A Geological 3D Modeling Method Based on Radial Basis Implicit Surfaces
In view of the drawbacks of the current process for generating geological 3D models based on drilling data, which are cum-bersome, complex in algorithms, and have large intermediate data, this paper describes the geological surfaces using drilling points and radial basis implicit function models. It visualizes the geological surfaces by extracting isosurfaces of the surface function models with polygonal scalar fields. The border of the extracted surface is determined by extracting the turning point data of the border based on the length of the grid. The vertical profile is drawn based on the turning points of the borders of the adjacent upper and lower geo-logical surfaces. Finally, the vertical profile is merged with the adjacent upper and lower geological surfaces to generate the 3D geolog-ical model. In the experiment, drilling data from the High-tech Zone of Zhengzhou city is used as the data source, and a complete and fast 3D geological model of the study area is generated.
