To detect a reversely traveling vehicle without previously setting a detection area corresponding to an installation place.SOLUTION: A reverse traveling vehicle detection device comprises: an acquisition section for acquiring a captured image in a range including a road imaged by a camera; a first setting section for setting a plurality of cross lines to cross with the road with respect to the captured image; a storage section for storing positions of intersection points of a travel route of a vehicle traveling on the road in a predetermined direction with the cross lines; a second setting section for, when positions of a predetermined or more number of intersection points are stored, setting a detection area to detect a reverse traveling vehicle traveling in a direction different from the predetermined direction based on the stored predetermined or more number of intersection points; and a detection section for detecting the reverse traveling vehicle within the detection area.SELECTED DRAWING: Figure 3
【課題】設置場所に応じた検知領域の設定を事前に行わなくとも逆走する車両を検知する。【解決手段】本逆走車検知装置は、カメラが撮影した道路を含む範囲の撮像を取得する取得部と、前記撮像に対して、前記道路と交差する複数の交差線を設定する第1設定部と、前記道路を所定方向に走行する車両の走行経路と前記交差線との交点の位置を記憶する記憶部と、所定数以上の前記交点の位置が記憶されると、記憶された前記所定数以上の前記交点に基づいて、前記所定方向とは異なる方向に走行する逆走車を検知する検知領域を設定する第2設定部と、前記検知領域内における前記逆走車を検知する検知部と、を備える。【選択図】図3
