摘要

摘要:
随着数字化展示技术的不断发展，展陈方式也发生了改变。佩伯尔幻象的展陈空间的光环境在保证效果的同时，还具有较好的视觉舒适性。为探寻光环境对佩伯尔幻象展示效果的影响，搭建了虚拟成像展示空间，研究了影响成像效果的因素与趋势。研究设定12组不同照度和色温组合的LED光照参数，选取25名观察者进行心理物理学实验，以分析不同光环境对佩伯尔幻象展陈效果的影响。通过实验可知：色温对幻象中的色彩真实度、细节表现力、立体感表现力评价影响较低；照度对色彩真实度评价未产生显著影响，对它的细节表现力、立体感表现力具有显著性影响，在色温为3500 K，照度为10 lx的光环境下，展示效果中的细节表现力、立体感表现力相对较高，在色温为2500 K、照度为10 lx时视觉舒适度较好。

Abstract:
With the continuous development of digital display technology, display methods have also changed. Pepper’s ghost images that adopt modern display methods require the light environment of the exhibition space not only to ensure the effect but also ensure better visual comfort. In order to explore the influence of the lighting environment on the display effect based on Pepper’s ghost images, a virtual imaging display space is set up to analyze the factors and trends affecting the imaging effect, in which 12 sets of LED lighting conditions with different illuminances and color temperatures are generated. 25 observers are selected to conduct a psychophysical experiment. The experiment shows that color temperature has no significant effect on the evaluation of color authenticity, detail expressiveness and stereoscopic expressiveness for Pepper’s ghost images; illumination has no strong effect on the evaluation of the color authenticity of Pepper’s ghost images, but has a significant effect on their detail expressiveness and stereoscopic expressiveness. Under the lighting environment where the color temperature is 3500 K and the illumination is 10 lx, the detailed expressiveness and stereoscopic expressiveness of the display effect are relatively high and the visual comfort of 2500 K and 10 lx is better.
