結合UAV與Mobile LiDAR等各式測量技術應用於快速3D影像展示之研究

本研究首先針對無人飛行載具系統（Unmanned Aerial Vehicle System, UAS）所獲取的影像資料處理，輔以全球導航衛星系統（Global Navigation Satellites System, GNSS）之快速靜態觀測為參考，利用車載光達（Mobile LiDAR）與虛擬基準站即時動態定位技術（electroncial-Global Navigation Satellites System, e-GNSS）兩種測繪技術做為檢核控制，且進行幾何高差之精度比較分析，藉以探討無人飛行載具（Unmanned Aerial Vehicle, UAV）影像高程於不同區域之差異性，期能快速獲得大面積幾何高程數據，並提升觀測成果精度。其次結合上述數值測量技術，快速將研究區域内之平面影像以三維（Three-Dimensional, 3D）形式立體化展示，提供3D立體空間訊息。本研究透過Mobile LiDAR、e-GNSS、GNSS及UAV等測量技術實施高程資料的分析比較與檢核，驗證Mobile LiDAR法於測量作業的實用性，並利用3ds Max通用軟體中的兩種方法，製作3D模型及影像紋理貼圖，於25-29小時内快速展示3D圖台，其成果均具備LOD2的層級。

This research, primarily, is about image processing of air photos acquired from UAS (Unmanned Aerial Vehicle System), technology of rapid static GNSS(Global Navigation Satellites System) technology as reference, using Mobile LiDAR and e-GNSS (electroncial-Global Navigation Satellites System) for controlling recognition and analysis of geometric heights precision in the imagery. Moreover, by investigating the geospatial differences of UAV (Unmanned Aerial Vehicle) imagery heights in various areas in order to quickly obtain geometric elevation data in large areas and improve the accuracy of observation results. Secondly, combined with the results from the above digital surveying techniques, the 2D imagery can be rapidly transformed and represented as 3D geospatial information in the study areas. In this research, Mobile LiDAR, e-GNSS, GNSS and UAV methods were applied to analysis and comparison of elevation data. It is confirmed that Mobile LiDAR method is a practical tool in surveying operations with combination of UAV technology. Because of two methods in 3ds Max used, 3D modeling and image texture mapping can in 25-29 hours quickly display the 3D graphics and the achievement haves the grade of LOD2.
