Facing 3D with VR or will usher in the best development opportunities from Baidu VR

In 3D, we don’t seem to be unfamiliar with the word. In real life, whether it is movies, games or videos are moving in the direction of 3D. When we are wearing 3D glasses at the cinema, we are surprised to watch one after another. In the 3D lens, the 3D stereoscopic picture gave us an immersive viewing experience. However, today's mainstream 3D stereoscopic display technology still can't allow us to get rid of the shackles of glasses and other auxiliary devices, and naked-eye 3D allows us to experience excellent 3D effects without using any auxiliary props.

Its technical principle is that when human eyes look at the same object, there is a distance of about 6 cm between the left eye and the right eye, and it produces two different images to send to the brain. In the 3D display, the left screen is input to the left eye, and the right screen is input to the right eye. The difference in the two eyes forms a feeling of a three-dimensional image in the brain. Because of binocular parallax, the objects we see have a sense of depth and space.

For a long time, because of the discomfort caused by wearing glasses, helmets, etc., the naked eye 3D technology cannot be applied to more scenes and is accepted by more people. Experiencing 3D technology for a long time will cause some experience people to produce Feelings of nausea, dizziness, and so on make many people feel uncomfortable about 3D technology and feel excited and worried.

As early as 1980, Nintendo developed the first commercially available 3D product, the 3D glasses, which can be used with CD players that hold FC game consoles. However, this project has not yet gone out of Japan and it ended in failure. Unconvinced Nintendo developed the Virtual Boy in 1995 and still supports 3D display, but it eventually failed. In 2011, Nintendo launched the world's first naked-eye 3D game console with face tracking - Nintendo 3DS. Its global sales reached 61 million units, and software sales exceeded 300 million, but its facial tracking technology is not very mature, slightly shaking or Movement affects 3D viewing.

The early naked eye 3D technology is not very mature either in terms of technology or content, and gimmicks are larger than practical ones. With the continuous development of technology, the current mainstream naked-eye 3D technologies include slit-type liquid crystal gratings, cylindrical prisms, and pointing light sources. However, they have more or less problems such as fixed viewpoint, dark brightness, narrow viewing angle, and dizziness. . Naked eye 3D has been invented until now for several decades, but it has not gotten a fire. In addition to its own technology is not perfect, the main reason is the lack of a good industrial atmosphere and ecological content.

As the saying goes, "Good horses have good saddles." The early naked eye 3D technology has no such intelligent operating platforms as Android, Apple, WP, etc. in terms of platform support. For a long time, electronic devices still stay At the functional appeal stage, it is difficult to bear the hardware requirements for naked eye 3D in terms of electronic components, screens, and hardware performance. The lack of performance and the lack of software underlying technologies restrict the development of naked eye 3D technology. In addition, many manufacturers only pay attention to hardware research and development, and ignore the establishment of the software content ecosystem, resulting in hardware upswing, but the content can not keep up, soft and hard inconsistent development, resulting in naked eye 3D technology once became a "deformed" development status.

Although the naked eye 3D is purely in various constraints and deficiencies, we cannot deny the advanced nature and future needs of this technology, and now the naked-eyed 3D industry is ushering in a period of high-speed golden development. From a national perspective, in the country's latest "13th Five-Year Plan" for the development of new display technologies, naked-eye 3D is characterized as "the most viable and will eventually become the next generation of display technology common platform for display technology", and Together with the laser display, it is regarded as the two key common technologies that were developed during the 13th Five-Year Plan. At the same time, planning also pointed out that naked eye 3D and VR, AR are not mutually substitute relationships, and they will jointly provide visual services to consumers with different preferences and different scenarios. With the support of national policies and technologies, naked eye 3D technology may usher in a new turning point.

From a corporate perspective, Chinese companies have gradually moved from "Made in China" to a new stage of "China's Ingenuity", which has obvious advantages in the industrialization of naked-eye 3D technology and the development of content applications. In domestic enterprises, at present, the screen transmission rate can reach over 85%, and the precision control can reach 0.5 μm, which effectively ensures the high quality of the image. There are also great progresses in the multi-viewpoint conversion algorithm and the human eye tracking algorithm. The product innovation brought about by the naked-eye 3D technology can also create new market and profit growth points for the company.

From the consumer's point of view, the general public's awareness of naked-eye 3D products has been significantly improved compared to the past. The use of naked-eye 3D technology in life scenes has improved people’s perception of what they already have and made the product move toward it. With the development of visual intelligence, it enhances human-computer interaction capabilities, making machines no longer a cold tool, and more often as a friend, which narrows the distance between products and consumers.

Although from all angles, naked eye 3D is a very dynamic sunrise industry, but in order to fully integrate the naked eye 3D technology into the consumer market, in addition to outside support, the “inside” also needs to be improved. The content of the support, consumers will be difficult to enjoy a complete 3D experience. Therefore, for enterprises, it is necessary to start with hardware and content. On the one hand, through hardware development, many 3D devices can enter the market; on the other hand, content development includes video, games, and applications.

Tsinghua University professor doctoral tutor, the National "Thousand Talents Program" selected Liao Hongen, using the naked eye 3D technology to create the world's first direct visual observation, more than 5 meters deep image stereoscopic display settings, to achieve minimally invasive surgery The three-dimensional space perspective navigation for medical treatment has created medical stereoscopic navigation, three-dimensional medical imaging, and advanced minimally invasive diagnosis and treatment integration system. At the same time, he also pointed out that naked-eye 3D technology is the first to begin with the medical industry, including the medical application of the first, but not limited to this medicine, we can even use other related fields, such as In areas such as education, entertainment, family, media, and industry, as long as it involves images, this naked-eye 3D technology can be promoted.

We have reason to believe that with the industrial upgrading and technological changes, naked eye 3D technology will be applied to more scenes, including games, video, medical, education, sports, shopping and other industries. People put forward new consumer demand for naked-eye 3D technology products, and also provide new reform ideas for industrial upgrading. In the future, naked-eye 3D will be used in more scenes. Through the Internet big data, naked-eye 3D will also launch a new “convergence” with the Internet. This has important implications for all walks of life. .
