摘要
在虚拟演播室的组成结构的基础上,对其中的虚拟场景成像技术和摄像机跟踪技术这两项关键技术进行了较深入的研究。虚拟演播室系统以VC++作为开发平台,O penGL作为图形程序接口,设计并实现了一个3D图形引擎中的渲染器模块,非常直观地展现了丰富、逼真、多变的教学场景。
The building of virtual studio in college has been a growing concern in educational technology. This article discusses the structure and composition of the virtual studio, and two of it＇s key technologies ： virtual scene imaging cameras and tracking technology. They were detailedly analyzed; By using VC ＋＋ as developing platform, OpenGL as graphics API , we designed a 3D graphics rendering engine module, and laid the foundation for furtherlly research; the practical applications of virtual studio in medical colleges teaching was briefly discussed in the end.
