中文摘要 |
本研究以搭載不同衛星定位模組市售測繪級與消費級無人飛行載具,進行測量成果誤差比較分析,選定宜蘭力霸產業道路旁崩塌地進行四期的空拍作業,並透過質點影像測速法(Particle Image Velocimetry, PIV)進行分析,探討兩者所產製的正射影像成果之不確定性,同時也透過現場量測的RTK資料與影像空間資訊做比對,以評估影像之可能誤差規模,並了解市售測繪級與消費級無人飛行載具之差異;另案例探討選定桃園市復興區光華農道崩塌,藉由空拍建模及透過質點影像測速法分析,獲知崩塌整體移動方向及變量,作為崩塌調查及活動性參考資料。 |
英文摘要 |
In order to understand the error results of unmanned aerial vehicles equipped with different satellite positioning modules, in the first stage of this study, the shallow landslide next to Liba Industrial Road in Donshang District, Yilan Country was selected to conduct four times of landslide investigation. Then, analyzed error and stability of the orthoimage produced by the two UAV through the Particle Image Velocity method (PIV). At the same time, the RTK data measured on-site was compared with the orthoimage spatial information to evaluate the possible error scale of the orthoimage. In the second stage, the landslide at Guanghua Agricultural Road in Fuxing District, Taoyuan City, where has been relatively active, was conducted for modeling and analysis through Particle Image Velocity. This was used to determine the movement direction and variables of the landslide as a reference for investigation. |
