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 vi

Embodiment 2

[0152] The difference from Embodiment 1 is that: the shape of the scene display outer curtain is a cubic space (regular hexahedron).

[0153] The method of adding 3D entities in the virtual community is to use the 3D graphics program interface to create 3D entities inside the virtual space, as follows:

[0154] During the roaming process, the user will observe some buildings or places in the outer screen of the cube panoramic real-view display, but in the real scene, many buildings and places have no obvious identification marks. In this embodiment, a 3D graphics program interface is used to add 3D entities to the outer screen of the cube panoramic real-scene display. This embodiment takes a virtual signage as an example to solve the problem of scene recognition for users in the process of roaming in a virtual community. The specific implementation method is as follows: :

[0155] In the 3D entity management unit 14 of the server, the attribute information of the 3D virtual s...

Embodiment 3

[0161] The difference from Embodiment 1 is that the scene display outer curtain is shaped as a cylindrical space, and the scene display outer curtain structure of the present invention can also be created as other closed space geometry.

[0162] The method of adding 3D entities in the virtual community is to create 3D entities in the virtual community by using the 3D graphics program interface, and import the 3D entity models created outside the 3D display platform 16 into the mixed reality space of the virtual community.

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 geographical 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 Virtua...
