To provide a rail track information generation device for generating rail track information specifying a search range of obstacle detection without any manpower.SOLUTION: A rail track information generation device of an embodiment includes: an acquisition section for acquiring positioning information showing a position of a railway vehicle for each point of a rail track based on a positioning signal received by a positioning device installed in the railway vehicle from a satellite through traveling of the railway vehicle on a pair of right/left rails, and image information obtained by capturing images in front of the railway vehicle for each point of the rail track imaged by an imaging device installed on the railway vehicle; a first generation section for generating first position information showing a center position of the right/left rails for each point of the rail track based on the positioning information; a second generation section for generating second position information showing positions of the right/left rails for each point of the rail track based on the first position information; a third generation section for generating third position information showing a position in the image information from the second position information; and a construction section for registering the generated second position information in the rail track information regarding the rail track stored in a storage device.SELECTED DRAWING: Figure 7

    【課題】支障物検知の探索範囲を規定した線路情報を人手によらずより正確に生成すること。【解決手段】実施形態の線路情報生成装置は、一対の左右レールを鉄道車両が走行することにより、前記鉄道車両に設置された測位装置で受信した、人工衛星からの測位信号、に基づく路線の地点ごとの前記鉄道車両の位置を示す測位情報と、前記鉄道車両に設置された撮像装置で撮像された前記路線の地点ごとの前記鉄道車両の前方を撮像した画像情報と、を取得する取得部と、前記測位情報に基づいて、前記路線の地点ごとに、前記左右レールの中央位置を示す第1位置情報を生成する第1生成部と、前記第1位置情報に基づいて、前記路線の地点ごとに、前記左右レールの位置を示す第2位置情報を生成する第2生成部と、前記第2位置情報から、前記画像情報における位置を示す第3位置情報を生成する第3生成部と、生成された前記第2位置情報を、記憶装置に記憶された、線路に関する線路情報、に登録する構築部と、を備える。【選択図】図7
