摘 要 隨著科技的日新月異的進步,無人載具的發展在近年來逐漸受到重視,無人載具可運用之範疇非常的廣闊,如:軍事調查、航空拍攝、古蹟探索、災區搶救、安全監控…等多方面的應用。在本研究中運用無人飛行載具執行航空攝影測量,建置數值地形模型以及正射影像,透過成果分析判釋知本森林遊樂區段之地形變化。 知本森林遊樂區段於莫拉克風災時受到嚴重打擊,有不少的住戶受到嚴重傷害,本研究運用100年DTM與攝影測量產製之DSM進行河道高程變化比較評估,各河道區段皆有明顯的淤積情況發生,於剖面5的地形變化中更可看出河道有明顯約40公尺的堆積高度。 透過本研究成果証實無人載具之便捷性及即時性,往後可將無人載具廣泛運用於救災與重建工作上,使救災人員與工程單位人員的生命安全受到更進一步的保障。 關鍵字: 無人飛行載具、攝影測量、數值模型、地形比較
Abstract With the rapid advancement of technology, the development of unmanned vehicles in recent years, increasing attention, unmanned vehicle can use category is very broad, for example: military survey, aerial photography, exploring the historic monuments, the disaster rescue, security monitoring, and other applications. In this study, the use of unmanned aerial vehicles perform aerial photogrammetry, digital terrain model building and merging orthophotos, through the analysis result of Chihpen Forest Recreation Area terrain change. Chihpen Forest Recreation Area subjected to a severe blow when Morak hurricane, many households have been seriously hurt, in this study, use of DTM by 100 year production and Photogrammetry production DSM to compare and assess the river elevation changes, each section of the river occurs significant deposition, in the river cross-sectional 5 can be seen a significant accumulation of about 40 meters height. In this study, unmanned vehicles confirm that immediacy and convenience. In the future, unmanned vehicles can be widespread use in relieving and rebuilding work. In that case, the safety of rescuers and engineering personnel is further protected. Key words: Unmanned aerial vehicle, Photogrammetry, Digital model, Terrain compared
