BIM (Building Information Modeling)-based VR (Virtual Reality) virtual feeling system

Abstract

BIM-based VR virtual experience system. A BIM-based VR virtual experience method, using BIM technology to generate a BIM architectural model in the computer that is consistent with the planning and design; on the basis of the BIM architectural model, establish a building component characteristic module; transmit the BIM architectural model model through the wireless transmission module To the display helmet worn by the observer; use the positioning system to obtain the observation information of the observer, and at the same time transmit the observation information of the user back to the BIM building model in the computer, and the BIM building model receives the observation information of the observer and updates the building model data ; The observer uses the selection handle to output the conversion information of the selected component characteristic module, and transmits the image or parameter information with the selected component characteristic to the user. The advantage of the present invention is: the material and component material library is established on the basis of the BIM model, and the user can interact with the virtual reality based on the handle while viewing the scene personally, and replace the relevant materials and components for viewing.

Description

technical field [0001] The invention relates to a BIM-based VR virtual feeling system. Background technique [0002] BIM (Building Information Modeling), generally understood as a building information model, is a construction cycle information management technology with five characteristics of simulation, visualization, coordination, optimization and drawing. In short, BIM is a new method of architectural design, construction, management, and supervision. It is based on three-dimensional digital information technology and includes data information in all stages of architectural planning, design, construction, and operation. Staff can make effective and correct decisions based on the model and the data provided by the model at any stage in any life cycle of the building. [0003] VR (Virtual Reality, or virtual reality, referred to as VR), comprehensively utilizes computer graphics systems and various interface devices such as reality and control, to provide immersive techno...
