Abstract
본 논문은 안전점검을 받아야 하는 시설물의 수가 급증하고 있는 상태에서 대안으로 대두된 무인비행장치의 안전점검 활용성을 검증하고자 한 연구로서, 안동댐을 테스트베드로 하여 무인비행장치 촬영 및 데이터 처리를 수행하고 그 결과를 정리하고 분석하였다. 연구결과 댐과 같은 시설물의 안전점검에 있어서 무인비행장치를 활용하기 위한 비행 및 촬영방법을 정립하였으며, 아울러 시설물 표면에 나타난 균열폭을 감지하기 위하여 실내실험을 통하여 탐지가능한 GSD를 확인할 수 있었다. 따라서 본 연구를 통하여 댐과 같이 규모가 큰 시설물도 무인비행장치를 활용한 안전점검이 가능하다는 것을 확인할 수 있었으며, 본 연구의 결과를 활용한다면 보다 효율적으로 시설물 안전점검이 가능할 것으로 기대된다.
This paper is a study to verify the usability of the UAV(Unmanned Aaerial Vehicle), which has emerged as an alternative in a situation where the number of facilities requiring safety inspection is rapidly increasing. For the study, Andong Dam was chosen as a test bed, so UAV photogrammetry and data processing was performed and the results were summarized and analyzed. As a result of the study, flight and filming methods were established to utilize UAVs in the safety inspection of facilities such as dams. And detectable GSD was confirmed through indoor experiments to detect crack widths on the surface of facilities. Therefore, through this study, it was confirmed that even large-scale facilities such as dams can be inspected using UAVs. If the results of this study are used, it is expected that more efficient facility safety inspections will be possible.
