Abstract

In this study, data on the study site for apartment construction was acquired, and the quantity of construction waste was calculated using a drone and mobile 3D laser scanner. The accuracy of the drone was 0.034 to 0.064m in the horizontal and vertical directions, respectively, and the mobile 3D Laser Scanner showed an accuracy of 0.018 to 0.049m in the horizontal direction, respectively. These results suggest that it is possible to construct spatial information using a drone and mobile 3D laser scanner with a value within the allowable accuracy of 1:1,000 digital terrain. The volume of construction waste calculated using the mobile 3D laser scanner data was 70,797㎥. It was possible to calculate the volume on the side of the building or some facilities that appeared as shaded areas in the drone outcomes. In addition, modeling was performed for view analysis of the apartments scheduled to be constructed and the terrain-based modeling results of the surrounding buildings. In the future, data construction and accuracy evaluation using mobile 3D laser scanners will be conducted. In addition, additional research comparing existing methods and work processes will be carried out, and the efficiency of mobile 3D laser scanners in the field of spatial information construction can be presented.

본 연구에서는 드론과 이동형 3D 레이저 스캐너를 이용하여 아파트 건설을 위한 철거현장의 데이터를 취득하고, DEM을 구축하였으며, DEM을 활용하여 건설폐기물의 물량을 산출 및 조망분석 등 공간분석을 수행하였다. 데이터의 신뢰성 확보를 위해 정확도 평가를 수행하였으며, 정확도 평가 결과 드론은 수평 및 수직 방향 0.034~0.064m로 나타났으며, 이동형 3D Laser Scanner는 수평방향 0.018~0.049m의 정확도를 나타내었다. 이러한 결과는 1:1,000 수치지형도 허용정확도 이내의 값으로 드론 및 이동형 3D 레이저 스캐너를 이용한 공간정보 구축이 가능함을 나타낸다. 이동형 3D 레이저 스캐너 데이터를 이용하여 계산된 건설폐기물의 물량은 70,797㎥이었으며, 드론 성과물에서 음영지역으로 나타난 건물 측면이나 일부 시설물에 대한 물량의 산출이 가능하였다. 또한 건설예정인 아파트의 조망분석을 위한 모델링을 수행하였으며, 주변 건물 및 건설예정인 아파트에 대한 지형 기반의 모델링 결과는 조망분석을 위한 자료로 활용이 가능하였다. 향후 이동형 3D 레이저 스캐너를 이용한 데이터 구축 및 정확도 평가와 함께 기존 방법과 작업공정을 비교하는 추가 연구가 이루어진다면 공간정보 구축 분야에서 이동형 3D 레이저 스캐너의 효율성을 제시할 수 있을 것이다.
