摘要
介绍一种最小二乘解相位包络的方法 ,该法的优点在于把图像作为一个整体处理 ,图像上每一个像素点的值由方程唯一确定 ,而且解得的相位图与原包裹的相位图偏差平方加权最小 ,具有局部解相法所不具有的优点。实验证明 ,它能够处理局部处理方法难以解决的相位图 。
A least square method for phase unwrapping is proposed Its theory and processing procedures are described in detail As it deals with every pixel as a whole, unlike traditional local method, it is more flexible and can be applied to more complicated wrapped phase map At last some examples show that this least square unwrapping algorithm is effective and robust
