The methods of image registration and fusion are very important basis of cylindrical panorama creating. There are many relevant algorithms been developed, but many of them usually have limitations on their qualities and efficiency. In this paper, an automatic approach for creating cylindrical panorama is introduced. Compared with many commonly used algorithms, this algorithm is simple and effective. In our method, we adopted an FFT-based phase-correlation algorithm to register images, and we also employed a multi-resolution pyramid algorithm to perform image fusion. By preprocessing the input images using such methods as histogram equalization, we further increased the accuracy and robustness of image registration. Our experiments show that the method is simple, efficient and effective.
