Navigation with catadioptric omni-directional vision is a new technology in the domain of auto-mobile robot,but the image getting from catadioptric sensor is distorted and not suitable for target locating or tracking,so cylindrical calculation should be employed on the original omni-directional image.In this paper,one kind of method to find the center coordinates of the omni-directional image is presented,which is the base for cylindrical calculation,and quadratic interpolation method is used in the process of cylindrical calculation.According to the experiments,an improved cylindrical calculated image is more suitable for human-computer interaction.
