Abstract

These days, inexpensive and high efficiency UAV of disaster prevention and spatial information has been given more attention. But studies about test of accuracy of UAV were not enough despite high interest. This research produced DSM and ortho photo and estimated accuracy by comparing coordinates with GNSS survey to evaluate outcome of fixed wing UAV. The ortho photo was found to make use of it to update 1/1,000 map. This research investigated spatial information construction using existing terrestrial LiDAR to suggest effectiveness of fixed wing UAV.

최근 재해 예방 및 공간정보 구축 분야에 경제적이고, 효율이 높은 무인항공기에 대한 관심이 증가하고 있다. 그러나 무인항공기에 대한 높은 관심에도 불구하고 이에 대한 정확도 검증이나 활용성 평가에 대한 연구는 충분히 이루어지지 못하고 있다. 이에 본 연구에서는 고정익 무인항공기를 이용하여 DSM과 정사영상을 생성하고, GNSS 측량과 비교하여 정확도를 평가하였다. 연구를 통해 무인항공기에 의한 정사영상은 축척 1:1,000 수치지도 갱신에 활용이 가능함을 제시하였다. 또한 지상라이다를 이용하는 방법과 인력 및 시간의 비교를 통해 고정익 무인항공기의 활용성을 평가하였다.
