초록

기존의 넓은 면적 지역에 대한 정사영상은 항공사진측량을 이용하였으나 이 방법은 작은 면적 지역에 대한 정사영상 및 짧은 주기의 지속적인 변화 관측 측면에서는 비경제적이다. 드론은 군사목적으로 개발되어 활용되었으나 최근 농작물 관리 및 분석, 방송 중계, 기상 관측 그리고 재난 조사등 다양한 분야에서 활용되고 있다. 이러한 드론은 가격이 비싼 상업용 드론을 이용한 사례가 많았다. 본 연구에서는 Orthomosaic과 DSM을 제작하기 위하여 소규모 지역에서 활용이 유용한 저가형 조립식 드론, 일반 디지털카메라와 오픈 소스 프로그램인 Mission planner를 이용하여 영상을 취득하고 후처리 작업은 Pix4d 소프트웨어를 사용하였으며 제작된 정사영상의 GCP는 각각 평균 오차 X 좌표는 3.4cm, Y 좌표는 2.4cm, Z 좌표는 4.2cm로 나타났다. 조립식 소형 드론은 소규모 지역에서의 조립식 드론은 빠르게 영상을 취득하고 다양하게 활용 할 수 있을 것으로 보인다.

Ortho images created by aerial photogrammetry have been used in large areas but they are uneconomical for small areas and continuous change observation. The drones have been developed for military purposes, and recently they are being used crop management and analysis, broadcast relay, meteorological observation and disaster investigation and so on. Also there were a lot of studies of expensive commercial drone. In this paper, lower price self-assembly drone usable for in small areas, Obtained images and produced Orthomosaic and DSM using mission planner which is a normal digital camera and open source program, and postprocessing was used Pix4d software. GCP errors are X-coordinate 3.4cm, Y-coordinate 2.4cm, Z-coordinate 4.2cm. It seems like the self-assembly drone can be used for various fields.
