摘　　要：在多光谱遥感水深反演中,数据匹配是建立统计相关模型的基础。采用两种多光谱遥感影像数据,研究了像元找水深点的顺序匹配法和水深点找像元的顺序匹配、二分匹配和像元坐标法等数据匹配方法,并开展相应的实验验证。结果表明,4种匹配方法一定程度上能满足当前多光谱遥感水深反演的数据匹配需要,其中,水深点找像元的像元坐标法耗时最短,匹配效率最高。Data Matching is the basis of statistic correlation model in multispectral remote sensing bathymetry.For this reason,this article uses two kinds of multispectral remote sensing images and studies sequence matching method of Pixels to Soundings and sequence matching,binary matching and pixel coordinates methods of studies to Pixels.Then a verification experiment is carried out.The result shows these four methods can meet the requirements of current data matching in multispectral remote sensing bathymetry to some extent and pixel coordinates method of soundings to pixels takes the shortest time and thus get the best matching efficiency.
