Abstract

The invention relates to the information technology application field, in particular to an underground structure three-dimensional digital model construction method which can be used for spatial analysis. The system comprises an underground structure digital model and model overall and computer software and hardware; the method uses the underground structure three-dimensional spatial data model to carry out the three-dimensional digital model construction on various underground structures and basic entities of the underground extension parts of ground structures, thereby reproducing simulated spatial objects; and the model overall design is completed by describing objects, three-dimensional surfaces, bodies, model hierarchy and the relations among the basic layer model, the communicating layer model and the expansion layer model by the model. The method has the advantages that: the underground structure digital model which is constructed by the method can meet the application needs on the underground spatial planning and the management, express the invisible external surfaces and the visible internal surfaces of the underground structures and meet the needs on the underground space retrieval and the analysis calculation, and the method can be widely used without the safety problem.

Description

technical field [0001] The invention relates to an application field of information technology, in particular to a method for constructing a three-dimensional digital model of an underground structure that can be used for spatial analysis. Background technique [0002] The 3D digital model of underground structures is a kind of 3D spatial data model. [0003] The three-dimensional spatial data model is proposed and established for the purpose of reproducing and simulating space objects for spatial analysis and calculation. Since the 1970s and 1980s, the research work on 3D spatial data models has focused on the 3D raster data model represented by the octree, and the Solid Structural Geometry (CSG) model and boundary representation (B -Rep) model, etc. In recent years, the integration and mixing of vector data models and multiple data models, as well as the processing and analysis algorithms based on these models have become research hotspots. Based on the research on 3D s...
