Embodiment Construction

[0093] Such as figure 1 As shown, the present invention provides a method for integrating glTF-based BIM data and GIS data, comprising the following steps:

[0094] S1. Extract the project information, site information, building information, floor information, room information, opening information and building component attribute information in the IFC model file, generate an attribute information model when extracting the IFC model file, and generate a JSON based on the attribute information model Attribute information file in format;

[0095] S2. Preprocessing the component information of the IFC model file, extracting the geometric information of the component in the IFC model file, generating a glTF format architectural model through geometric transformation, and generating a glTF architectural model file matching the attribute information file; the preprocessing Add "@" and "component ID" after the name of the component in the IFC model file;

[0096] S3, matching the a...

Abstract

The invention discloses a method for integrating glTF-based BIM data and GIS data, comprising the following steps: S1, extracting BIM attribute information, generating an attribute information file in JSON format; S2, extracting and converting BIM geometric information, generating an The glTF architectural model file that matches the attribute information file; S3, BIM attribute information and geometric information match to form a glTF architectural model with attribute information; S4, BIM and GIS data integration, import the glTF architectural model into the Cesium platform, and glTF architectural The model is placed in the world geographic coordinate system, so that all the building information of the glTF building model is associated with the geographic space and visualized in GIS; this method can overcome the information loss, data overload and poor visualization in the traditional integration process problems, to realize the effective integration of BIM data and GIS data.

Description

technical field [0001] The invention relates to the technical field of building intelligence, in particular to a method for integrating glTF-based BIM data and GIS data. Background technique [0002] In the construction industry, building information modeling and management (BIM) is widely recognized as a new tool that can improve production efficiency and delivery quality. BIM is mainly aimed at the building itself, transforming the architectural engineering drawings from the traditional two-dimensional model into a visualized three-dimensional model, and including all the building information in the building life cycle. It facilitates the extraction of project information by all parties such as design, construction, operation and maintenance, and greatly improves the accuracy and production efficiency of construction projects. In order to ensure that information data can be transmitted and exchanged completely, consistently and correctly within the construction industry, ...
