一个通用的投影墙软件校正系统

随着计算机图形硬件以及分布式并行图形绘制技术的不断发展，现在图形工作站以及PC集群机所能处理的图形数据量不断上升。但是，现在计算机显示设备所能提供的显示分辨率及其有限。因此，利用多台投影仪组成投影阵列进行拼接显示的投影墙技术受到越来越多的关注；此类系统的一个关键问题就是如何校正多台投影仪，使得最后拼接显示的图像没有明显的缝隙和瑕疵。该文介绍了一套通用的与具体应用无关的投影墙软件校正系统，该系统克服了传统软件校正系统在通用性、校正速度等方面的不足，取得了很好的校正效果。

A Current Display Wall Software Calibration System

With the development of computer graphics hardware and distributed parallel rendering, the rendering capabilities of graphics workstations and PC clusters have improved a lot. But, the display resolution of monitors is far from enough. So, more and more people are focusing on using multiple projectors to form a display wall and provide large display resolution; one key problem of these kinds of systems is how to calibrate the projectors and makes the whole display seamless and perfect. This paper presents a universal display wall calibrating system which is independent of specific appfications. And the system has successfully solved the traditional problems of universality, calibrating speed, and can achieve great calibrating results.
