虚拟照明系统的HDR光照渲染关键技术研究

Research on the key technology of HDR illumination rendering in virtual lighting system

以初步构建的虚拟演播室照明系统为基础研究模型,对HDR高动态光照技术的渲染关键技术进行探索研究,并对原有的虚拟照明系统进行优化改进。主要探讨如何利用HDR高动态光照渲染技术,为已建立的虚拟演播室照明系统实现更加真实的光照效果,提高该系统对人眼视觉感受的模拟程度,打造更加逼真、出众的仿真实训环境,展现更具临场感和层次化的光照效果,增强仿真效果的真实性、精确性和实用性,以达到影视动漫专业辅助教学的需要。

In this paper, the key technology of HDR high dynamic illumination technology is studied, and the original virtual lighting system is optimized, based on a preliminary virtual studio illumination system research model. It mainly discusses how to use HDR high dynamic light illumination rendering techniques for virtual studio lighting system established to achieve more realistic illumination effect, improve the system of human visual perception simulation degree, to create a more realistic, superior simulation training environment, show more telepresence and levels of light effects, to enhance the simulation effect of authenticity, accurate and practical. In order to meet the needs of the film and tele- vision animation professional aided teaching.
