| 摘 要： | 进行高精度磁测会受到很多地表干扰,造成采集数据畸变,因此必须在各种处理方法运用之前剔除掉。利用Matlab GUI的可视化、绘图及鼠标事件功能,实现了交互式地剔除地表磁测数据中畸变点的方法。实践表明,这种方法不仅提高了畸变点的剔除效率,还可以最大程度地保留正常数据点的信息。

| Abstract: | he high precision magnetic survey is liable to suffering many kinds of surface interference which cause data distortion;therefore,the distortion points must be rejected before processing.For the purpose of implementing interactive rejection of distortion points in magnetic data,the authors employed the functions of Matlab GUI,which are characterized by visualization,drawing and mouse case.In practical application,this method enhances the efficiency of rejecting distortion points in magnetic data and preserves most information of normal data points. |
