| 中文摘要 | this paper describes a path-following phase unwrapping algorithm and a phase unwrapping algorithm based on discrete cosine transform (dct) which accelerates the computation and suppresses the propagation of noise. through analysis of fringe pattern with serious noises simulated in mathematic model, we make a contrast between path-following algorithm and dct algorithm. the advantages and disadvantages or analytical fringe pattern are also given through comparison of two algorithms. three-dimensional experimental results have been given to prove the validity of these algorithms. despite dct phase unwrapping technique robustness and speed in some cases, it cannot be unwrapping inconsistencies phase. the path-following algorithm can be used in automation analysis of fringe patterns with little influence of noise.
