Building 3D model construction method and device

Abstract

The invention provides a building 3D model construction method and device. The construction method comprises the following steps that: the physical data of a building to be constructed are obtained; a corresponding data model is generated according to the physical data of the building to be constructed; the data model is divided into a plurality of building components, and the data of the building components are obtained; whether the data of the building components conform to preset 3D model construction standards is judged, corresponding operation is carried out according to judgment results; the data of the building components are modified, so that the modified data can conform to the construction standards; and the building components and the corresponding data thereof are integrated, so that a 3D model corresponding to the building to be constructed can be constructed, and corresponding 3D model data are obtained. With the construction method and device adopted, the unified 3D model building standards are provided, so that the 3D model which can reflect the specific construction plans of the building to be constructed more authentically can be constructed, and optimal construction plans of the building to be constructed can be provided.

Description

technical field [0001] The invention relates to the technical field of engineering modeling, in particular to a method and device for building a 3D model. Background technique [0002] With the gradual development of BIM (Building Information Modeling, Building Information Modeling) simulation technology, BIM simulation technology has been widely used in construction projects because of its advantages of visualization, coordination, simulation, optimization and drawing. Architectural engineers are gradually liberated from traditional drawing methods. By using BIM simulation technology to simulate projects, the errors that engineers make when drawing engineering construction drawings are greatly reduced, and the engineering construction plans proposed by engineers can be optimized to improve the quality of engineers. work efficiency. [0003] But for now, there are still many technical problems to be solved in BIM simulation technology. Among them, the inconsistency of mecha...

Problems solved by technology

[0003] But for now, there are still many technical problems to be solved in BIM simulation technology. Among them, the inconsistency of mechanical component information models used by various construction companies in BIM simulation technology is a very serious problem.

In reality, each construction company has a different set of information model design and construction standards for the same mechanical component in BIM. When assembling the mechanical component information models designed by different construction companies, component errors are prone to occur. It is impossible to truly carry out BIM simulation on the building to be constructed corresponding to the construction project, and obtain an optimized construction plan, which seriously affects the normal construction of the construction project, so that the corresponding building of the construction project cannot achieve the corresponding preset effect
