Abstract

The invention discloses a method for processing boundary filtering data in a three-dimensional geological surface model. The method includes the steps of inputting a set of all triangles and a set of all boundary lines, marking all boundary points, selecting any triangle in the set of triangles, determining whether the apex of the triangle is marked, classifying the triangle in a first curved surface set if the apex of the triangle is not marked, otherwise conducting no processing for the triangle, traversing all adjacent triangles of the first curved surface set, classifying the adjacent triangles into the first curved surface set if the apexes of the adjacent triangles are not marked and adjacent edges of the adjacent triangles and the triangle do not belong to the set of all boundary lines, and repeating the previous step until a stable first curved surface set is obtained. The first curved surface set corresponds to an independent spatial section in space, so that the stratum shape can be recovered. The method facilitates quantified research of geological structures.

Description

technical field [0001] This application relates to the field of geographic information systems, in particular to a data processing method in a three-dimensional geological surface model. Background technique [0002] When processing data in the existing 3D geological surface model in the geographic information system, the focus of the research is on the simulation of the geological structure, that is, the rendering and visualization of the geological structure. [0003] In the process of implementing the prior art, the inventors found that at least the following problems existed in the prior art: [0004] The mesh unit in the 3D geological surface model constructed by the geographic information system has poor standardization and low precision, so it is impossible to carry out quantitative research on the geological structure. For example, research on cracks, faults, etc. in geological structures based on a three-dimensional geological surface model. Contents of the inven...
