detection section 11 for detecting a face direction of a driver from an image captured by the camera 10; a visual line detection section 12 for detecting a visual line of a driver from an image captured by the camera 10; a visual recognition object estimation section 13 for estimating a visual recognition object being visually recognized by a driver from a visual line or a face direction; and an output section 14 for outputting information indicating a visual recognition object estimated by the visual recognition object estimation section 13. The visual recognition object estimation section 13 estimates a visual recognition object on the basis of a visual line detected by the visual line detection section 12 when detection accuracy of a visual line detected by the visual line detection section 12 is equal to or more than a predetermined threshold, and estimates a visual recognition object on the basis of a face direction detected by the face direction detection section 11 when detection accuracy of a visual line is less than the predetermined threshold.SELECTED DRAWING: Figure 1
【課題】運転者が視認している対象を適切に検知できる視認対象検知装置を提供する。【解決手段】視認対象検知装置1は、運転者を撮影するカメラ10と、カメラ10にて撮影した画像から運転者の顔向きを検知する顔向き検知部11と、カメラ10にて撮影した画像から運転者の視線を検知する視線検知部12と、視線または顔向きから運転者が視認している視認対象を推定する視認対象推定部13と、視認対象推定部13にて推定した視認対象を示す情報を出力する出力部14とを備える。視認対象推定部13は、視線検知部12にて検知した視線の検知精度が所定の閾値以上の場合には、視線検知部12にて検知した視線に基づいて視認対象の推定を行い、視線の検知精度が所定の閾値より小さい場合には、顔向き検知部11にて検知した顔向きに基づいて視認対象の推定を行う。【選択図】図1
