Title:
SYSTEM, METHOD, AND PROGRAM FOR USING UNMANNED AIRCRAFT TO ESTIMATE ROTOR DIRECTION/AZIMUTH OF WIND POWER GENERATION DEVICE, AND STORAGE MEDIUM STORING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/188378
Kind Code:
A1
Abstract:
Provided is a subsystem for using an unmanned aircraft provided with an imaging device to estimate the direction of a rotor of a wind power generation device, the rotor comprising a first blade and a second blade. The subsystem is provided with a position information acquisition unit for acquiring: in an image captured by the imaging device, position information for a first position of the unmanned aircraft that has been moved to the first position at which a distal end of the first blade and a distal end of the second blade substantially match; and in an image captured by the imaging device, position information for a second position of the unmanned aircraft that has been moved to the second position which is different from the first position and at which the distal end of the first blade and the distal end of the second blade substantially match. The subsystem is also provided with a rotor direction estimation unit for estimating the direction of the rotor of the wind power generation device on the basis of the position information for the first position and the position information for the second position.
