无人机低空摄影测量大比例尺测图精度研究
Research on the Precision of Large Scale Mapping in Low Altitude Photogrammetry of UAV

无人机航空摄影测量在许多行业都得到了广泛应用，空三解算精度直接影响4D产品的精度，像控点的布设是影响空三解算精度的关键因素之一。本文在较密集的控制点方案的基础上，对控制点进行了抽稀试验，研究了不同控制点方案对空三精度的影响。
Unmanned aerial photogrammetry has been widely used in many industries, and the accuracy of aerial triangulation directly affects the accuracy of 4D products. The layout of image control points is one of the key factors affecting the accuracy of aerial triangulation. On the basis of a relatively dense control point scheme, this article conducted a dilution test on the control points and studied the impact of different control point schemes on the accuracy of the air conditioning system.
