| 摘 要： | 受众多因素的影响,我们采集到的地球物理数据是离散的,这也限制了获得更多的地下信息。为了便于后期的解释工作,数据的补插网格化就至关重要。数据网格化是将空间上不均匀分布的数据,按一定方法归算成规则网格节点的代表值。这里依据方位加权二次曲面插值算法,利用MFC对话框界面与Surfer的混合编程,读取实测数据信息后,在可视化界面实现网格化处理过程。最后调用Surfer生成区域等值线图,与其内部插值方法绘制的等值线图进行比较。一方面验证了方位加权二次曲面插值算法的可适性,另一方面通过人机交互的方式简洁快速实现了庞大数据的批处理,便于用户使用。

| Abstract: | Affected by many factors,the geophysical data collected is always non-uniformly distributed,which also limits us to get more underground information.In order to facilitate the interpretation of the late work,the data patch interpolation grid process is crucial.Data gridding is spatially reduced uneven distribution of data to regular grid values according to certain methods.Based on the azimuth weighted multi-quadric curving interpolation,this paper makes use of the mixed programming of MFC dialog interface and surfer to read the measured data and realize the gridding process in the visual interface.Finally,the surfer software is used to generate the area contour map and compare it with the contour map drawn by the interpolation method itself.On the one hand,the adaptability of the azimuth weighted multi-quadric curving interpolation algorithm is verified,on the other hand,batch processing of huge data is implemented concisely and quickly through user-computer interaction,which is convenient for users to use. |
