摘    要:基于相位相关的图像配准方法以其运算量小、抗干扰性强等优点得到广泛关注,但它只能解决具有平移运动的图像配准问题,为此,文章提出一种改进的相位相关配准方法,分析了其配准原理,给出流程图,并将其应用于存在缩放、旋转和平移变换的SAR图像配准中。仿真结果表明,该算法能够较为准确地估计出待配准图像相对于基准图像的平移参数、缩放尺度和旋转角度。

关 键 词:图像配准  相位相关配准  平移变换  尺度变换

Abstract:Phase correlation-based image registration method is widely concerned for its small computation amount, strong anti-interference property. However, it can only solve the image registration problem with translational motion. Therefore, a modified phase correlation registration method was proposed in the paper. The principle of registration was ana- lyzed, the flow chart was given, and the method was applied to the SAR image registration problems with scaling, rotation and translation transformation. Simulation results show that the method can accurately estimate the translation parameters, zoom scale and rotation angle of registrating image relative to the reference image.
Keywords:image registration  phase correlation registration  translation transform  scale transform
