  • 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。
