In the present study, the interior orientation parameters were computed by using various kinds of methods. Five DSMs (Digital Surface Models) in total were produced by applying interior orientation parameters to the image processing, and the accuracy was evaluated. In order to use interior orientati...

카메라 검정이란? | 왜곡을 일으키는 카메라를 통하여 촬영된 영상과 대상공간과의 기하학적 모델을 수립하기 위해서는 카메라와 렌즈의 특성을 알아야 하며 이와 같은 과정을 통해 내부표정 요소를 계산하는 일련의 과정을 카메라 검정(Calibration)이라고 한다. 특히 카메라의 화소 및 이미지 센서 크기와 같은 정량적 파라미터 외에 렌즈에 대한 초점거리와 방사왜곡량과 같이 사진측량을 위해 필요한 내부표정 요소인 정성적 파라미터를 계산하는 것이 카메라 검정이다(Won et al. | |
UAS 연구의 주를 이룬것은 무엇인가? | UAS 연구는 그 목적에 따라 분석 대상이 다르지만 기본적으로 영상처리의 결과물인 DSM의 정확도를 검증하는 연구가 주를 이뤘다(Sebastian and Jochen, 2014; Tonkin et al., 2014; Kim et al. | |
UAS 연구는 어떤 것이 있는가? | , 2015). 초기에는 단편적인 DSM의 정확도 검증에 그쳤지만 자료가 축적되면서 결과물을 시계열적으로 분석한 연구도 진행되었다(Yu etal., 2016; Turner et al., 2016). 정사영상과 DSM 외에도NDVI(Normalized Difference Vegetation Index, 정규식생지수)와 열화상과 같은 영상자료를 획득하고 이를 검증하는 연구도 발표된 바 있다(Gini et al., 2012; Nishar et al., 2016). 또한 토양 침식량 계산과 지질학적 단층 및 작물의 작황 분석 등 다양한 분야에서 UAS를 통해 제작한 결과물을 연구에 활용하고 있다(Peter et al., 2014; Luna and Lobo, 2016; Vollgger and Cruden, 2016). |
