摘要：我们的研究旨在开发一种基于使用极高分辨率投影仪的积分摄影方法的空间成像型积分三维（3D）显示器。投影式整体 3D 显示的一个问题是投影元素图像中的几何畸变会导致显示的 3D 图像的空间变形。在本研究中，分析了元素图像的几何畸变与重建的 3D 图像的空间变形之间的一般关系。一种带有失真补偿器的投影式整体 3D 显示器已经开发出来，它可以实时校正投影图像的几何失真。通过畸变补偿，显示的3D图像的变形显着减少，显示的3D图像的分辨率为182（H）×140（V）像素，视角为24.5°。
Abstract— Our research is aimed at developing a spatial‐imaging‐type integral three‐dimensional (3‐D) display based on an integral photography method using an extremely high‐resolution projector. One problem with the projection‐type integral 3‐D display is that geometrical distortion in projected elemental images causes spatial deformation of the displayed 3‐D image. In this study, a general relationship between the geometric distortion of elemental images and the spatial deformation of reconstructed 3‐D images were analyzed. A projection‐type integral 3‐D display with a distortion compensator which corrects the geometrical distortions of projected images in real‐time have been developed. The deformation of the displayed 3‐D images was significantly reduced by the distortion compensation, and the displayed 3‐D images had a resolution of 182 (H) × 140 (V) pixels and a viewing angle of 24.5°.
