摘要

川藏铁路沿线山高路险,很多区域人车难以到达,采用常规的勘察手段实施难度极大。高光谱遥感数据能有效大面积地对岩石进行分类,其理论依据是岩石的反射光谱曲线差异性。本文选择川藏铁路拉萨段,通过野外岩石标本采集,应用美国ASD光谱仪开展了室内光谱测试,并基于ENVI软件对采集光谱进行了预处理,最后分析了研究区不同岩石类型光谱差异性,为后期高光谱遥感数据岩石分类识别提供了理论依据。
The mountain is very high and road is very dangerous in Sichuan-Tibet along the railway,many areas difficult to reach,we are extremely hard using conventional means of surveying practice.Hyperspectral remote sensing data can effectively classify large area of rock,its theory is based on the spectral reflectance curve of the rock.This paper takes the Sichuan-Tibet railway Lhasa section as example,carried out the field rock sample collection,tested the field rock sample spectrum using ASD spectrometer indoor and preprocessed the collected spectra.Finally,this paper analyzes the spectral differences of different rock types in the study area,which provides a theoretical basis for the post-rock hyperspectral remote sensing data classification.
