为准确客观评价和优化固态体积式真三维显示中的闪烁现象,提出一种隔层扫描的光阀矩阵刷新方法。采用傅里叶变换分析成像光信号在不同扫描模式下的频域能量分布,在时间对比敏感度函数加权幅值谱强度(CSWA)评价模型的基础上,提出时间对比敏感度函数加权幅值谱对比度(CSWC)方法。两组视觉感知实验的结果与CSWC评价模型的估算结果的Pearson相关系数达到-0.99。结果表明,所提出的隔层扫描方法可以减轻真三维显示的闪烁,所提出的CSWC评价模型实现了对真三维显示闪烁程度的客观量化评价。该结果对基于深度融合原理的三维显示闪烁程度优化和观看舒适度提升起到积极的指导和推动作用。
In order to accurately and objectively evaluate and optimize the flickering phenomenon in solid-state volumetric three-dimensional display, a method of shutter matrix light refreshment is proposed. Fourier transform was used to analyze the frequency energy distribution of imaging optical signals in different scanning modes. Based on the CSWA evaluation model of time contrast sensitivity function, the weighted amplitude spectrum of time contrast sensitivity function Contrast (CSWC) method. The Pearson correlation coefficient between the two groups of visual perception experiments and the estimated CSWC model reached -0.99. The results show that the proposed interlayer scanning method can reduce the flickering of the real three-dimensional display. The proposed CSWC evaluation model realizes the objective and quantitative evaluation of the flickering degree of the true three-dimensional display. The results play a positive role in guiding and promoting the optimization of the three-dimensional display based on the depth blending principle and the improvement of viewing comfort.
