Problems solved by technology

[0007] The current model establishment based on BIM technology and the technology of simulating real information are very mature, but the display method of BIM technology is still based on a single flat reality terminal. The feeling of being on the scene does not provide a good sensory effect for the observer

Abstract

The invention provides a BIM based virtual reality displaying method and system. The BIM based virtual reality displaying method comprises the steps of 1 generating a BIM building model; 2 transmitting the BIM building model to a display helmet worn by an observer; 3 utilizing a sensor installed on the display helmet to obtain observation information of a user and transmitting the observation information of the user to the BIM building model and enabling the BIM building model to receive the observation information of the user; 4 updating BIM building model data according to the observation information of the observer and repeating the step 2 to continue to execute the steps. By means of the BIM based virtual reality displaying method, required building information can be only locally displayed at the viewing angle of the observer, the burden of an image processing device is reduced, the field requirement is low, and the method is not limited by environment and enables the observer to have strong immersion and to be personally on the scene.

Description

technical field [0001] The invention relates to the field of building information models, in particular to a BIM-based virtual reality display method and system. Background technique [0002] BIM is the abbreviation of Building Information Modeling, which is usually translated into building information model in China. It is an information management technology for the whole life cycle of a building, which has five characteristics of visualization, coordination, simulation, optimization and drawing. BIM is a brand-new method of architectural design, construction, and management. Based on three-dimensional digital information technology, all data in planning, design, construction, and operation stages are included in the 3D model, allowing the entire life cycle of the building to When using the model, workers at any stage in the process can make effective and correct decisions based on accurate and complete data. [0003] Virtual reality (Virtual Reality, referred to as VR) ...
