Nowadays,algorithm of unwrapping panoramic cylinder image is easy to produce the block effect,which reduces quality of expanded image greatly.According to the nature of the hyperboloidal mirror and the imaging principle,this paper analyzes the reasons for the defects of the existing algorithm,and gives a mathematical model based on the panoramic image cylinder radial scan unwrapping algorithm.The final algorithm is obtained combined with the unwrapping algorithm of radial scanning and the anisotropic interpolation algorithm.The experiments show that the new algorithm can effectively reduce the block effect and improve the quality of expanded image.
