摘要
介绍了一种基于PC机群构造沉浸式多通道投影显示系统的方法。使用PC机和普通投影仪构建了硬件系统,提出了基于软件的交互式几何校正方法和基于线性函数的边缘融合方法,快速地完成几何畸变校正和通道间的拼接融合,消除了投影画面之间的缝隙。这种方法在满足同等投影显示要求的情况下,大幅度地降低了系统的构建费用和维护要求,具有良好的实际应用价值。
A kind of method was given for building multi-projection immersive display system based on PCs. Some researcn has been done on the geometric rectification and edge blending of multi-projector displays. An interactive software-based geometric registration technique was used to calibrate the deformed image projected on the surface ,and to align the projection image with each other. Luminance attenuation algorithm based on linear ramp was proposed to blend intensity on projector overlapped regions. The experimental results show the method is effective.
