中文摘要 | 目前臺灣各地政機關在比例尺1/1200未辦地籍整理地區土地複丈測量作業時,常遭遇地形地物遮蔽而無法通視觀測,或因地形限制致人員無法到達施測等問題。本研究規劃於新北三峽橫溪地區已辦地籍整理之佳興段與未辦地籍整理區域為航拍作業區域,應用無人飛行載具(Unmanned Aerial Vehicle,UAV)搭載高解析度相機,結合使用內政部國土測繪中心建置之e-GNSS即時動態定位系統,透過航拍製作正射影像解決此一問題。研究結果顯示,以UAV航拍製作正射影像,經驗證符合未辦地籍整理地區測量精度36cm之要求,並比較研究案例範圍測量作業時間,以UAV航拍正射影像執行現況測量需時約5至7天,相較於傳統以地面儀器執行現況測量作業方式則需時約12至41天,更具效率。未來各地政機關在未辦地籍整理地區土地複丈測量作業時,應可利用UAV航拍製作正射影像技術來解決未辦地籍整理地區傳統現況測量問題。 |
英文摘要 | During land resurveying performed in the unregistered cadastral area, it is often encountered obscured situation in observation, or hard to reach the survey area due to terrain limitation. In this study, an unmanned aerial vehicle (UAV) equipped with a high-resolution camera and the e-GNSS real-time dynamic positioning system built by the Ministry of the Interior's National Land Surveying and Mapping Center to produce orthophotos for land resurveying at Chia-Hsin section in New Taipei City. The results show that the geometric accuracy for the orthophoto results had been validated better than 36 cm according to mapping requirement in the unregistered area. Moreover, the working time for the land resurveying based on orthophoto products can be reduced effectively to five to seven days, but it needs 12 to 41 days worked in the same area by using traditional terrestrial surveying methods. Therefore, the UAV aerial surveying method can be conducted to improve performance on the land resurveying in the unregistered cadastral area. |
