Abstract
3D geological modeling data can only be measured rarely or indirectly, as it is necessary to interpolate the sparse and uneven geological data in the study area. Given the problems in the interpolation of data from different sources, we have introduced stratum interpolation and visualization technology based on the moving least squares (MLS) method and Poisson surface reconstruction method. The MLS method can not only obtain a smooth stratum surface by adjusting the relevant parameters of its interpolation, but it can also ensure the similarity of the stratum in space and the difference when far part. At the same time, it combines the Poisson reconstruction method and improves it, so that it can reconstruct the open surface by using a virtual outer frame from the original closed figure reconstruction theory. This paper takes the exploration line profile and geological boreholes in Xiushan County, Chongqing as an example, and visualizes them by fusion and the interpolation of data from different sources. The resulting stratum surface is smooth, continuous, accurate, and highly portable.
