3D virtual community construction method based on panoramic and real image and geographic information

Abstract

The invention relates to a 3D virtual community construction method based on panoramic and real image and geographic information. The method comprises the following steps: establishing a virtual community structure; establishing a virtual community display platform through three procedures, including the first procedure of creating a virtual space based on a scene display outer curtain, creating a virtual ground and setting a wandering mode of a user on the virtual ground; the second procedure of adding a 3D entity on the virtual ground and the third procedure of synchronizing the virtual space and the geographic information of the real world; obtaining a virtual community based on panoramic and real image and geographic information; and enabling the environmental interaction of users in the virtual community and the interaction of a current user and other users. The inventive method increases the virtual community scene construction efficiency, improves the realistic effect, ensures the scene of the virtual community consistent to the scene of the real community, allows the user in the virtual space to not only enjoy the environment of the real world but also know the current geographical location, and enhances the realistic effect of the virtual community.

Description

technical field [0001] The invention relates to a virtual reality technology, in particular to a method for constructing a 3D virtual community based on panoramic real scene images and geographic information. Background technique [0002] The German sociologist Tonis first used the concept of "community" in 1887. Later, the American C.P. Romes translated the German word "community" into English as Community. Community has meanings such as communes, groups, and communities. In modern sociology, although there are hundreds of definitions of community, they can basically be summarized as follows: community refers to a regional living community. [0003] With the rapid development and widespread use of Internet technology, communities that exist in the real world can also exist with the help of network media, called virtual communities. The earliest definition of virtual community (Virtual community) was made by Howard Rheingole, the author of "The Virtual Reality and Virtual ...

AI Technical Summary

Problems solved by technology

However, since the construction of the above 3D virtual community all adopts the 3D modeling method to construct the environment of the virtual community, this method has two main disadvantages: 1) 3D modeling software is based on geometric objects, light sources, viewpoints, entrances, Animation description is used to construct the virtual environment, so the virtual environment constructed by 3D modeling method is poor in simulation, which is very different from the real environment in the real world; 2) The modeling workload is heavy, the efficiency is low, and it is not suitable for large-scale scene construction

At present, there is no report on the 3D virtual community with the above characteristics at the same time.
