Abstract

The invention relates to the field of three-dimensional geological modeling, and in particular to a mesh generation and visualization method and system based on a three-dimensional urban geological model, and the method is characterized in that the method comprises the steps: S1, mesh generation: calculating an outer bounding box of a structural model, carrying out the regular mesh generation of the outer bounding box, and generating a regular mesh regular hexahedron attribute model; S2, data storage: storing a central point coordinate value and an attribute value of each subdivided regular hexahedron unit grid in the bounding box; S3, visualization: extracting an outer contour frame of the structure model, pasting a texture picture to the contour frame model, and representing the same geologic model by adopting a plurality of grid units in combination with a multi-detail-level LOD technology; S4, efficiently positioning the grid information; and S5, grid attribute query: dynamically generating a grid according to the returned result set and submitting the grid to the user, wherein the grid attribute query comprises multiple query modes. According to the method, the storage mode ofthe three-dimensional urban geological model is optimized, and visualization of large data volume is supported.

Description

technical field [0001] The invention relates to the field of three-dimensional geological modeling, in particular to a grid division and visualization method and system based on a three-dimensional urban geological model. Background technique [0002] 3D Geology Modeling (3D Geology Modeling) is a discipline based on data / information analysis and synthesis. It combines geological, well logging, geophysical data and various interpretation results or conceptual models to generate a 3D quantitative random model. Technology, in a virtual 3D environment, combines tools such as spatial information management, geological interpretation, spatial analysis and prediction, geostatistics, entity content analysis, and visualization, and uses them for geological analysis. [0003] With the development of my country's economic construction and the continuous improvement of urbanization level, urban geology has been damaged to varying degrees. On the basis of 3D visualization, using the ge...
