Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2019/150924
Kind Code:
In methods for detecting a track from an edge and a luminance gradient, detection parameters change in accordance with a change in the external environment, and thus it is difficult to derive parameters which can be applied in all external environments, resulting in the problem of being unable to ascertain the shape of the track from the external environment. This track transportation system, which travels on a track, is characterized by comprising: an image acquisition unit which acquires image data of the front landscape, including the track; a coating color determination unit which determines, on the basis of information acquired by the image acquisition unit, the color of a coating material to be coated on the track; and a coating unit which coats the coating material onto the track.
