Abstract: UAV multispectral technology combines the mobility of UAV platforms with the rich information dimensions of multispectral data, enabling efficient object identification and dynamic monitoring at centimeter-level spatial resolution. It has demonstrated significant application value in fields such as agriculture, environmental monitoring, and surveying. Low-altitude remote sensing data acquired by UAVs offer advantages such as strong timeliness, minimal atmospheric radiation interference, high spatial resolution, large data volumes, and excellent data quality. This technology achieves high precision in detecting and identifying types of ground objects, measuring and evaluating material content reflected in spectra, delineating spatial distribution of ground objects, and monitoring changes in ground objects. Its application in mine geomorphological monitoring has opened up a new avenue for ecological environment monitoring in traditional mining areas, thereby reducing the enormous consumption of human and material resources in traditional mine monitoring efforts.
