UAV空拍數值模型於BIM景觀規劃應用之研究

對於景觀設計其最初須獲得設計區域地表狀況現地地形資料如數值地形模型（Digital Terrain Model，DTM）、數值高程模型（Digital Elevation Model，DEM）以及數值地表模型（Digital Surface Model，DSM）然而相關資料取得或需經過申請或需以現場量測方式獲得較為不便。近年UAV無人機之使用於空拍成果已逐漸普遍然而空拍照如何能轉換為工程所使用則為工程界所需處理之課題。目前對於空拍影像之處理如Pix4D、Bently Microsation、AutoDesk Recap等均為目前常見之空拍影像處理軟體。上述軟體中可將空拍影像化為空間雲點資訊可作為後續景觀規劃應用之依據。本文即透過UAV空拍成果建立地表模型並以Autodesk Revit site designer建立景觀設計相關設施以作為景觀規劃設計之參考。

For landscape design, it is necessary to obtain the surface conditions of the design area at first, on-site topographic data such as Digital Terrain Model (DTM), Digital Elevation Model (DEM) and Numerical Surface Model (DSM) However, related data It is more inconvenient to obtain it or to apply for it or to obtain it by on-site measurement. In recent years, the use of UAV drones for aerial photography has gradually become common, but how to convert aerial photography into engineering is a topic that the engineering community needs to deal with. At present, the processing of aerial imagery such as Pix4D, Bently Microsation, AutoDesk Recap, etc. are currently common aerial image processing software. In the above software, aerial photography can be converted into spatial cloud point information, which can be used as a basis for subsequent landscape planning applications. In this paper, the UAV aerial photography results are used to establish a surface model and establish related facilities for landscape design as a reference for landscape planning and design.
