基于网络CAVE系统的搭建及图像的几何校正

The CAVE System Set up and the Geometric Correction of Image Based on the Network

摘要: 本文讨论了一个搭建CAVE系统的方法。本系统的搭建由网络同步控制和图像校正显示两部分组成，网络同步控制整体上是一个主从式分布式网络结构，每台电脑之间通过同步卡进行连接，保证系统在最小的相应时间内可以并行发送指令。主服务器负责交互控制，其他电脑接受主服务器的命令和实时绘制、显示立体图像。图像校正显示部分主要研究了图像的几何校正算法，实现了对不平整投影幕的异性校正。通过在不同的虚拟漫游场景中进行测试，可以达到每秒60帧图像的显示速率，图像矫正占据每帧绘制时间大约5%，表明该系统具有良好的推广前景和较高的实用价值。

Abstract: This paper discusses a method of building CAVE system. The structure of the system is com-posed of two parts, which are network synchronization control and image correction. The net-work synchronization control is a master-slave distributed network structure, which is con-nected with each computer, ensures that the system can send instructions in parallel in a mini-mum of time. The main server is responsible for interactive control, other computers to accept the main server commands and real-time rendering, display three-dimensional image. The im-age correction display part mainly studied the geometric correction algorithm of the image, and achieved the opposite sex of the projection screen. By testing in different virtual roaming scena-rios, the display rate of 60 frames per second can be achieved, and the image correction occu-pies about 5% of the time per frame, which indicates that the system has a good prospect and practical value.
