摘要
视差图像的精确配准是图像拼接的关键环节,本文针对校正后待拼接图像垂直方向已近似一致的具体情况,对现有基于小波变换的图像配准算法进行改进,提出了一种基于小波近似图像和垂直细节图像由粗到精的加权全局配准新算法,实验表明该方法提高了配准的准确性、可靠性、实时性,取得了比较好的效果。
The accurate registration of parallax image is the key step of image mosaic.On the point that the images rectificated are almost the same in vertical , we improved the existing image registration method based on wavelet transform , and proposed a coarse-to-fine global registration method using the coarse image weighted with vertical detail image.Experiment results show that the method has improved the accuracy,reliability and real-time property of image registration, and the effect is satisfying.
