摘要
无人机航摄技术因其数据采集快、地形适应好、可视化程度高等优点,被广泛应用于水利、公路、桥梁等领域。对于土石坝的运行管理,高精度的大坝模型对评估坝体运行状态及后续相关研究至关重要。本文以方田坝为例,采用无人机航摄技术进行土石坝高精度建模研究,并与三维激光扫描数据进行对比,发现无人机航摄技术能有效提高数据采集和处理效率,具有机动灵活、效率高、精度高的优点,能满足土石坝高精度建模需求。
Due to its rapid data acquisition,excellent terrain adaptability,and high level of visualization,Unmanned Aerial Vehicle(UAV)photogrammetry technology has been extensively applied in fields such as water conservancy,highways,and bridges.In the operational management of earth-rock dams,high-precision dam models are crucial for assessing the operational status of the dam body and subsequent related research.Taking Fangtian Dam as an example,this paper conducts research on high-precision modeling of earth-rock dams using UAV photogrammetry technology and compares the results with terrestrial laser scanning data.The findings reveal that UAV photogrammetry technology can effectively enhance data acquisition and processing efficiency,offering the advantages of mobility,flexibility,high efficiency,and high accuracy.It meets the requirements for high-precision modeling of earth-rock dams.
