Background
The BIM is a new tool for architecture, engineering and civil engineering, and its core is to provide a complete building engineering information base consistent with the actual situation for the model by establishing a virtual building engineering three-dimensional model and using digital technology. The information base not only contains geometrical information, professional attributes and state information describing building components, but also contains state information of non-component objects (such as space and motion behaviors). By means of the three-dimensional model containing the construction engineering information, the information integration degree of the construction engineering is greatly improved, and therefore a platform for engineering information exchange and sharing is provided for related interest parties of the construction engineering project.
VR is a virtual reality technology that encompasses a computer, electronic information, and simulation technologies, and is basically implemented in such a way that the computer simulates a virtual environment to give people a sense of environmental immersion. With the continuous development of social productivity and scientific technology, VR technology is increasingly in great demand in various industries. The VR technology has made great progress and gradually becomes a new virtual reality technology in the scientific and technical field, that is, the virtual reality technology utilizes data in real life and combines electronic signals generated by computer technology with various output devices to convert the electronic signals into phenomena which can be felt by people, and the phenomena can be true and real objects in reality and can also be substances which can not be seen by the naked eyes and are expressed by a three-dimensional model. Because these phenomena are not directly visible, but are simulated by computer technology, they are called virtual reality;
the Chinese patent with the current publication number of CN109583085A discloses a building construction quality control method based on BIM and VR technology, which comprises the steps of creating a deepened graph of sample plate nodes of each professional virtual process; creating a visual process template based on the BIM technology; identifying detailed components, materials, quality acceptance standard diagrams and construction process flow diagrams in a virtual process sample plate based on a BIM technology, and rendering and creating a 4K-level process node diagram; creating a virtual process template three-dimensional panorama by using VR technology; compiling a detail node introduction description audio file in the virtual process template; uploading the BIM + VR virtual process template drawing and the audio file to a VR-level cloud management platform; and adding a virtual process template construction process introduction audio file in the VR-level cloud management platform.
Although the building construction quality control method based on the BIM and VR technology realizes the application of the BIM technology and the VR technology in a virtual process sample plate, realizes the management concept of green construction with land saving, material saving and energy saving, and has high economic benefit and social benefit, the information of a client and a construction party is asymmetric due to the inexperience of the client to the building industry, and the construction process performed in the virtual sample plate has certain packing property and exemplarity, and the construction quality of a house can not be actually checked.
