摘要:
        对ASIFT算法原理进行了深入的分析,并在此基础上提出了基于ASIFT的低空遥感影像拼接的新算法.新算法首先利用ASIFT提取图像对应的特征点,通过最小二乘法计算仿射变换矩阵,最后根据仿射矩阵实现图像的变换与拼接.实验结果表明,由于ASIFT算法具有仿射不变性,相比SIFT算法更加符合低空遥感影像的特点,能很好地解决平移、旋转、仿射变换情况下的图像拼接问题.
Abstract:
This paper analyzed the principle of ASIFT algorithm in depth,and then proposed a low altitude remote sensing mosaic algorithm based on ASIFT.This algorithm first extracted feature points that corresponded with image by ASIFT.Then,it calculated affine matrix by the Least Squares Solution and achieved image transform and mosaic.The experimental results showed ASIFT more tallied with the characteristic of low attitude remote sensing because of its affine invariant,which could better deal with translation,rotation and mosaic under affine transformation circumstances between two images.
