摘要
本文对无人机在淮河航道管理的应用场景进行了分析,阐述了光束法空中三角测量的原理,并对3种图像得到的实际测量数据进行了统计分析。结果表明,基于综合图像的测量,在平面测量和高程测量方面精度最高;基于正视图像的测量精度次之;基于倾斜图像的测量精度最低。随着基准点数量的增加,3种图像的测量精度得到了明显的改善。
This paper analyzes the application scenario of UAV in Huaihe River waterway management, expounds the principle of beam aerial triangulation, and makes a statistical analysis of the actual measurement data obtained from three kinds of images. the results show that the measurement based on comprehensive images has the highest accuracy in plane measurement and elevation measurement;the measurement accuracy based on orthographic images is next;the measurement accuracy based on oblique images is the lowest. With the increase of the number of reference points, the measurement accuracy of the three kinds of images has been significantly improved.
