二维元胞自动机相位解缠算法的改进

IMPROVEMENT OF PHASE UNWRAPPING METHOD FOR TWO-DIMENSIONAL CELLULAR AUTOMATA

提出一种改进的二维元胞自动机相位解缠算法。通过将原有元胞自动机相位解缠算法中的4邻域迭代规则改进为最近邻域规则,以干涉图的边缘作为始点进行迭代,逐一减少干涉条纹的数目,达到相位解缠的目的。用模拟和真实的干涉图进行实验,结果表明,该算法减少了原有元胞自动机相位解缠算法的迭代次数,降低了计算机内存的占用率,提高了相位解缠的精度。

An improved phase unwrapping method for cellular automata is proposed.It revises the four neighborhood of the original method to the nearest neighborhood,begins from the boundary of the interferogram to iterate,eliminates the phase fringes one by one to achieve the purpose of phase unwrapping.The experiments by using the simulated and real interferograms are made.The result shows that this method can decrease the original iterative times,reduce the occupancy rate of the memory and improve the accuracy of the phase unwrapping.
