Abstract A method is proposed to detect and correct the phase unwrapping error (PUE). Phase edge is defined to help detect points potential with PUEs. Then, phase derivatives of points crossing phase edges are used to inspect whether the phase edges are from surface discontinuity or PUE. This makes it possible to dismiss phases at discontinuous regions during the PUE correction. Hence, the proposed method evidently improves the robustness of PUE correction with little additional time consumption. Experiments confirm that it is capable of correcting PUE with outstanding robustness and efficiency. To the best of our knowledge, it is the first time that phase edge is defined with aid of unwrapped phase, and used for PUE correction.

基于相位边缘检测和分类的相位解缠纠错

摘要 提出了一种检测和校正相位解缠误差(PUE)的方法。定义相位边缘以帮助检测具有 PUE 的潜在点。然后，使用跨越相位边缘的点的相位导数来检查相位边缘是来自表面不连续性还是 PUE。这使得在 PUE 校正期间消除不连续区域的相位成为可能。因此，所提出的方法显着提高了 PUE 校正的鲁棒性，而额外的时间消耗很少。实验证实，它能够以出色的鲁棒性和效率来校正 PUE。据我们所知，这是第一次在解缠相位的帮助下定义相位边缘，并用于 PUE 校正。
