A railway track information acquisition device according to an embodiment includes an image acquisition unit, a track information acquisition unit, a conversion unit, and a comparison unit. The image acquisition unit acquires a captured image in the direction of travel of the railway vehicle. The route information acquisition unit acquires position information of a first route in the direction in which the railway vehicle travels, on the basis of the position of the railway vehicle. The conversion unit converts the captured image and the first line into a common coordinate system. The comparison unit acquires, in a common coordinate system, position information of a first line corresponding to a second line in the captured image.
本实施方式所涉及的铁道线路信息取得装置具备图像取得部、线路信息取得部、变换部以及对照部。图像取得部获得铁道车辆的行进方向的拍摄图像。线路信息取得部基于铁道车辆的位置来取得铁道车辆行进的方向的第1线路的位置信息。变换部将拍摄图像与第1线路变换为共同的坐标系。对照部在共同的坐标系中取得拍摄图像内的第2线路所对应的第1线路的位置信息。
