Abstract提出了一种相位跳变区域的确定方法,在此基础上提出一种基于相位跳变区划分的相位展开方法。计算机模拟和实验结果均证明:此方法对噪声有很强的抗干扰能力,能有效地实现带噪声的主值相位图的相位展开。

Other AbstractPhase unwrapping is widely applied in a variety of fields including optical and microwave interferometry, adaptive optics, synthetic-aperture-radar and image processing. A phase unwrapping method based on segmenting regions containing phase jumps is proposed. The more the neighbors around a pixel have phase values nearpiand -pi, and the smaller the number difference between the neighbors nearpiand -piis, the more possibly the pixel locates near a phase-jump line. The pixels with high possibility form the phase-jump regions, which can be eliminated by compensating the pixels with a multiply of ZTC to minimize the phase difference between them and their neighbors. After removing phase jumps, ordinary filtering operations can be utilized to postprocess the noisy unwrapped phase map. Computer simulation and experimental results make it clear that the method can effectively remove noise in phase map and unwrap the wrapped phase.
