摘要

以無人載具（Unmanned Aerial Vehicle, UAV）進行近景攝影，可快速精準地掃描與紀錄，精確地測量物體的大小、高度，以利製作精細的三維模型，更可透過電腦計算產生三度的虛擬空間。在景觀、建築、土木工程方面都有相當高的應用價值，然而在景觀規劃設計領域尚未進行深入的探究。本研究以UAV輔助景觀調查為出發點，以雲林縣西螺鎮廣興社區、高雄市大樹區龍目社區為研究地點。首先，以UAV近景攝影，分析UAV航線規劃對於正射影像與三維模型之品質的影響；其次，比較UAV與傳統景觀調查之差異。研究結果提出以無人載具進行景觀調查之流程、最佳正射影像與三維模型之航線規劃建議，研究成果有助於UAV於戶外景觀規劃與設計實務之應用，具有學術與實用價值。

Unmanned Aerial Vehicle (UAV) is useful for measuring the size of landform and product high resolution three-dimensional landscape models. It has wildly application to landscape, architecture, and civil engineering field. In this work, we will focus on how to apply UVA to landscape survey. Two study areas are Guangxing Community and Longmu Community. Firsly, we take photographies through different routes and parameters set at two communities by UAV. Then, comepare imagine and 3D model quality among different routes. Results show that UAV fly heigh is 60-100 meters, S type fly route, and 70-80% photo overlap ratios could get the highest accuracy image. We also point out benefits of apply UVA to landscape survey compare with traditional survey methodology. Conclusions of this work provide useful processes and fly parameters for using UAV to landscape survey.
