In addition, the rapid progress of AR/VR technology since 2014 has also brought new market opportunities for naked-eye 3D. At present, the entrepreneurial hotspot in the VR field is shifting from hardware to content, and these VR contents can theoretically be applied to naked-eye 3D devices. of. Outdoor large-screen naked-eye 3D has entered people's lives and will bring people a different experience.
Today, the editor of LCF will share with you the current principle of naked-eye 3D technology; the naked-eye stereoscopic display is a new generation of autostereoscopic display equipment based on the human eye stereoscopic vision mechanism. It can obtain images with complete depth information without the aid of any visual aids (such as 3D glasses, helmets, etc.). Autostereoscopic display devices can provide true 3D images using multi-channel autostereoscopic display technology. According to the principle of parallax barrier, it uses a specific mask algorithm to arrange the display images interactively, and then capture and observe by both eyes after passing through a specific parallax barrier. The parallax barrier accurately controls the light transmitted by each pixel through the grating array (accurately installed on the LCD panel of the display using the Moiré interference fringe discrimination method), so that only the right eye or the left eye can see it. The angle is different, and the light can be blocked by this angle difference to assign the image to the right eye or the left eye, and the two different images are synthesized into an image with spatial depth and dimension information through the brain, so that you can not Requires any visual aids (such as wearing 3D glasses) to see 3D images.

Bring a bright visual impact to the viewers. With the help of the phantom imaging system, the outdoor large screen naked-eye 3D can not only make the screen more high-definition, but also the digital application concept has achieved the true restoration of 3D for each exhibit. The sex is very prominent, and the sexuality has also brought about the improvement, which is often more deeply rooted in the hearts of the people. In the post-production stage, combined with the help of phantom imaging technology, the concept of time-space spanning can be reproduced and restored in a realistic situation. Through a more expansive style display, the content is made more vivid and three-dimensional, which firmly captures the audience's attention. Judging from the current development of naked-eye 3D on large outdoor screens, various signs in the market are creating a very good development space for it, and various favorable conditions in the market are contributing to the development of naked-eye, no matter which aspect it is. Talents from all over the world are actively involved in it, and in the near future, we will definitely see a big difference in naked-eye 3D. However, as far as the current domestic 3D projection technology is concerned, the audience still needs to wear 3D glasses while watching. This small accessory can make many people love and hate going to the cinema to watch 3D movies, and it is even more unfriendly to friends who wear glasses. , and the discomfort caused by wearing 3D glasses for too long has also greatly affected the viewing experience of most people. In addition, the rapid progress of AR/VR technology since 2014 has also brought new market opportunities for naked-eye 3D. At present, the entrepreneurial hotspot in the VR field is shifting from hardware to content, and these VR contents can theoretically be applied to naked-eye 3D devices. Yes, outdoor large-screen naked-eye 3D has entered people's lives. During the operation, the doctor needs to repeatedly switch the line of sight between the image display and the operation area, which results in a waste of time. Due to fatigue, the phenomenon of visual persistence and visual delay may cause errors in the operation. area, binocular stereo-guided surgery based on a head-mounted display or a stereo surgical microscope.
It can specifically display the real three-dimensional effect of the object, and can better display all aspects of the object. The naked-eye 3D display can intuitively and effectively present the object in front of the viewer, allowing the viewer to immerse himself in the scene, so as to have a clear sensory cognition of the object. This is the visual sensory experience so far. A museum is a place for collecting, archiving, exhibiting and studying objects representing natural and human cultural heritage. Here, both ancient calligraphy and paintings and famous antiques have been truly reproduced. However, when looking at the display styles of domestic museums, most of them are the same, which is difficult to attract people's attention. Over the years, with the emergence of phantom imaging technology, the museum's internal exhibition halls and the setting of the scene have brought different changes, and the style displayed is also different. With the continuous update and adjustment of the 360-degree phantom imaging system and the concept of optical imaging, the main model of the museum can also be better displayed, scene modeling and even related needs. It is difficult to display the characteristics and appearance of the object itself, and the naked-eye 3D technology solves this problem very well. It can perfectly show its advantages in science and technology museums, museums and other scenes. The naked-eye 3D technology can also be applied in and education, indoor In terms of design and real estate development, it can specifically display the real three-dimensional effect of objects. In recent years, with the maturity of naked-eye 3D technology and the continuous improvement of software and hardware facilities, more and more advertisements use the form of naked-eye 3D. Glasses-free 3D (OPEN-3D) is also full of realism and three-dimensional sense, without the need to wear glasses. Such advantages have achieved excellent publicity effects. It has to be said that naked eye 3D will be an inevitable trend of future corporate publicity. Glasses-free 3D does not require any equipment (such as 3D glasses, helmets, etc.) to obtain a complete 3D stereoscopic image, which is easier and more convenient, and has a wide range of applications. In the field, you can see real objects from any angle. Information is particularly important, and most of the current images are tomographic images or three-dimensional reconstructed images.
Manufacturers who want to re-engage consumers' attention have developed a complete package. In stores, supermarkets, airports, corporate exhibition halls, specialty stores and other places, tailor-made suitable outdoor large-screen naked-eye 3D displays, content and interactive solutions for merchants, and display products and services in a three-dimensional and vivid manner, attracting the attention of the audience and increasing the desire to buy . With the continuous updating and adjustment of the 360-degree phantom imaging system and the concept of optical imaging, the naked-eye 3D technology can also be better displayed on the main model of the museum, and the scene modeling and even related needs can be achieved incisively and vividly. Coupled with beautiful music, the atmosphere and style displayed create a different atmosphere and bring a bright visual impact to the audience. With the help of the phantom imaging system, the outdoor large screen naked-eye 3D can not only make the screen more high-definition, but also realize the 3D stereoscopic reality for each exhibit with the digital application concept. Doctors are required to wear glasses and other additional devices, which reduces the convenience and comfort of observation compared with observing natural objects. In addition, the spatial size of the stereoscopic scene reconstructed based on the principle of binocular vision will vary with the observer, ranging from In principle, it is impossible to restore a stereoscopic image with the same size as the real object. Therefore, the above technologies have certain limitations for applications that require high imaging accuracy. With the development of technology, naked-eye 3D came into being. It has the advantages of being realistic, three-dimensional, and does not need to wear glasses. It is also loved by people and has a wide range of applications. Glasses-free 3D is often used in museums. , a place to display and study objects representing natural and human cultural heritage is also one of the areas where there is an urgent need for a new way of exhibition and display. Advertising has always been the main carrier for merchants' product promotion and information release in the market. However, nowadays, the saturation of screen coverage and the similarity of content have led to a significant decline in the audience rate of ordinary 2D advertisements. Manufacturers who want to re-attract consumers' attention have formulated A complete set of programs, in stores, supermarkets, airports, corporate showrooms.
In addition, with the continuous development and expansion of the market, outdoor large-screen naked-eye 3D will gradually be accepted by more and more enterprises and institutions. in people's lives.
