The application of UAV remote sensing technology in the monitoring of downslope slag

This paper explores the application of unmanned aerial vehicle (UAV) remote sensing technology in the monitoring of downhill debris flow during the construction of pumped storage power stations. The composition of UAV remote sensing systems, data acquisition and processing procedures are introduced, and their advantages and limitations are analyzed. In response to the shortcomings of traditional monitoring methods, a debris extraction method based on UAV remote sensing imagery is proposed. Experimental validation demonstrates the excellent performance of this method in terms of debris area similarity and overlap, confirming the feasibility and effectiveness of UAV remote sensing technology in downhill debris flow monitoring. Although there is room for improvement in accuracy, with further optimization, UAV remote sensing is expected to become an important technical tool for downhill debris flow monitoring, providing support for the safety management of pumped storage power station construction.
