3D雷射掃描的應用與延伸－－以石化業為例

Application of 3D Laser Scanning in Oil & Gas Industry

各類型的工廠在營運啟動之後，可能因為擴建、製程改善，或設備汰換等等需求，而更改廠區的配置。然而管線設備更改後，一旦年代久遠，物件需要維修，卻尋不著現況圖資，勢必大為增加維護的時間與人力成本。因此，廠區異動後，皆應更新現況資料。
3D雷射掃描技術能有效率地進行廠區現況掃測。相較傳統測量技術，能以更少人力快速取得大量3D座標（即點雲），掃描時不必中斷工廠運作，有效取得大量管線資料，節省人力及時間成本。
本論文延伸應用點雲於模型建置，將具有實際尺寸資料的模型套繪於原始平面設計圖，便於一目瞭然管線設備的異動。除了細部的模型對照，亦製作3D環景導覽系統，可以即時遠端瀏覽廠區的全貌，並任意取得各點的空間座標及尺寸。
3D雷射掃描及其應用項目，對於複雜廠區的設備及管線檢測，不只實用亦有效減少維護成本。本文將以石化業為範例，進行詳細的說明。

Over the years, most industrial facilities have undergone various changes and modification which has increase its complexity to a stage where the general assembly and isometric drawings are out of date and do not reflect the actual state of the facility.
Traditionally, series of site visits and drawings which are expensive and time consuming will be required to accurately capture the as built configuration of these facilities to update all the drawings.
3D Laser Scanning is a relatively new revolutionary survey technique that provides the most cost effective solution for piping data acquisition within shortest practical time frame with high level of accuracy and detail providing a wide range of possibilities for data analysis and usage. The survey yields digital data sets, which are basically dense“point clouds”that can be registered and geo-reference to the real coordinate system for subsequent data analysis and intelligent modeling.
This paper aims to illustrate the application of 3D laser scanning in the oil and gas industry to produce intelligent 3D models and P&ID and 3D panoramic image view“Truview”.
