在传统的立体显示器中，焦点提示是不正确的。这会导致融合和适应的分离，从而导致视觉疲劳和知觉扭曲。多平面显示器可以通过创建几乎正确的焦点提示来最大限度地减少这些问题。但要在多平面显示中创建连续深度的外观，需要使用深度加权混合：即在相邻平面之间分布光强度。Akeley等人。[ACM Transans.图表。23,804(2004)]和刘和华[选择Express 18,11562(2009年)]描述了相当不同的深度加权混合规则。我们使用一个典型的人眼模型和生物学上可信的图像质量指标来检验这些规则和其他规则的有效性。我们发现Akeley和他的同事提出的线性混合规则[ACM Trans.图表。23,804(2004)]是自然刺激的最佳解决方案。(C)2011年美国光学学会
Focus cues are incorrect in conventional stereoscopic displays. This causes a dissociation of vergence and accommodation, which leads to visual fatigue and perceptual distortions. Multi-plane displays can minimize these problems by creating nearly correct focus cues. But to create the appearance of continuous depth in a multi-plane display, one needs to use depth-weighted blending: i.e., distribute light intensity between adjacent planes. Akeley et al. [ACM Trans. Graph. 23, 804 (2004)] and Liu and Hua [ Opt. Express 18, 11562 (2009)] described rather different rules for depth-weighted blending. We examined the effectiveness of those and other rules using a model of a typical human eye and biologically plausible metrics for image quality. We find that the linear blending rule proposed by Akeley and colleagues [ACM Trans. Graph. 23, 804 (2004)] is the best solution for natural stimuli. (C) 2011 Optical Society of America
