摘要
为解决使用游戏引擎进行影视灯光设计和布光预演时,虚拟环境中光源光度学特性与真实的灯光不匹配的问题,结合已有的灯具光强分布测试系统,提出针对影视LED光源光强分布的测试方案;基于实测数据,在虚幻引擎5中构建了一套光源校准流程,以在虚拟环境中准确模拟光源的光度学特性。仿真结果表明:该校准流程能较准确且高效地在UE5中还原光源的光强分布。为影视工作者在UE5中进行灯光虚拟仿真提供优化方案,为影视虚拟制作中的照明匹配提供新的理论支撑和技术支持。
To address the issues of mismatched photometric characteristics between light sources in virtual environments and real-world lighting during film and television lighting design and lighting preview using game engines,a testing solution for measuring the luminous intensity distribution for film and television LED light sources was proposed,building upon existing luminaire light intensity distribution testing systems.Based on the obtained data,a light source calibration process was constructed in the UE5 to correctly simulate the photometric characteristics of light sources in the virtual environment.Simulation results have shown that the calibration process can accurately and efficiently reproduce the luminous intensity distribution in UE5.This study proposes an optimized solution for lighting virtual simulation in UE5,providing new theoretical and technical support for lighting matching in virtual production of film and television.
