低空无人机目前已广泛应用于定点监控、高压线路监察、影视航拍、武警消防、空中监测、地理勘察等领域。而随着飞行控制、航空摄影、无线传输等子系统的逐渐完善，低空无人机也逐步成为小范围、高精度、实时、快速城市测量的重要平台。在城市测量中由于起飞场地的限制，小型固定翼飞机起飞与回收的安全性很难保证，而旋翼无人机却可以垂直起降，并能空中悬停，其不受起飞场地的限制，也利于获取清晰准确的影像信息。为此，本文简述了城市测量中基于六旋翼无人机信息获取系统的功能模型及其特点，分析了相关的关键技术，并对其精度进行测试，测试结果表明，六旋翼无人机在天气状况良好，像控点密度、分布符合要求的情况下，基本可以满足1∶500城市测量地形图的要求。
低空無人機目前已廣汎應用于定點鑑控、高壓線路鑑察、影視航拍、武警消防、空中鑑測、地理勘察等領域。而隨著飛行控製、航空攝影、無線傳輸等子繫統的逐漸完善，低空無人機也逐步成為小範圍、高精度、實時、快速城市測量的重要平檯。在城市測量中由于起飛場地的限製，小型固定翼飛機起飛與迴收的安全性很難保證，而鏇翼無人機卻可以垂直起降，併能空中懸停，其不受起飛場地的限製，也利于穫取清晰準確的影像信息。為此，本文簡述瞭城市測量中基于六鏇翼無人機信息穫取繫統的功能模型及其特點，分析瞭相關的關鍵技術，併對其精度進行測試，測試結果錶明，六鏇翼無人機在天氣狀況良好，像控點密度、分佈符閤要求的情況下，基本可以滿足1∶500城市測量地形圖的要求。

Low-altitude UAV has been widely used on sentinel surveillance ,monitoring of high-voltage wires ,television aerial ,armed police fire-fighting ,aerial surveillance ,geographical reconnaissance and etc .With the gradual improve-ment of flight control ,aerial photography and wireless transmission subsystems ,low-altitude UAVs have gradually become an important small-scale ,high-precision ,real-time and rapid urban measurement platform .Due to space limitations of the airports in the urban surveying ,the safe operation of small fixed-wing aircrafts is not guaranteed ,while rotor UAV which is not restricted by the airports ,can accomplish VTOL and mid-air hovering .Therefore ,more accurate and high definition footage can be easily achieved .Here ,the application of six-rotor UAV in urban surveying was introduced based on the functional model and its characteristics of the information acquisition system .The relevant key technology was ana-lyzed and its accuracy was tested .The test results indicate that the six-rotor UAV can basically meet the requirements of 1∶500 topographic mapping in urban surveying ,when the weather is good and the density and the distribution of the im-age-controlling points meet the requirements .
