摘要
高分辨遥感技术在军民领域应用广泛,图像配准技术是高分辨遥感图像的预处理技术。实际的机载和星载遥感成像仪,由于自身成像原理和成像仪平台抖动原因,出现了遥感图像亚像素偏移误差。对亚像素图像配准技术进行系统研究,对高精度亚像素配准算法进行研究分析,并对其算法进行仿真、处理,对仿真的结果进行系统分析,通过误差分析提出配准误差修正算法,修正算法对亚像素配准进行了很好的改进,达到遥感图像预处理的目的。
High-resolution remote sensing technology is applied in the field of military and civilian,image registration technique is high-resolution remote sensing image pre-processing technology.The actual airborne and satellite remote sensing imaging device,because of their own imaging principles and imaging platform jitter,is applied remote sensing image sub-pixel offset error.This article appears remote sensing image analysis of image distortion,and mainly analyses sub-pixel image registration techniques.High precision sub-pixel registration algorithm is discussed,and simulation algorithm,processing and analysis of simulation systematic are studied,finally it is the analysis of the results of the matching algorithm to amend errors,correct algorithm is applied in sub-pixel registration technology research,and the purpose of remote sensing image pre-processing.
