Theoretical cylindrical unwrapping algorithm for omni-directional image costs a larger system resource,and is not suitable for embedded systems with limited resources.So it is significant to improve and design the algorithm based on embedded systems.In this paper,according to the theory of cylindrical unwrapping algorithm,a fast cylindrical unwrapping algorithm based on the FPGA is designed.The feasibility of the algorithm is verified with the software Matlab,and then hardware module is designed with hardware description languages.After simulation through the ModelSim,the improved algorithm for omni-directional image is achieved on the FPGA hardware platform.
