Auto registration of optical and Synthetic Aperture Radar (SAR) images has always been a difficult problem because of the significant geometric and radiation differences between the images. Firstlythe phase congruency model with radiation invariance is introducedand the direction and scale information of phase consistency are calculated by using indexed map. The directional index map is formed by the direction feature of phase congruencyand the scale index map is formed by the scale feature of phase congruency. Local Phase Congruency Statistics (LPCS)a local descriptor for the imagesis established. FinallyLPCS is used to obtain the points of the same name in optical and SAR imagesand affine transformation model is used to achieve registration. Experimental results show that the proposed method is highly adaptive to the radiation differences between optical and SAR imagesand the registration accuracy is high.
