Embodiment Construction

[0040] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0041] Such as figure 1 As shown, a large-scale building information model and three-dimensional digital city integration method is characterized in that it includes the following steps:

[0042] Step 1: Build a building information model.

[0043] Step 2, extracting and storing building component information.

[0044] Step 3: Integrate the building component information data with the 3D digital city.

[0045] The extraction and storage of building component information is carried out in the following steps:

[0046] A1. Extract building component information of walls, slabs, columns, stairs, doors, windows, railings and roofs.

[0047] A2. Establish the building component information model semantics, and store the acquired building component information in the building information database; the building component information model semantics include: the ...

Abstract

The invention discloses a large-scale building information model and a three-dimensional digital city integration method, and belongs to the field of spatial information technology. Interactive construction is carried out on the building information model on the basis of construction drawings, then the building information model is converted into a building component information model through spatial and semantic information mapping, a building component information base is established, and integrated application of building component information is carried out in three-dimensional digital city scenes. A large-scale indoor spatial structure data source is provided for a three-dimensional digital city, and the utilization rate of data is improved; internal spatial structures of buildings and external environments are displayed integrally. The building component information model with consistent semantic and spatial information is established, various sensors in the buildings can be integrated, and useful supports are provided for smart city application.

Description

technical field [0001] The invention belongs to the technical field of spatial information, in particular to a large-scale building information model and a three-dimensional digital city integration method. Background technique [0002] Building Information Modeling (Building Information System, BIM) was proposed by Autodesk in 2002 and is a building information tool widely used in the construction field. Based on 3D digital technology, the building information model inherits the engineering data model of various related information of the construction project, and is the digital expression of the entity and functional characteristics of the project facilities. A complete building information model, which can associate data, processes and resources in different stages of the construction project life cycle (design, construction, operation, demolition), is a complete description of engineering objects and can be commonly used by all participants in construction projects.
