摘要
提出一种基于相位相关的图像匹配方法。针对仅有位移变换的图像,给出基于相位相关的模板匹配方法,并进行了改进,然后利用人工平移的方式进行实验验证。结合Fourier-Mellin变换理论,给出解决旋转问题的图像匹配方法,并利用人工旋转的方式进行了实验验证。实验结果表明,本方法在精度和速度上都能取得比较满意的效果。
A method of image matching based on phase correlation is introduced in this paper. Aiming at the only shifted images, a method of template matching based on phase correlation is given and improved as a new approach, and these methods are validated by experiment of shifted registration. A approach of image matching to resolve the rotated problem is presented using Fourier-Mellin transform theory and validated by experiment of rotated image registration. The experimental results show that the method is satisfied with speed and accuracy.
