Geological modeling method of three-dimensional surface reconstruction based on two-dimensional outlines

摘要

Based on the methods of two-dimensional modeling, we introduced a method of three-dimensional geological modeling using the two-dimensional model's outlines to reconstruct the three-dimensional models. The basic idea is to build a series of two-dimensional cross sections on the basis of geological exploration information, and then extract the geological targets outlines on each cross section, follow by matching and triangulation adjacent outlines in a three-dimensional space, and finally achieve the "Stitching and Sewing" of three-dimensional surface, complete the three-dimensional geological modeling. In this paper, we mainly discuses the matching and connection problems of adjacent outlines in a three-dimensional space.Bases on the cut-suture method, we improve the original contour matching way which simplify the programming process and improving the modeling efficiency.
