Examination of Railway Structure Inspection Method from Aerial Tracks Using the Automatic Navigation Function of UAV

Abstract

In the event of a disaster, we conducted a demonstration test of track inspection using a UAV. As a result, it was possible to fly over the track with the automatic navigation function. In addition, it was possible to grasp the presence or absence of abnormalities from the air. The acquired data can be checked immediately after flight from videos and still images, and by converting them into a point cloud, it is possible to grasp the approximate dimensions.
