Embodiment 1

[0071] The method of the present invention uses the panoramic real scene image as the scene background and organically combines the 3D modeling entity into the scene constructed by the panoramic real scene image. Such a computer virtual scene fused on the scene content is called hybrid reality.

[0072] The hybrid reality platform construction method of the present invention is based on such figure 1 Based on the system structure shown, the system structure includes: the data management background 11 is composed of a database 12 , a data storage unit 13 , and a 3D entity management unit 14 ; the application program interface 15 is composed of a 3D display platform 16 and a geographic information platform 17 .

[0073] The application program interface 15 requests data (including panoramic real scene image data and geographical information data) from the data management background 11 for roaming in the mixed reality space.

[0074] The data storage unit 13 is a disk space reser...

Embodiment 2

[0127] The difference from Example 1 is:

[0128] The shape of the scene exterior is a cubic space (regular hexahedron).

[0129] The method of adding 3D entities in the mixed reality space is to use the 3D graphics program interface to create 3D entities inside the mixed reality space, as follows:

[0130] 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 graphic 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 mixed reality space. The specific implementation method is as follows: :

[0131] In the 3D entity management unit 14 in the data management background 11, the attribute informatio...

Embodiment 3

[0133] The difference from Example 1 is:

[0134] The shape of the scene exterior is a cylindrical space.

[0135] The method of adding a 3D entity in the mixed reality space is to create a 3D entity in the mixed reality space by using a 3D graphics program interface, and import the 3D entity model created outside the 3D display platform 16 into the mixed reality space.

[0136] The scene exterior curtain structure of the present invention can also be created as other enclosed space geometry.

Abstract

The invention discloses a construction method of a panoramic / realistic hybrid reality platform, which comprises the following specific steps: acquiring panoramic picture data, geographic information data and other original data required for constructing a hybrid reality platform, and storing in a data storage unit of a data management background; then, creating a hybrid reality panoramic / realistic display curtain, creating a virtual ground and adding 3D entities to construct a hybrid reality space based on panoramic pictures; and finally, synchronizing the hybrid reality space with the geographic information of the real world. By organically combining the real scene with the 3D entities in the virtual space, the invention enables users to have strong space reality feeling and immersion feeling in the process of roaming in the hybrid reality space.

Description

technical field [0001] The invention relates to virtual reality technology, in particular to a method for constructing a panoramic real-scene hybrid reality (HybridReality) platform. Background technique [0002] In recent years, virtual reality technology is a research hotspot in the field of information technology at home and abroad. Traditional virtual reality technology reproduces the three-dimensional landscape of the real world through 3D-based environmental modeling technology. For example, Virtual Philadelphia (Virtual Philadelphia) uses 3D modeling to model every building in Philadelphia in a virtual space, and users can virtually roam the streets of Philadelphia. Another example is virtual communities, such as Second Life (Second Life), which are also modeled in space by 3D tools. The difference with the former is that the modeling of the environment in the community can be done by the users themselves. The advantage of using 3D modeling technology to build a vir...
