Broadcast True3D Digital Virtual Studio Technology Research And Implementation

With the rapid development of computer graphics technology and the increasing demands of digital media, a new television program production system,"virtual studio system" to the rapid development and wide application of use of the system can not only reduce programming costs, improve the efficiency of program production, and can give full play to the director and program staff creativity, no longer subject to time, space and props and other conditions."True three-dimensional virtual studio system" is integrated into the camera tracking technology and computer three-dimensional virtual technology can be integrated into the host’s virtual three-dimensional scene, adding virtual lighting, virtual props, etc., to make the effect more realistic, creative ideas and more open. In recent years, the television media becoming more competitive, more attention to the development and introduction of new technologies, including "true three-dimensional virtual studio system" by virtue of the unique characteristics of the propagation and dissemination of results received widespread attention.This paper discusses the virtual studio technique to study the true three-dimensional virtual studio key technologies, such as video cameras tracking technology and three-dimensional computer graphics technology, according to Jinan TV true three-dimensional virtual studio system project of the actual situation, combined with the most advanced virtual studio room technology proposed architecture virtual studio system solutions.In addition, the authors combine their work experience, Jinan TV "Mystery Hour" program in true three-dimensional virtual studio system application projects, for example, design a meet part of their needs dimensional virtual scene, detailing pre-program research, design creativity, specific design and the ultimate in true three-dimensional virtual studio Jinan TV system debugging application effects, etc., to show true three-dimensional virtual studio system advantages, summarize experience in the design, three-dimensional virtual studio system designed to provide an idea of the virtual scene, engaged in related work peers provide reference.
