摘要
高光谱遥感技术是一种功能非常强大的综合性学科技术,其以数据的实时性、光谱信息的丰富性、成本的高效益性、覆盖范围的广泛性等特征以及高分辨率和图谱合一的优势,在各个领域上得到了广泛的应用。文章介绍了高光谱遥感技术成像的基本原理、国内外高光谱成像仪和高光谱卫星的发展历程,重点描述了高光谱遥感技术在矿山环境监测、水环境监测与评价、土壤含水率监测等方面的应用成果。高光谱遥感技术面临着“维数灾难”、精确度不足、时效性受限、高光谱遥感数据解译困难等问题,未来可通过协同多平台、利用人工智能模型等方式提高精确度,构建典型的光谱库提高模型的普适性。
Hyperspectral remote sensing technology is a highly powerful comprehensive scientific technology that has seen extensive application across various domains,leveraging its strengths in real-time data acquisition,spectral information richness,costeffectiveness,extensive coverage,and the benefits of high resolution and map integration.This manuscript delineates the foundational principles of hyperspectral remote sensing imaging,traces the evolution of hyperspectral imagers and satellites both at home and abroad,and elucidates the outcomes of employing hyperspectral remote sensing in mine environmental monitoring,aquatic ecosystem surveillance,and soil moisture assessment.However,hyperspectral remote sensing still confronts challenges such as“dimensional catastrophe”,suboptimal accuracy,constrained temporal resolution,and the intricacies in interpreting hyperspectral data.Looking forward,enhancements in accuracy can be attained through the integration of multi-platform data and the application of artificial intelligence algorithms,while the development of representative spectral libraries will augment the versatility of the models.
