Layered virtual grid obtaining method, device and system

Abstract

The embodiment of the invention discloses a layered virtual grid obtaining method, device and system. The method comprises the steps of: creating a base rectangular net; creating the rectangular net of each layer on the base rectangular net according to the number of times of layering, wherein the rectangular net of each layer is a result after crossing splitting of the rectangular net of the previous layer; creating a mixed net on a rectangular net of an nth layer, wherein n is the maximum value of the number of times of layering; traversing the rectangular net of each layer to obtain a mixednet comprised in the rectangular net of the current layer, and performing classification of the mixed net to create a virtual of each layer according to a classification result.

Description

technical field [0001] The present application relates to the technical field of virtual grids, in particular to a method, device and system for obtaining hierarchical virtual grids. Background technique [0002] Contour map is an important representation method in geological research work, which generates smooth geological structure map by interpolating some discrete points. There are many interpolation methods for contour maps, and the more classic methods include inverse distance weighting, spline interpolation, kriging, radial basis function, minimum curvature and so on. When the interpolation constraints are only discrete points, these classical methods are relatively simple and practical, but when complex constraints such as faults, fault distances, facies control, and trend surfaces need to be added, these methods will be more difficult to implement, and by J.L. The discrete smooth interpolation (DSI) method proposed by Professor Mallet can overcome this difficulty, ...

AI Technical Summary

Problems solved by technology

For rectangular grids, because of its regularity, it is easy to implement hierarchical division, but the degree of conformity to complex constraints, such as fault lines, is relatively poor

For triangular meshes, although the degree of conformity to complex constraints is very good, it is very difficult for hierarchical division because of its arbitrariness and irregularity.
