Abstract

The invention provides a real-time virtual-real fusion live system and method based on WebGL. The real-time virtual-real fusion live system and method based on the WebGL uses the WebGL interface to realize an effective method of real-time virtual-real fusion at the Web end. The real-time virtual-real fusion live system based on the WebGL comprises five modules: a video model generation module, a video live module, a GIS service module, a virtual-real fusion module and a scene controller module. The real-time virtual-real fusion live system based on the WebGL realizes the display effect of real-time virtual-real fusion of multiple video streams on the Web end, improves the matching accuracy of virtual-real fusion display, and has the advantages of less required resources, good cross platform compatibility and good extensibility.

Description

technical field [0001] The invention belongs to the technical field of virtual reality in computer vision, and mainly relates to a real-time virtual reality fusion live broadcast system and method based on WebGL. Background technique [0002] With the development of computer graphics technology and Internet technology, traditional two-dimensional images are gradually unable to meet the needs of modern people for displaying and understanding scenes, and the emergence of virtual reality technology makes up for this shortcoming. Therefore, in recent years, virtual reality technology and its related fields have developed rapidly, and are widely used in simulation training, video surveillance, city roaming, military demonstrations, scenic spot display and other fields. [0003] The virtual three-dimensional scene allows users to get a more three-dimensional and real experience. When the environmental information of the virtual scene is more similar to the real environment inform...
