摘要
本文根据位相的分布特点提出了一种简单有效的相邻区域位相去包裹免疫算法 ,可以对含有噪声和无效数据区的包裹位相图进行正确去包裹 ,不需要先识别误差点 ,去包裹过程与路径无关 ,算法简单 ,可以有效地解决去包裹误差扩散问题 ,消除“拉线” ,现象。同时 。
According to the characteristic of the phase distribution,a newly developed noise-immune algorithm for phase unwrapping based on neighboring points,which is simple and concise,is presented.The proposed algorithm can directly process wrapped phase including jumping inconsistent pixels and invalid data area independently of the scanning path,avoiding the propagation of the error.Also,the simulation results prove its effectiveness and robustness.
