摘要
三维(three-dimensional,3D)显示技术是元宇宙等领域的关键技术,通过3D显示设备进入元宇宙可以将虚拟世界与现实世界进行密切融合.介绍了3D显示的概念和分类,阐述了3D显示与元宇宙的关系.再介绍集成成像(integral imaging,InIm)3D显示技术的发展历程.考虑到集成成像3D显示技术的发展主要受限于3D分辨率低、观看视角窄、景深小等因素,分析了集成成像3D图像性能不佳的根本原因,并介绍了国内外解决这些问题的研究进展.随着科学技术的不断进步,集成成像3D显示性能将会得到进一步提升并在元宇宙领域发挥重要作用.
Three-dimensional(3D)display technology is a key technology in metaverse and other fields.Using 3D display into the metaverse can merge the virtual world closely with the real world.The concept and classification of 3D display are firstly introduced,and the relationship between 3D display and metaverse is expounded.Then the development history of integral imaging(InIm)3D display technology is introduced.Considering that the development of InIm 3D display technology is limited by low resolution,narrow viewing angle,and limited depth of field of 3D images.The root causes of the poor performances of the InIm 3D images are analyzed,and the latest progress in solving these problems at domestic and abroad is introduced.With the continuous progress of science and technology,the performances of the InIm 3D display will be further enhanced,and the InIm 3D display will play an important role in the metaverse field.
