본 논문의 목적은 건축물을 드론으로 계측하여 드론의 비행 및 촬영 변수에 따른 계측 정확도를 분석하는 것이다. 드론의 비 행 및 촬영 변수는 비행고도 3가지(50m, 60m, 70m), 중복도 4가지(60%/60%, 60%/80%, 80%/60%, 80%/80%), 카메라 각도 2가지(45°, 90°), 속도 2가지(2m/s, 최고속도)이며, 총 48번을 계측하였다. 드론으로 계측하여 얻은 3D 데이터와 실제 건축물의 길이를 비교하였으 며, 드론의 비행 속도가 느릴수록 정확도가 높게 나타났다.
The purpose of this paper is to analyze the measurement accuracy according to the drone’s flight and shooting parameters by measuring the building with the drone. The flight and shooting parameters of the drone are 3 types of flight altitude (50m, 60m, 70m), 4 types of overlap (60%/60%, 60%/80%, 80%/60%, 80%/80%), 2 types of camera angle (45°, 90°) and two speeds (2m/s, maximum speed), and a total of 48 measurements were made. The 3D data obtained by measuring with the drone and the actual length of the building were compared, and the slower the drone's flight speed, the higher the accuracy.
