【摘要】：集成成像具有裸眼观看、无立体观看视疲劳、全真再现等优点,是目前主流的一种裸眼3D显示技术。在集成成像3D显示器研制过程中,由于微图像阵列尺寸不等于显示器像素的整数倍,将产生微图像阵列尺寸的缩放,同时由于集成成像3D显示器装配误差或微透镜阵列制作工艺精度不够等问题,将使得微图像阵列相对于微透镜阵列产生一定程度的平移。针对微图像阵列尺寸缩放和平移对集成成像重建的3D图像在图像深度和3D观看视角方面的影响问题,本文基于几何光学原理,采用集成成像图像重建技术和视角分析方法,分别分析微图像阵列尺寸缩放和平移时重建3D图像的深度及3D观看视角的变化情况。通过计算机模拟再现实验和实际的光学再现实验对理论分析进行了验证。模拟再现实验结果表明,3D图像深度随着微图像阵列尺寸的放大而减小,反之则增大;光学再现实验结果表明,3D观看视角随着微图像阵列尺寸的放大而增大,反之则减小,微图像阵列平移对3D观看视角产生了一定的平移,而对3D观看视角大小的影响甚微。根据模拟再现实验和光学再现实验结果得出的结论,微图像阵列缩放将引起3D图像深度畸变和3D观看视角的改变,而微图像阵列平移对集成成像3D显示的影响较小。该研究结果将为集成成像3D显示器的研制和优化起到实际的指导作用。
[Abstract]:Integrated imaging has the advantages of naked eye viewing, no stereoscopic visual fatigue, full true reproduction and so on, so it is a mainstream naked eye 3D display technology. In the process of developing integrated imaging 3D display, because the size of microimage array is not equal to the integer times of display pixel, the size of microimage array will be scaled. At the same time, due to the assembly error of 3D integrated imaging display or the insufficient fabrication precision of microlens array, the microimage array will have a certain degree of translation relative to the microlens array. Aiming at the influence of the size scaling and translation of the microimage array on the depth of the 3D image and the viewing angle of the 3D image, based on the principle of geometric optics, the integrated imaging image reconstruction technique and the method of angle analysis are adopted in this paper. The depth of the reconstructed 3D image and the change of the 3D viewing angle are analyzed respectively during the scaling and translation of the microimage array. The theoretical analysis is verified by computer simulation and optical reproduction experiments. The experimental results show that the depth of 3D image decreases with the magnification of the microimage array size, whereas the optical reproduction experiment results show that the 3D viewing angle increases with the magnification of the microimage array size, and vice versa. The translation of microimage array has a certain translation on 3D viewing angle, but has little effect on 3D viewing angle. According to the results of simulation and optical reproduction experiments, the depth distortion of 3D image and the change of 3D viewing angle will be caused by the scaling of microimage array, while the translation of microimage array has little effect on the 3D display of integrated imaging. The research results will play a practical role in the development and optimization of integrated imaging 3D display.
