摘    要:提出了一种基于Harris特征点提取和小波金字塔的遥感图像快速匹配技术.在对多分辨率遥感图像进行完预处理的基础上,先利用Harris算子提取待匹配图像的特征点,然后利用小波金字塔完成匹配.通过杭州地区TM和SPOT遥感影像的配准实验,表明该算法减少了人工干预,提高了运算速度,又保持了匹配精度.

关 键 词:图像匹配  Harris算子  小波金字塔

Abstract:A matching method for remote sensing images based on Harris operator and wavelet pyramid is proposed. After the multi-resolution remote sensing images have been pre-processed, Harris operator is employed as a corner detector for extracting feature points. Subsequently, image-pyramids are constructed by wavelet transform, and then performed matching to images is performed. The experiment in matching Hangzhou TM and SPOT images demonstrates an exactness and speediness result.
Keywords:image match  Harris operator  wavelet pyramid
