해상 유인등대 및 무인표지에 설치된 등명기의 경우, 선박들의 안전한 항해를 위해 항상 일정 기준 이상의 빛을 발광해야 한다. 대한민국 해양수산부에서는 주기적으로 등명기 광학 특성을 검사하여 계속 사용 여부를 판단하고 있다. 중대형 등명기는 철거 및 운반이 어려워 항로표지 측정선을 활용하여 실외환경에서 검사하고 있으나, 인적·물적 비용과 파도에 의한 오차가 크게 발생할 수 있다. 본 연구에서 항로표지 측정선의 단점을 보완하기 위해 드론을 이용하여 광도를 측정하는 새로운 방법론을 개발하였다. 또한, 오동도등대를 대상으로 드론을 이용하여 광도를 측정하고 시뮬레이션을 수행하였으며, 기존 측정방식 대비 평균 5.17% 오차가 발생했다. 드론을 이용한 광도측정 방법은 향후 항로표지 측정선을 활용하면서 발생하는 단점을 최소화할 수 있을 것으로 기대한다.
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.
