摘要
近年来,随着遥感技术的发展,高光谱、红外、雷达等多源遥感成像手段在精准农业、资源调查、环境监测、军事国防等重要领域发挥着越来越重要的作用。同一场景多源遥感图像观测的地物对象相同,但观测的维度不同,图像的空间、光谱与时间分辨率存在差异,提供的信息既具有冗余性,又具有互补性和合作性。多源遥感图像融合能够综合利用不同来源获取的遥感图像信息,实现更精准、更全面的对地观测,是遥感对地观测领域的核心关键技术。本文从多源遥感图像的数据来源出发,综述了多源遥感图像融合的研究现状与未来发展趋势:首先介绍了国内外现有多源遥感图像的主要来源、图像特性与典型应用;然后,对不同类型多源遥感图像融合的研究现状和挑战性难题进行了归纳和总结;最后,对多源遥感图像融合的未来发展趋势进行了展望。
