摘要
无人机系统已经广泛地应用于各个领域,但在现代河流地貌研究中的应用较少。本文简要介绍了无人机的应用现状,总结了其主要应用步骤。首先,建立合适的飞行任务,采集一定的地面控制点;然后,获取无人机影像数据,处理无人机数据;最后生成DSM和DOM数据。基于以上方法对半滩子河进行三维地貌建模,最终得到高精度的辫状河模型,为河流动力学研究提供了准确的河流形态学参数。
Unmanned aerial vehicles (UAVs) systems have been widely used in various fields, but they have fewer ap plications in modern river geomorphology research. This paper briefly introduces the application status of drones, and summarized their main application steps. First, a suitable flight mission was established, and a certain ground control point (GCP) was collected;then, the drone image data was acquired and the drone data was processed;finally, DSM and DOM data were generated. Based on the above methods, a three-dimensional geomorphological model of Bantan zi River was obtained, and a high-precision braided river model was finally obtained, which provided accurate river morphological parameters for the study of river dynamics.
