Abstract

The invention discloses a BIM-based freeway model VR (Virtual Reality) display method. The method comprises the steps of 1, installing a Unity3D platform in a computer, importing a SteamVR Plugin into the Unity3D platform, and then setting a freeway BIM in the Unity3D platform; 2, enabling a display helmet equipped with a displacement sensor, a left handle simulator and a right handle simulator to establish a wireless communication connection with the computer through a wireless receiving and transmitting module; and 3, setting a selection key and a trigger key in the left handle simulator and the right handle simulator respectively, and enabling the selection key and the trigger key to perform man-machine interaction with the freeway BIM through a secondary development script. The method has the advantages that an observer can watch attribute information of the freeway BIM immersively without being familiar with software, and human-VR interaction is realized.

Description

technical field [0001] The invention relates to construction cycle information management technology, in particular to a BIM-based expressway model VR display method. Background technique [0002] BIM (Building Information Modeling, or BIM for short), is another important computer application technology following the emergence of CAD technology in the engineering construction industry. It is a construction cycle information management technology with simulation, visualization and coordination Five characteristics of flexibility, optimization and map output. Based on three-dimensional digital information technology, BIM is a brand-new method of design, construction, management, and supervision. BIM includes data information in all stages of planning, design, construction, and operation. At any stage in any life cycle of a building, staff can make effective and correct decisions based on the model and the data provided by the model. VR (Virtual Reality, or virtual reality, r...
