立体环幕影像低成本解决之道--基于HLSL后处理技术的三通道立体投影方法研究

摘要

Because of the expensive investment, stereoscopic cylindrical cinemas are hard to find in educational institutions. And therefore, domestic creators for cylindrical screen and 4D cinemas are rare, and iflms from abroad reign this market. This article puts forward a solution employing one single computer to actualize 3-channel stereo projection on cylindrical screens, bringing down the cost dramatically. Using HLSL codes, the processing power in GPU is invoked to perform geometric correction and edge blending in real time. Finally, the mechanism proposed in this article was tested and analyzed, and a conclusion is drawn about its advantages, disadvantages and future development.%立体环幕影像由于其放映系统成本高昂，很难在教育机构中普及，因此国内环幕及4D影片创作力量匮乏，片源长期依赖进口。为了降低创作成本，本文提出了只需单台电脑便可实现三通道立体投影的解决方案，通过HLSL语言调用显卡GPU强大的计算能力实现实时的几何校正与边缘融合。最后，文章对该解决方案的实际应用效果进行了测试与分析，并阐述了其优缺点与未来研究方向。
