The difficult point that impacting the traditional polarization image registration based on Fourier - Mellin transform is calculating rotation angle of the image α and shrinkage variable coefficient τ of polarization image registration .Based on Fourier - Mellin transform method, this paper proposes a improved algorithm that on account of improving resolution in the θ coordinate direction in the Log-polar coordinate system, improve the calculation accuracy of rotation angle of the image α and shrinkage variable coefficient τ .Through the experiment and simulation results show that the improved algorithm than the traditional has higher registration precision.
