Abstract

The invention discloses a three-dimensional stratum model dynamic construction method, and relates to a technology of displaying virtual reality on a display screen. The method comprises the following steps: stratum data is subjected to integration; the stratum data is subjected to selection of a definition and a region; data selection is carried out; a modeling construction region scope is determined; the data is determined and improved; grid insertion points are constructed; a data structure is generated; a three-dimensional model is formed. The provided construction method is advantageous in that the method has an important auxiliary effect on urban construction, especially obtaining of underground space information and a construction scheme in further smart city construction. Stereo exploitation of urban space and development and utilization of underground business traffic are promoted, and protection potentials of underground space resources are developed and utilized fully. In addition, in underground mineral reserve exploitation geological research work, three-dimensional modeling can play a protruding role in geological research fully.

Description

technical field [0001] The invention relates to displaying virtual reality technology on a display screen, in particular to a method for dynamically constructing a three-dimensional stratum model by simulating the distribution of strata to realize the construction of a stratum data model and improve the efficiency of urban underground space planning. Background technique [0002] What is a stratigraphic model? The stratigraphic model is a 3D mesh. These grids are based on surface layers, faults and horizons. It determines the structure and geometry of the reservoir. Each node in the grid has a set of properties, such as porosity, permeability, water saturation, etc. A stratigraphic model (pattern) is a simplified expression and comprehensive interpretation of the composition, structure, and spatiotemporal existence of stratigraphic entities. The most common stratigraphic model is a section model in which the composition, structure, and depositional environment of the int...
