THREE-DIMENSIONAL VISUALIZED FORWARD AND INVERSE METHOD OF POTENTIAL FIELD BASED ON OCT-TREE STRUCTURE

本文采用八叉树数据结构提出了一种新的三维可视化人机交互正反演方法 ,应用该方法可以构造复杂的三维位场模型 ,计算出其正演场值 ,通过人机交互界面 ,使模型与数据在整个正反演过程中可视化、形象化。该方法不仅可以进行均匀物性分布正反演 ,也可以进行非均匀物性分布正反演 。

This paper presents a new three-dimensional visualized forward inverse method,which is based on oct-tree data structure.With this method,one can construct a complex geophysical model and compute its forward value.The method can be applied to visualized forward and inverse calculation of both buried homogeneities and buried inhomogeneities,and hence it also has bright future in combined visualized inversion of multiple geophysical variables.
