System for realizing VR (virtual reality) scene building design by combining VR and BIM (building information modeling)

Abstract

The invention discloses a system for realizing VR (virtual reality) scene building design by combining VR and BIM (building information modeling). The system comprises a motion capture device, a motion capture interaction module, a VR processing module, a core data processing module, a BIM data processing module, a Unity / UE4 engine and external VR equipment, wherein the motion capture device is used for capturing the user motion and converting the captured motion into motion data and transmitting the motion data to the motion capture interaction module; the motion capture interaction module is used for transmitting the received motion data to the VR processing module and the core data processing module; the core data processing module is used for processing the motion data into the data readable to the external VR equipment and transmitting the readable data to the VR processing module; the VR processing module is used for synthesizing the readable data and a picture; the Unity 3D / UE4 engine is used for dealing with the problems of the picture; and the VR processing module is further used for transmitting the synthesized picture to the external VR equipment so that the user can directly see the user motion captured by the motion capture device from the external VR equipment.

Description

technical field [0001] The invention relates to the technical field of architectural design, in particular to a system that combines virtual reality and BIM to realize virtual reality scene architectural design. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is based on the relevant information data of the construction project as the basis of the model, to establish the building model, throughout the whole life cycle of the building. Therefore, there are different software applications in different stages of construction, such as Revit, which is more used in the design stage. Revit is one of the most widely used software in my country's construction industry BIM system. [0003] All the compositions of BIM store a lot of digital information and parameter data. In addition to the 3D appearance, it also contains geometric information, architectural or engineering information. Therefore, the composition of BIM can be automated ...

AI Technical Summary

Problems solved by technology

[0008] 1. Although the current technology can solve the problem of effect display, it cannot really participate in the architectural design process, and cannot help designers at the beginning of architectural design;

[0009] 2. The current technology still cannot achieve real-time connection and data exchange between VR and BIM-related software;

[0010] 3. At present, it is not possible to edit and modify the architectural design in virtual reality;

[0011] 4. At present, the quality of the models produced by revit is poor, and the display effect after being made into VR is not ideal. When people stay in this virtual reality for a long time, it is easy to cause dizziness and other discomfort;

[0012] 5. The current technology cannot solve the problem of complex composition and modeling of some BIM software such as Revit
