Naked-Eye 3D: A New Trend in the Age of Truth

Reasons for concern: short-term, meta-universe plate ushered in a hype boom, naked-eye 3D is a new trend in the era of full truth, and most virtual people currently use 3D technology and holographic technology.

1. What is naked-eye 3D?

Using the characteristics of parallax between the two eyes, without the need for any auxiliary equipment (such as 3D glasses, helmets, etc.), you can obtain a display system with a realistic stereoscopic image of space and depth. According to the principle of stereoscopic vision, the video image seen by the left and right eyes can feel a three-dimensional three-dimensional space after the processing of the brain, and the naked-eye 3D is to use the principle of the human eye to make the audience feel the realism of the naked-eye 3D.

2. Naked-eye 3D is an important display technology in the field of VR/AR

The basic requirements of mobile terminals for 3D display are still ultra-thin, high light efficiency, high image quality and real three-dimensional experience. At the same time, the naked-eye 3D display must have a "holographic" function, which not only displays 2D information (amplitude, brightness and color), but also provides stereoscopic information (phase), that is, the carrier of 3D image information is the "light field", and the parameters expressing the light field are at least 4 variables. Therefore, regardless of the display mode and function, the image expression of the future 3D display screen will be fundamentally different from the flat display, of which the biggest difference is that the unit expressing the 3D image is no longer "2D pixels", but must be "3D micro-nano structure morphology", in order to achieve the number of variables that display the 3D light field.

3. At present, most virtual people use 3D technology and holographic technology

Douyin virtual beauty master Liu Yexi recently dominated the screen, Xiaohongshu virtual person AYAYI, B station CEO Chen Rui said at this year's 12th anniversary celebration that in the past year, more than 32,000 virtual anchors started broadcasting on B station, an increase of 40% year-on-year, and virtual anchors have become the fastest growing category in the field of B station live broadcasting. Compared with traditional cartoons, 3D rendering technology and holographic technology are mainly applied to achieve naked-eye 3D. At present, the main monetization methods of virtual people include video KOLs, virtual idols, brand endorsements, etc.

4. Naked-eye 3D integrated imaging has potential in conferences and other scenarios

In the future, the naked-eye 3D light field display will move towards the field of consumer electronics with the mass production of equipment, becoming a challenger to existing 2D display devices, and is expected to subvert a variety of scenarios that require 3D and stereoscopic content displays. Including interactive entertainment such as games, advertising and cultural creation, video conferencing, medical imaging, scientific research and education, etc. Advantages: naked-eye viewing, large viewing range, continuous viewing angle, support for multi-person viewing; challenges: reflection field, texture acquisition and reconstruction require high-precision equipment, multi-angle shooting content, picture reconstruction, compression requires algorithm support, streaming media codec transmission has high network requirements.
