Abstract
In the case of lantern fixtures installed on manned marine lighthouses and unmanned beacons, they must always emit light above a certain standard to ensure the safe navigation of ships. The Ministry of Oceans and Fisheries of the Republic of Korea periodically inspects the optical characteristics of lanterns to determine whether they should continue to be used. Middle and large-sized lanterns are difficult to dismantle and transport, so they are inspected using a buoy tender. However, significant human and material costs, as well as errors due to wave conditions, can occur. This study developed a new methodology for measuring luminous intensity using drones to overcome the limitations associated with buoy tenders. Additionally, the luminous intensity of the Odongdo lighthouse was measured using drones, and simulations were conducted. As a result, an average error of 5.17% was observed compared to the conventional measurement method. The luminous intensity measurement method using drones is expected to minimize the drawbacks associated with the use of buoy tenders in the future.
Key Words: Aid-to-Navigation, drone, photometry, visual signaling, lighthouse, lantern
