Abstract

To improve the monitoring of Coastal Debris in the South Korea, which is difficult to estimate due to limited resources and vertex-based surveys, an approach based on UAV(Unmanned Aerial Vehicle) images and the RT-DETR(Realtime DEtection TRansformer) model was proposed for detecting Coastal Debris. By comparing to field investigation, the study suggested the possibility of quantitatively detecting coastal garbage and estimating the total capacity of garbage deposited on the natural coastline of the South Korea. The RT-DETR model achieved an accuracy of 0.894 for mAP@0.5 and 0.693 for mAP@0.5:0.95 in training. When applied to unmanaged coasts, the accuracy for the total number of coastal debris items was 72.9%. It is anticipated that if guidelines for defining monitoring of unmanaged coasts are established alongside this research, it should be possible to estimate the total capacity of the deposited coastal debris in the South Korea.

한정된 정점과 인력 기반의 조사로 실제 국내 표착되는 해안 쓰레기의 총용량 추정이 어려운 우리나라의 해안 쓰레기 모니터링 방식 개선을 위해 비관리 해변에서 UAV(: Unmanned Aerial Vehicle) 이미지와 RT-DETR 모델을 기반으로 해안 쓰레기 탐지하고 현장 조사와의 비교 연구로 해안 쓰레기의 정량적 탐지 및 자연 해안선 기준 우리나라에 표착되는 전체 쓰레기 총용량 추정 가능성을 제시하였다. RT-DETR(: Realtime DEtection TRansformer) 모델 학습 결과 mAP@0.5는 0.894, mAP@0.5:0.95는 0.693의 정확도를 보였다. 모델을 비관리 해변에 적용한 전체 해안 쓰레기 개수에 대한 정확도는 72.9%로 나타났다. 본 연구와 비관리 해변에 대한 모니터링을 정의하는 관리지침 마련 연구가 동반된다면 우리나라에 표착되는 전체 해안 쓰레기의 총 용량 추정이 가능할 것으로 기대된다.
