Th is paper introduces the theoretical unw rapp ing algorithm for omn idirectional mi age, and pro poses an approach to smi plify this algorithm, and optmi izes the fast unw rapping algorithm. The paper also compares these tw o algorithms. According to the expermi ents the fast unw rapp ing algorithm meets the demand of the realtmi e system.
