摘要
提出了一种基于仿射变换模型的图像自动对准方法.该方法采用基于边缘特征匹配和一致性判断技术,既实现了同名匹配点的自动选取,又提高了同名匹配点的可靠性.同时运用最小二乘法的迭代修正得到仿射变换的最优估计.以可见光与可见光、可见光与红外图像间的自动对准为例,验证了该方法在多模态图像间自动对准的有效性.
A new image registration approach based a affine transformation model is proposed. The combined technique of edge-based feature, consistency checking and least square estimation is proposed to solve the problem. The experiment results show that this approach is effective in multisensor image automated registration.
