Abstract

The invention discloses a local quick updating method of a mixed voxel geological body model. Firstly, the method builds an overall mixed voxel geological body model, which is an IHG-TIN model (Irregular Hexahedron Grid and Triangle Irregular Network). When the mixed voxel geological body model needs to be updated because of a local new bore hole or other local exploration data, the method only needs to build a local mixed voxel geological body model on the same local scale. A new voxel is used to replace a voxel at the same position of the original model locally, then a new layer model is extracted from the updated mixed voxel geological body model, and the topological relation and geological properties of the layer model are updated, so that quick local dynamic updating is achieved. The original model does not need to be rebuilt from the beginning, and thus the dynamic updating efficiency and model precision of geological bodies can be improved.

Description

technical field [0001] The present application relates to the field of geological exploration, in particular to a local fast updating method of a mixed voxel geological body model. Background technique [0002] The 3D geological modeling in foreign countries started in the 1970s. [0003] Among them, the more influential ones are: [0004] Professor J.L.Mallet (1989) of the University of Nancy in France proposed the "discrete smooth interpolation method" technology, and developed a 3D geological modeling software based on this technology. The modeling idea is essentially level modeling. [0005] Subsequently, DeKemp's (1999) Bezier-NURBS (Bessel-Non-Uniform Rational B-spline) hybrid surface was used to fit the three-dimensional structural surface, and Courrioux et al. (2001) proposed the Voronoi (Voronoi) diagram to construct geological objects, etc. Both belong to the homogeneous layer modeling of the same layer, and cannot express the fine attributes of each point hetero...
