Drone performance and imaging accuracy are improving dramatically, but drone flight is difficult in places where GNSS use is difficult or in densely populated areas. Therefore, a demonstration experiment was conducted in a two-by-four six-story full-scale experimental building, in which a drone was guided by a line and physically controlled so that the drone could move only between the start point and the end point. The significance is verified by comparing in terms of accuracy, safety, economy, and workability. As a result, when the damage caused by the fall or contact is considered to be large, the inspection work by the drone using the line guide type is considered to be useful.
