摘要

近年來隨著科技之進步，無人航空系統與無人飛行載具技術快速發展，無人飛行載具的飛行穩定度比起以往大幅的提升，使用無人飛行載具進行航空攝影測量，可快速地取得災害事故現場第一時間的受災影像資訊，並快速製作災區正射影像圖資供後續救災及緊急處理參考與應用。正射影像圖資是將航拍影像上的像點高差和影像傾斜位移移除，可提供正確的幾何與輻射資訊作地理資訊的底圖，或套疊數值高程模型作為三維地形模擬供相關研究之用。本研究透過三種影像拼接軟體進行知本森林遊樂區之正射影像拼接，比較正射影像成果之品質與均方根誤差，供後續相關研究參考。

In recent years, with advances in technology, the Unmanned Aircraft System and Unmanned Aerial Vehicle technology and rapid development, significantly improved flight stability of Unmanned Aerical Vehicle than ever before, the use of Unmanned Aerial Vehicle aerial photogrammetry, can quickly obtain disaster scene of the accident first time images of disaster information and rapid production of the affected areas Ortho-Photo and emergency relief funding for subsequent processing and application of reference. Orthophoto map data is the dot height and tilt of an image displacement aerial image on removal, which provides the correct geometry and radiation information as basemap of geographic information, or nested numerical simulation of three-dimensional terrain and elevation model as for related research purposes. This study was performed orthophoto mosaic Chihpen Forest Recreation Area through the three image stitching software, compare the quality of the outcome of the orthophoto and root mean square error, a reference for subsequent research.
