Abstract:
A railway line information acquisition device according to the present embodiment comprises an image acquisition unit, a line information acquisition unit, a conversion unit, and a contrast unit. The image acquisition unit acquires a captured image of a railway vehicle in a traveling direction. The line information acquisition unit acquires, on the basis of the location of a railway vehicle, location information about a first railway in the railway vehicle traveling direction.
