A phase unwrapping method based on simulated annealing is proposed. In this method, the local phase approximation of the main phase phase diagram is used, and the optimization plane parameters are obtained by the simulated annealing algorithm to obtain the true phase diagram of removing noise and 2π phase transition. Computer simulation and experimental results show that this method can effectively remove the noise in the phase diagram, realize the phase unwrapping of the phase diagram with noises, and reliably reconstruct the surface topography of the measured object. The principle and experimental results of this method are introduced in detail
