【摘要】：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。
[Abstract]:In order to accurately and objectively evaluate and optimize the flicker phenomenon in solid volume true 3D display, a light valve matrix refresh method based on interlayer scanning is proposed. Fourier transform is used to analyze the energy distribution of imaging optical signals in frequency domain under different scanning modes. Based on the evaluation model of time-contrast sensitivity function weighted amplitude spectrum intensity and CSWAs, the energy distribution of imaging optical signals in different scanning modes is analyzed. A time contrast sensitivity function weighted amplitude spectrum contrast method is proposed. The Pearson correlation coefficient between the results of two groups of visual perception experiments and the estimated results of CSWC evaluation model was -0.99. The results show that the proposed method can reduce the scintillation of the true 3D display and the CSWC evaluation model can realize the objective quantitative evaluation of the true 3D display scintillation degree. The results play a positive role in guiding and promoting 3D display flicker degree optimization and viewing comfort improvement based on the principle of depth fusion.
