| 摘 要： | 由于观测数据的不足,对不规则散点数据的二维插值在地球物理中应用非常广泛。这里研究并实现了自然邻点二维插值算法,并以一个大地电磁测深反演数据为例,验证了该方法的可行性与效果。实际资料试算与成图结果表明,该方法具有精度高、插值效果好、速度快以及便于模拟地形数据等优点。

| Abstract: | As the observation data is insufficient,two-dimensional interpolation of irregular discrete data is widely used in geophysics.In this paper,we researched and implemented a two-dimensional interpolation of Natural Neighbour algorithm,which will be applied to the MT 2D inversion real-time imaging.Example results show that the method has high accuracy,effective,fast and easy simulation of the data with terrain. |
