To provide technology for supporting vehicle type discrimination of a toll collector.SOLUTION: A vehicle confirmation support device according to an embodiment comprises: a photographic image storage unit which stores a photographic image photographed by a camera loaded with a wide angle lens; a vehicle detection unit which detects a vehicle from the photographic image; an axle detection unit which detects an axle of the detected vehicle; an axle bottom edge determination unit which determines an axle bottom edge of the detected axle; a Tilt parameter storage unit which stores a Tilt parameter of the camera loaded with the wide angle lens; a Tilt parameter correction determination unit which determines whether the Tilt parameter is required to be corrected on the basis of whether the axle bottom edge is included in a noticing correction area to be an object of correction of distortion in the photographic image; and a Tilt parameter correction unit which corrects the Tilt parameter so that the axle bottom edge is included in the noticing correction area when it is determined that the Tilt parameter is required to be corrected.SELECTED DRAWING: Figure 12

    【課題】収受員の車種判別を支援する技術を提供すること。【解決手段】実施形態に係る車両確認支援装置であって、広角レンズ搭載カメラによって撮影された撮影画像を記憶する撮影画像記憶部と、撮影画像から車両を検知する車両検知部と、検知された車両の車軸を検出する車軸検出部と、検出された車軸の車軸下端を決定する車軸下端決定部と、広角レンズ搭載カメラのTiltパラメータを記憶するTiltパラメータ記憶部と、撮影画像の中の歪みの補正の対象となる注目補正領域内に車軸下端が含まれているかどうかに基づいて、Tiltパラメータを修正する必要があるかどうかを判定するTiltパラメータ修正判定部と、Tiltパラメータを修正する必要があると判定した場合、注目補正領域内に車軸下端が含まれるようにTiltパラメータを修正するTiltパラメータ修正部と、を備える。【選択図】 図12
