OpenGL中模拟目标与实时场景的融合技术

为了使视景仿真达到实时性和逼真性的双重要求,介绍了一种基于实时视频的真实背景与仿真模型进行融合的仿真场景实现技术.使用视频应用程序软件工具包VFW(Video for Windows)捕获实时视频形成真实纹理,在OpenGL仿真系统中将真实纹理代替传统的三维背景建模,建立了飞机在高空俯视地面的具有层次变化的仿真场景.实验证明这种方法不但简化了视景仿真步骤,节省了背景建模时间,而且增加了逼真度,易于实现场景的快速仿真.

The Fusion Technology of Simulation Target and Real-time Scene Based on VFW in OpenGL

To make the visual simulation achieve the dual demands of real-time and realistic, This article describes a fusion technology that a simulation model and a true background based on real-time video. Use the video application software toolkit VFW (Video for Windows) capture real-time video to form the real texture. Real texture replaces the traditional three-dimensional background modeling in OpenGL simulation system, we established a simulation scene which aircraft at high altitude overlooking the ground with level change. Experiments prove that this approach not only simplifies the visual simulation steps, save time-to-background modeling, but also increases the fidelity and easy to achieve fast simulation of the scene.
