The path for phase unwrapping is determined by the intensity modulation in the pixels on the boundary of the phase unwrapped areas.

在位相展开区域的边界上，位相展开的路径由像素的强度调制决定。

Several typical phase unwrapping algorithms are introduced, the effectiveness of the branch cut algorithm and the quality-guided path following algorithm is validated by experiments.

介绍了多种典型的相位去包裹算法，通过实验验证了分割线法和质量导向图法的有效性。

Many factors, such as noise, speckles and low modulation in wrapped phase make the unwrapping procedure complicated and path-dependent.

实际干涉计量中各种干扰因素的存在，使得包裹相位图中可能存在噪声、低调制点或散斑等误差点。
