The invention discloses a building updating design method based on digital integrated modeling and a
virtual reality interaction platform, which forms a
point cloud model by means of a digital
information acquisition technology for indoor and outdoor scanning of an old building, and assists professional
modeling software in rapid modeling, so as to improve the modeling efficiency. The generated model can be effectively in
butt joint with
building design and transformation and related technical
data analysis software in an ideal city building
intelligent modeling and VR display experiment platform, follow-up research work or deepening creation work is carried out, finally, finished product resources in various forms of pictures, videos,
panorama,
roaming and VR are published, building site live-action experience is created, and the development and development of the ideal city building
intelligent modeling and VR display experiment platform is facilitated. Multi-party intelligent interaction is realized; through the assistance of a digital
information acquisition technology, more intelligent surveying and mapping and more efficient modeling are realized; on the basis of a reality model, a design model and technical data, a whole-
process optimization drilling platform under building updating and reconstruction is formed; multi-party intelligent interaction with multi-element interaction and real-
time sharing is realized, and the directness and high efficiency of public communication and multi-party conversation are improved.
