摘要： 鉴于相位相关配准法具有较强的抗光照干扰能力，提出一种扩展的相位相关法，根据相位相关函数峰值的分布特性，利用多峰拟合的方法获得亚像素级的配准结果。实验结果表明，该方法克服了传统相位相关法只能达到整像素配准精度的缺点，并具有较强的鲁棒性和较高的效率。

Abstract: Because phase correlation method has strong anti-interference ability of light, this paper proposes an extended phase correlation registration method. According to the peak distribution characteristics of phase correlation function, the sub-pixel registration is achieved by multi-peak fitting. Experimental results show that the method overcomes the shortage of traditional method that it can only get integer pixel registration, and has strong robustness and high efficiency.

Key words: phase correlation, peak distribution characteristic, sub-pixel registration, multi-peak fitting, super-resolution
