Description

一种裸眼3D成像的光路系统Optical path system for naked eye 3D imaging

技术领域technical field

本发明涉及立体视觉显示的光路技术领域，尤其涉及一种立体成像方法、观看3D图片和视频的裸眼3D显示光路系统。The invention relates to the technical field of optical paths for stereoscopic vision display, and in particular, to a stereoscopic imaging method and a naked-eye 3D display optical path system for viewing 3D pictures and videos.

背景技术Background technique

随着科技的不断发展，人们对立体视觉体验的要求越来越高，但是去3D电影院或者购买3D电视，在观看的同时需要佩戴3D眼镜，或者采用头戴式的3D显示设备等方法，这些限制因素为人们体验3D带来了一定的不便，无法满足人们裸眼正常观看3D视频的要求。如何舍弃3D眼镜和其他一些辅助设备的负担来观看3D视频成为我们工作的主要目的。With the continuous development of science and technology, people have higher and higher requirements for stereo vision experience. However, when going to a 3D cinema or buying a 3D TV, you need to wear 3D glasses while watching, or use a head-mounted 3D display device and other methods. The limiting factor brings certain inconvenience to people's experience of 3D, and cannot meet the requirement of people to normally watch 3D video with naked eyes. How to abandon the burden of 3D glasses and some other auxiliary equipment to watch 3D video becomes the main purpose of our work.

人眼视觉系统采用单眼感知时，可以感知二维世界，而采用双眼感知时，可以利用视差感知立体世界。立体视觉显示的方法是利用人眼成像的原理来制造视差，因为人的两眼有65毫米左右的间距，看到同一物体不同角度的两幅图像，经人大脑合成产生立体视觉感。用两台距离为人眼距离的微型摄像头并排来模拟人眼，同时拍下图像或视频后让人眼观看到不同的效果，可以产生立体视觉。在此基础上，可以发展出很多的3D显示技术。对于裸眼观看3D视频来说，观看者不需要凭感觉调整视线才能获得立体感，因此也适合用于低年龄段的用户。相较于头戴式的3D显示设备，裸眼观看能够减轻头部负担，并且出瞳距离较大，可以使观看者更加轻松。When the human visual system adopts monocular perception, it can perceive the two-dimensional world, and when it adopts binocular perception, it can perceive the three-dimensional world by using parallax. The method of stereo vision display is to use the principle of human eye imaging to create parallax, because human eyes have a distance of about 65 mm, and they see two images of the same object from different angles, which are synthesized by the human brain to produce a sense of stereo vision. The human eye is simulated by two miniature cameras with a distance of the human eye distance, and the human eye can see different effects after taking an image or video at the same time, which can produce stereoscopic vision. On this basis, many 3D display technologies can be developed. For naked-eye viewing of 3D video, the viewer does not need to adjust the sight line by feeling to obtain a three-dimensional effect, so it is also suitable for users of younger age groups. Compared with head-mounted 3D display devices, naked-eye viewing can reduce the burden on the head, and the exit pupil distance is larger, which can make it easier for the viewer.

申请号为CN108181707A、名称《一种3D成像方法、视觉光路系统以及头戴式显示设备》的中国专利，含1、第一屏幕；2、第二屏幕；3、左快门式镜片；4、右快门式镜片；5、光学镜片；6、半透半反镜片，其特征在于，控制第一屏幕1和第二屏幕2交替放映影像，使左快门式镜片和右快门式镜片之间的切换频率与第一屏幕和第二屏幕放映影像的交替频率保持一致。The Chinese patent with the application number CN108181707A, titled "A 3D Imaging Method, Visual Optical Path System and Head Mounted Display Device", includes 1. the first screen; 2. the second screen; 3. the left shutter lens; 4. the right Shutter lens; 5. Optical lens; 6. Transflective lens, characterized in that the first screen 1 and the second screen 2 are controlled to alternately display images, so that the switching frequency between the left shutter lens and the right shutter lens Be consistent with the alternating frequency of the images shown on the first screen and the second screen.

其存在的不足之处：控制系统复杂，并且成像的清晰度不能保证，以及加重了人体头部的承重，长时间观看可能疲劳或者眩晕。Its shortcomings: the control system is complicated, and the clarity of the imaging cannot be guaranteed, and the weight of the human head is increased, which may cause fatigue or dizziness when viewing for a long time.
