Title:
STATE DETECTION DEVICE AND STATE DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/065216
Kind Code:
A1
Abstract:
In the present invention, an unmanned flight vehicle flies along a catenary curve, thereby detecting the state of an electric wire more accurately. The state detection device is equipped with: an imaging unit for capturing a scenery image showing the scenery around an unmanned flight vehicle; a catenary calculation part for calculating the catenary curve of an electric wire on the basis of an image of multiple structures included in the scenery image captured by the imaging unit and an image of the electric wire suspended between the multiple structures; a flight path calculation part for calculating a flight path of the unmanned flight vehicle along the catenary curve of the electric wire calculated by the catenary calculation part; a flight control part for controlling the flight of the unmanned flight vehicle on the basis of the flight path calculated by the flight path calculation part; and a state detection unit for detecting, during the flight of the unmanned flight vehicle along the flight path which is calculated on the basis of the catenary curve calculated by the catenary calculation part, the state of the electric wire for which the catenary curve is calculated, or the state of another electric wire which is suspended between the multiple structures suspending the electric wire for which the catenary curve is calculated. The state detection device is mounted on the unmanned flight vehicle.
