基于虚拟现实技术的室内单色光环境构建方法

Construction Method of Indoor Monochromatic Lighting Environment Based on Virtual Reality Technology

近年来,虚拟现实技术发展迅速,应用范围广泛。梳理了虚拟现实技术应用于光环境模拟的发展和方向,介绍了虚拟现实技术在光环境模拟领域的实现方式,研究单色光环境可视化,最后基于北京建筑大学室内光环境模拟试验室,进行了虚拟单色光环境构建,对现实光环境与虚拟光环境参数进行了测量,并组织114名在校大学生作为被试对现实光环境与虚拟光环境进行视觉一致性、愉悦度、唤醒度、视觉舒适度量表评价。探讨了兼顾有效性和操作性的虚拟现实光环境构建方法,探索了与现实单色光环境视觉感受趋近一致的虚拟光环境构建方式,进而对现实光环境与虚拟光环境进行评价,结果表明:虚拟光环境在光色和亮度方面可以比较真实的还原现实光环境,但对于某些色相的单色光还原度偏差较大;现实光环境与虚拟光环境在愉悦度、唤醒度、视觉舒适度方面表现出较高的一致性。

In recent years,virtual reality technology has developed rapidly and has a wide range of applications.The development and direction of virtual reality technology applied to lighting environment simulation are sorted out,the implementation of virtual reality technology in the field of lighting environment simulation is introduced and the visualization of monochromatic lighting environment is studied.Finally,based on the real lighting environment scene in the indoor environment simulation laboratory of Beijing University of Civil Engineering and Architecture,the virtual monochromatic lighting environment construction is carried out,the real lighting environment and virtual lighting environment parameters is measured,and a total of 114 university students is organized to evaluate on the visual consistency and emotional scales of the real and virtual lighting environments.In the study the construction method of virtual reality lighting environment with both validity and operability is explored,and the construction method of virtual lighting environment that was consistent with the visual perception of real monochromatic lighting environment is researched,and then the virtual and real lighting environment are evaluated.The results show:the virtual reality light environment can reproduce the real light environment more realistically in terms of light color and luminance,but the reproduction degree of monochromatic light for certain hues is larger;the real and virtual lighting environments show high consistency in terms of emotional pleasure,arousal,and comfort.
