Open pit mines for limestone mining require rapid development of technologies and efforts to prevent safety accidents due to rapid deterioration of the slope due to deforestation and rapid changes in the topography. Accurate three-dimensional spatial information on the terrain should be the basis fo...

무인항공기를 통한 3차원 지형정보의 생성은 어떤 장점이 있는가? | las)의 수치지형모델을 생성하였다. 무인항공기를 통한 3차원 지형정보의 생성은 기존의 측량방법에 비해 빠른 속도의 데이터 취득이 가능하며, 소프트웨어를 이용한 자동화된 자료처리를 통해 성과물을 효과적으로 생성할 수 있다. Fig. | |
노천광산의 장단점은 무엇인가? | 노천광산은 대부분 광산의 규모가 크고, 고지대에 위치한다. 노천광산의 장점은 갱내채굴에 비해 회수율이 높고, 생산성이 높다는 것이며, 단점은 환경의 파괴가 크고, 날씨의 영향을 받는다는 것이다(Bae et al., 2018; Lee, 2018; Lee and Sung, 2018; Lee et al. | |
사진과 3D 레이저 스캐닝 방법으로 생성된 지형모델의 정확도 결과에서, 두 방법 모두 무엇을 만족하는 결과를 나타냈는가? | 사진과 3D 레이저 스캐닝 방법으로 생성된 지형모델의 정확도는 각각 11cm와 8cm 정도로 나타났다. 3D 레이저 스캐닝 방법이 다소 높은 정확도를 나타내었으며, 두 방법 모두 축척 1:1,000 수치지형도의 허용정확도를 만족하는 결과를 나타내어 노천광산의 지형정보 구축에 충분히 활용이 가능할 것으로 판단된다. Table 3은 축척 1:1,000 수치지형도의 허용 정확도를 나타낸다. |
