Abstract

The various studies and applications for UAVS(Unmaned Aerial Vehicle System) have been recently increased as a new technology to create 3D spatial information rapidly and accurately. UAV(Unmanned Aerial Vehicle) is economical when comparing with conventional technique, such as satellite and aerial survey, and can quickly obtain high resolution data under 5cm. This paper examined the utilizing possibility to creating 3D spatial information and analysis the compatibility the UAV data obtained by non-metric digital camera with conventional numerical photogrammetric system. The DEM and normal orthophoto is created by exclusive S/W and DPW(Digital Photogrammetry Workstation) then analysis the accuracy of created data. As a result, the accuracy of the created DEM and normal orthophoto, which is obtained by UAV then processed by DPW, is not satisfied;so it is estimated that the compatibility the UAV data with conventional numerical photogrammetric system is low.

최근 무인항공기(UAV : Unmaned Aerial Vehicle)는 신속하고 정확하게 3차원 공간정보를 구축하는 새로운 기술로 다양한 분야에서 연구와 활용이 증가하고 있다. 이러한 무인항공기는 위성측량이나 기존 항공측량에 비해 경제적이며 5cm급 이하의 고해상도 영상을 편리하게 취득할 수 있다는 장점을 지니고 있다. 따라서 본 논문에서는 무인항공기와 비측량용 디지털 카메라를 이용하여 3차원 공간정보의 제작 가능성과 기존 수치사진측량 시스템과의 호환성 분석을 위하여 무인항공기 전용 S/W 및 DPW(Digital Photogrammetry Workstation)를 이용해 성과품인 수치표고모델과 정사영상을 제작하고 정확도 분석을 수행하였다. UAV 전용 S/W와 DPW로 제작된 수치표고모델과 정사영상의 정확도 분석 결과 UAV 자료와 기존 수치사진측량 시스템과의 호환성은 낮은 것으로 판단된다.
