天狼星无人机免像控技术在河道整治中的应用

针对河道带状复杂的地形条件及高精准的测量要求，提出了采用天狼星无人机航空测图系统进行地形图测绘的方法，并用实例进行了验证。验证结果表明，天狼星无人机航测系统通过其内置100Hz实时动态差分RTK技术和高精度惯性导航IMU系统，很好地解决了照片匹配等问题，在不需要布设像控点的情况下获取高精度的影像数据，大大提高了航测效率；同时河道整治过程中所遇到的土方量计算、洪水分析等问题将得到更加精确直观的呈现，为后续河道综合整治工作提供了精准的数据支持。

Application of the Sirius Non-GCPs UAV in River Regulation

As to the problem that the river band complex terrain conditions and measurement of high precision requirement , the paper puts forward the method of Sirius UAV aerial mapping system for topographic mapping .According to this method , Sirius unmanned aerial system using its built-in 100 Hz real-time dynamic RTK technology and high precision of inertial navigation system IMU , can solve the problem of photo matching in the image data , without layout control points as the case to obtain high precision , greatly improving the efficiency of aerial survey .At the same time, the earthwork calculation and flood analysis in the process of river regulation will become more accurate and intuitive , which provides accurate data support for the subsequent comprehensive river regulation work .
