Method and system for collaborative modeling of virtual scene based on mobile terminal and holographic display

Abstract

The invention discloses a collaborative modeling method and system based on a mobile terminal and a holographic displayed virtual scene. The method includes constructing a holographic three-dimensional projection device connected to a server; connecting a mobile terminal with the server in one wireless local area network; acquiring and inputting the two-dimensional planar design graph and layout drawing or pre-stored planar graph of the three-dimensional virtual scene into the system; allowing high priority users to draw or adjust the virtual scene wall in a two-dimensional scene drawing unit according to the input scene planar design graph, and generating a three-dimensional scene in the virtual environment in real time; allowing model adding units of multiple mobile terminals to add models of the virtual scene collaboratively; allowing a natural interaction unit to determine the holographic displayed three-dimensional virtual scene; storing the two-dimensional planar design graph of the three-dimensional scene, and outputting the three-dimensional scene. The accuracy of scene arrangement is improved, the collaborative modeling for communication between the mobile terminal and the server is implemented for users, the collaboration of the virtual scene design is improved, and the producing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional virtual scene modeling, in particular to a virtual scene collaborative modeling method and system based on a mobile terminal and a holographic display. Background technique [0002] Virtual Reality (VR for short) is a comprehensive technology involving human-computer interaction, computer graphics and artificial intelligence. Its purpose is to use computers to generate a realistic three-dimensional sensory world, giving users a real-world experience. Virtual reality technology is currently playing a huge role in games, animation, advertising, architectural design, military simulation and other fields, and the construction of virtual scenes is a crucial step in the process of building virtual reality systems. [0003] At present, there are three main ways to build virtual scenes: the first is to use 3D modeling software to build directly, and manually place the models one by one ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are three main ways to build virtual scenes: the first is to use 3D modeling software to build directly, and manually place the models one by one to form the overall environment of the 3D scene, and finally use virtual reality technology to display the environment The disadvantages are high threshold, complex operation, and poor coordination; the second is based on 3D laser scanning and other technologies to obtain color video image data, and obtain fast 3D modeling of the scene through computer processing. The disadvantages are high hardware requirements and measurement costs. High, requiring a lot of manual modification; the third is parametric modeling, input parameters, dimensions to determine feature dependencies to build a scene, the disadvantage is that users must master a specific computer language and have certain programming skills
