水庫是台灣重要的集水設施，為了維護水庫集水區周邊的環境，本研究利用多旋翼無人機作為拍攝工具進行環境作業監測與環境差異調查分析，隨著無人機的運用日新月異，較不受天候與空域影響，尤其是運用在颱風過後多雲的天氣時，可執行災害現場的拍攝任務，並且得到即時的救災資訊，同時也不用耗費較多的人力資源，也可取得較佳的影像品質。本次研究通過拼接後的正射影像，來分析土地崩塌變異情形，再套疊潛勢邊坡變異進行現況分析，後續可提供給管理單位作為調查與監控之參考。最後通過比對人工目視及無人機拍攝這兩種方法，分析人力、時間和金錢成本效益，達到效益最大化。

Reservoirs are essential to water collection in Taiwan. In order to maintain the environment around the water catchment area of the reservoir, this research used multi-rotor drones as the image-capture tool for environmental monitoring, environment differential investigation and analysis. With the rapid development of drones, drone operations are relatively unaffected by the weather and airspace. Especially in cloudy days after typhoon, we can obtain instant information of disaster, reducing the manpower required to have better image quality simultaneously. In this study, we used spliced orthophotos to analyze the landslides variation. Through overlapping the potential slope variation, current situation analysis can be provided to the management unit as the reference for investigation and monitoring. Eventually, comparing the methods of manual visual inspection and unmanned aerial vehicle shooting, the effectiveness of manpower, time-consuming were analyzed to maximize the benefits.
