摘要
提出了一种新的相位去包裹算法,主要针对那些条纹数少,条纹质量相对较好,仅仅是由于少数低调制度点、散斑点、噪声或灰尘引起的去包裹失败的情形。该算法基于一维FFT(快速傅里叶变换),简单且易于实现。
Abstract
A new phase unwrapping algorithm is presented. It is mainly used in the cases in which there are a few fringes and the quality of the fringes is relatively good, however, a failure of unwrapping is encountered only due to low modulation points and speckle points noises, or due to dusts. The algorithm is based on one dimension FFT. It is simple and easy to realize.
