Problems solved by technology

However, there is a lack of effective means in the stage of scene object modeling in the process of virtual scene construction. Since scene object modeling is the main link of the entire virtual scene construction, this will lead to long delay time, high computing resources, and The problem of generating a large amount of data cannot be fundamentally solved

Embodiment Construction

[0036] The technical solutions of the present invention will be further specifically described below through examples.

[0037] figure 1 It is a schematic flowchart of a method for realizing hierarchical modeling of a virtual scene according to the present invention. First, in step S1, a virtual scene is obtained, and scene objects included in the virtual scene are extracted.

[0038] Obtaining the virtual scene and extracting the scene target therefrom can be realized by various means, including but not limited to the following means introduced here. For the virtual reality of real scenes that exist in real life, images of the real scene can be taken, for example, a stereoscopic imaging camera system can be used to perform a full range of real scene shooting to obtain images from various viewpoints of the scene, and, using the target The segmentation and extraction algorithm recognizes each scene object contained in the real scene after converting the real scene into a virt...

Abstract

The invention provides a hierarchical modeling method and system of a virtual scene. The significance degrees of different scene objects in the virtual scene are analyzed to determine the different hierarchies of the scene objects in the virtual scene; corresponding scene object models of different complex degrees are selected from the scene objects in the different hierarchies; and different factors of each scene object are classified into hierarchies according to the influential degree on the display effect of virtual reality, and object factors for modeling are decided correspondingly according to the scene objects in different hierarchies. Thus, operation and communication resources are distributed reasonably in the virtual scene modeling process, the instantaneity of the whole process is improved, and the method and system can be applied to different types of network virtual reality platforms.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a method and system for realizing hierarchical modeling of a virtual scene. Background technique [0002] The very popular virtual reality technology in recent years is based on the comprehensive application of computer 3D graphics technology, sensing technology, human-computer interaction technology, and 3D display technology to present users with a highly realistic 3D visual perception and realize 3D display. The high real-time interaction between the world and the user's real-world behavior makes the user experience an experience infinitely close to the real world. The ability to produce immersive effects is an important feature of virtual reality technology that distinguishes it from other graphic display and human-computer interaction technologies. In the environment created by reality, it is difficult to consciously and subconsciously divide the virtual reali...
