摘要

摘要

En 中文
近年来无人机高光谱技术的进步,促使地质学界的研究增多,例如资源勘探和矿物制图。在超镁铁质岩石中发现暗色矿物组合,可能对使用无人机高光谱影像进行光谱分析构成挑战。本研究以Serpentine Mine为试验场地,测试基于无人机的光谱技术用于超镁铁质岩石中蛇纹石化的制图。高光谱数据采用覆盖400-2,500 nm波长范围的490个光谱通道的高光谱相机采集。最小波长映射技术表明,无人机高光谱系统可有效用于识别与2,325 nm处吸收特征相关的蛇纹石化。野外观察和岩石样本的光谱测量结果证实了高光谱成像在蛇纹石化检测中的性能。然而,云层覆盖导致日照减弱,削弱了蛇纹石化的吸收特征。
