提出了一种分区域的复合相位解缠算法。首先根据相位质量图将缠绕相位分成高、低质量区域,并采用质量引导算法求解初始解缠相位。然后采用区域生长法识别出所有的低质量区域,每个低质量区域信息单独存储。最后依次对每个低质量区域进行最小不连续优化,获取最终的解缠相位。对InSAR干涉相位图的解缠试验结果表明,该方法计算效率较最小不连续性算法高一个量级,而计算精度优于质量引导算法,在两者之间取得了很好的平衡。 A sub-region composite phase unwrapping algorithm is proposed. Firstly, the winding phase is divided into high and low quality regions according to the phase quality diagram, and the quality guiding algorithm is used to solve the initial unwrapping phase. Then, all the low quality regions are identified by the region growing method, and each low quality region information is stored separately. Finally, the minimum discontinuity optimization for each low-quality region is performed to obtain the final unwrapped phase. The results of the unwrapping experiments on InSAR interferogram show that the proposed method is one order of magnitude more efficient than the minimum discontinuity algorithm, while the computational accuracy is better than that of the quality-oriented algorithm, which achieves a good balance between the two.
