| Abstract: | A rapid two-dimensional linear interpolation algorithm based on the Delaunay triangulation for magnetotelluric(MT) inversion process is researched and implemented,and is applied to the data griding in real-time imaging of MT inversion.The result of using the algorithm in true case shows that the algorithm is stable,fast with good interpolation effect,and is easy for simulating topographical data.It can meet the needs of real-time imaging in MT inversion. |
