基于curvelet域的位场多源数据融合方法
Keywords: 位场勘探,数据融合,curvelet域,加权算子,中扬子地区
Abstract:
?如何将大面积低精度数据与局部高精度数据进行融合,统一编制图件,是地球物理综合研究面临的重要问题。位场数据融合主要对低、高精度数据重叠区进行融合,为了提高融合效果,保持重叠区高精度信息,本文提出了基于curvelet域的结合区域梯度的边界衰减方向加权融合算法。该法利用尺度和梯度调节衰减函数对不同方向的curvelet系数进行加权处理。理论分析及中国南方中扬子地区的区域航磁数据融合实例表明,本文算法可以在保持局部信息的前提下,能够以较小的重叠区域,实现不同精度数据间的融合,重叠区数据精度高,同时避免了高频震荡、异常扭曲等边界效应。
