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。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.
