集成成像三维显示系统立体深度的研究
Study on the Stereo Depth of Integral Imaging Three-Dimensional Display System
三维显示 集成成像 立体深度 同名点间距 three-dimensional display integral imaging stereo depth cognominal-points spacing
摘要
针对集成成像三维显示技术的特点,利用相邻元素图像中的同名点间距,计算了集成成像三维显示过程中再现场景的立体深度,通过深入分析系统所能够再现场景的最大和最小立体深度,对集成成像三维显示系统立体深度的再现能力进行了表征。结果表明透镜阵列间距和同名点间距对集成成像三维显示系统再现场景的立体深度有重要的影响,而显示器件的分辨率和透镜间距则决定了系统最终的立体深度再现能力。在理论分析的基础上,通过改变元素图像中的同名点间距,在光学实验上实现了对系统再现场景立体深度的调制。
Abstract
In connection with the characteristics of integral imaging three-dimensional display, the stereo depth of integral imaging three-dimensional display system has been calculated using the cognominal-points spacing in the adjacent elemental images. Through in-depth analyze the maximum and minimum stereo depth reproduced by the system, the reconstructing ability of stereo depth is presented. The results show that the lens array pitch and cognominal-points spacing have important influence on the stereo depth, and then the reconstructing ability of stereo depth in the integral imaging system is determined by the resolution of display device and the lens array pitch. On the basis of theoretical analysis, modulation of the stereo depth of system is realized with optical experiments through changing the cognominal-points spacing.
