摘要 研究一种快速、准确的适用于大角度旋转的多光谱图像和全色图像自适应配准方法.该算法首先基于小波变换提取图像的角点作为特征点,然后提出利用基于区域带旋转角度估算的相似度最大和三角形相似的方法确定最佳的配准参数,最后采用迭代算法优化配准参数.实验结果表明:该方法可以准确、自动地获得不同的多光谱图像和全色图像之间的配准参数. A quick,accurate and adaptive image registration method applied to large rotation angle for multi-spectral image and panchromatic image is presented.It extracts the corner points of two images based on wavelet transformation firstly.Then the maximum of correlation coefficient with the estimation of rotation angle based on region and triangle similarity is developed.Finally,the iterative algorithm is used to get the optimal registration parameters.Experiment results show that the method can register multi-sp...
