Phase unwrapping in large depth-of-field scenes

This paper mainly introduces an accurate and fast phase unwrapping method in large depth-of-field scenes. Firstly, we introduce two mainstream algorithms for solving absolute phase by wrapped phase: spatial phase unwrapping algorithm and temporal phase unwrapping algorithm, and analyze the advantages and disadvantages of the two phase unwrapping algorithms, then analyze the problems of phase unwrapping in large depth-of-field scenes in these two mainstream methods, then introduce the improved method in large depth-of-field scenes, and prove the effectiveness of this method by experimental comparison. Then, we introduce the improved method in large depth-of-field scenes, and demonstrate the effectiveness of this method through experimental comparison, which can improve the speed of measurement and can meet the requirements of the fast measurement in large depth-of-field scenes.
