无人机技术在地形测量中的应用分析

Application Analysis of Drone Technology in Terrain Measurement

无人机测量技术由于其自身的高效性和准确性,在地形测量中得到广泛运用。本文针对无人机测量技术中的空中三角形理论和数据处理模型进行分析,结合实际工程对无人机测量中控制点的设置方案进行了研究,指出了最合适的控制点布置方案。通过对比不同控制点设置方案误差可知,测量区域四边形的四角设置控制点,内部设置部分控制点的布设方案精度最高,外业工作量小,是最优布设方案。

UAV measurement technology is widely used in topographic survey because of its efficiency and accuracy.This paper analyzes the aerial triangle theory and data processing model in UAV measurement technology,studies the setting scheme of control points in UAV measurement combined with practical engineering,and points out the most appropriate arrangement scheme of control points.By comparing the errors of different control point setting schemes,it can be seen that the setting of control points at the four corners of the quadrilateral in the measurement area,and the layout scheme with some internal control points has the highest accuracy and small field workload,which is the optimal layout scheme.
