虚拟植入技术在气象节目制作中的应用

Application of Virtual Implants Technology in Meteorological Production

随着虚拟图形图像技术的发展,虚拟技术的实践应用已经越来越多样化,从基于蓝箱的无限空间虚拟,到真实场景中的虚拟物体植入,虚拟现实的效果在不断推陈出新,丰富着媒体舞台。气象节目在保证节目实时、高效的播出基础上,结合虚拟植入系统的应用,通过三维地图的亮暗来突出主持人正在播报的地理区域,更加形象、易懂的展示气象情况。打破了一直以来中央电视台传统、单一的气象播报形式。不仅提升了节目的科技性,也丰富了节目的视觉效果,令电视观众眼前一亮。本文主要介绍演播室虚拟植入技术的改造过程以及虚拟技术在气象节目产品中的应用。

With development in virtualised images, the application of this technology has become more diversified. From the unlimited virtualisation of the space using a ＂blue box＂ to embedding the virtualised objects into real scenes, the effect of virtualisation is continuously developing, making the media platform ever more interesting. As well as making sure the weather programs are real-time and high quality, we are now able to combine the weather programs with the embedded virtualisation system by using the brightness on a 3D map, in order to highlight the geographic areas as the presenter goes through the map. This makes it more vivid and easy to understand, and has completely changed the presentation format traditionally adopted by CCTV. Not only did it improve the scientific innovations when making programs but also enriched the visualisation effect of the television programs making the audience more engaged.This article mainly introduces the transformation process and the application of the embedded virtualisation technology in television studios,
