基于人眼视觉的集成成像三维显示分辨率的比较

摘要

In order to present the visual resolution effects of different integral imaging systems in three-dimensional （3D） display applica- tions, a method of comparing the resolutions of integral imaging 3D display based on human vision is proposed. The relative resolution parameter is defined by analyzing the relation between the integral imaging 3D system and resolving power of human eyes on the best viewing condition, and its relationship with the visual resolution effect viewed in the integral imaging 3D display system is analyzed. The results indicate that the size of lens array has an important influence on the visual resolution effect in the integral imaging 3D display system. According to the theoretical results of two examples show that the difference in relative resolution parameter between the systems is 1.75 times of that of traditional one. The experimental results are consistent with the theoretical analyses. The method proposed in this paper could have a certain directive significance for 3D display resolution evaluation.%为了对不同集成成像系统三维显示应用中的视觉分辨效果进行表征，提出了一种基于人眼视觉的集成成像三维显示分辨率的分析比较方法．通过分析集成成像三维显示系统的分辨率与人眼在最佳显示观看距离下分辨本领的关系，定义了相对分辨率参数，分析了其与集成成像三维显示实际观看时视觉分辨效果的关系．研究结果表明，透镜阵列的大小对集成成像三维显示的视觉分辨效果有重要的影响．针对两个系统实例的理论计算结果表明，系统间的相对分辨率参数差异是传统分辨率差异的1．75倍，实验结果与理论分析一致．该研究方法对三维显示分辨率的评价有一定的指导意义．
