Due to unreliable phase value and under - sampling in practical situation , especially when a complex shape is measured , phase unwrapping is a difficult step 在实际应用中特别是测量复杂的物体三维面形时，由于噪声阴影等引起的截断位相不可靠及采样不足的问题，位相展开一直是其中的难点。
This paper gives a method applying wavelet transformation to get the blocklines , and construct a binary control mask to supervise the phase unwrapping , and phase interpolation procedure 在这种算法中，利用小波变换寻找截断线，有效地标记出极点和截断线，构造出二元模板指导位相展开。
The unreliable pixels are left to the end of the path when phase unwrapping is proceeded along this path , which avoid error propagating . even in the worse case the error is limited , if three is any 这在很大程度上避免了沿位相不可靠点进行位相展开时引起的误差传播，在最坏的情况下，也能将位相展开的错误限制在局部范围。
With the ability of binary control mask to deal with under - sampling areas successfully , and with the ability of modulation ordering resulting in an optimized path , the new algorithm can be applied to complex phase unwrapping 新算法对于采样不足的区域有着很好的处理效果，并且保留了调制度函数本身处理局部阴影等截断位相不可靠区域的能力。
