On July 6th, at the main venue of the Zero-Tech Festival, Professor Sang Xinzhu presented the 'Naked Eye 3D Light Field Display Equipment' on behalf of the National Key Laboratory of Information Photonics and Optical Communications of Beijing University of Posts and Telecommunications. This technology not only does not require 3D glasses. Helmets and other equipment as an aid, its display effect and authenticity is also much higher than the naked-eye 3D equipment we have been exposed to before.
The naked-eye 3D technology has been mentioned in recent years, but its technology is not mature. Like the previous HTC EVO 3D mobile phones, most of them use a lenticular lens display panel to refract two parts of the image into the user's eyes. The two eyes synthesize images with stereoscopic effects. The disadvantage is that not only the 3D effect is general, but also there are certain disadvantages in terms of material, viewing angle, picture brightness and so on.
In the large-scale naked-eye 3D display field, the use of water curtains and other media to reduce the diffuse reflection of objects in the actual environment is also affected by resolution, stability, etc., and Professor Sang Xinzhu shows The naked-eye 3D technology starts from the pre-completed light field simulation, so that the light carrying the light information is ingested into the human eye according to the calculated direction and angle, and finally the countless light gathers the stereo image.
After the keynote speech, we were fortunate to interview Professor Sang Xinzhu. The professor answered our doubts about various issues such as products, industry and college research.
Products: Leading technology, wide range of applications
The first is the mobile phone field that we are most concerned about. Professor Sang Xinzhu mentioned in the keynote speech that there have been related discussions with Huawei. We also consulted about this. Professor Sang Xinzhu said that he is more inclined to create mobile phone peripherals. To realize the light field 3D mobile phone, the mode considered is that the mobile phone itself is input, the content is on the mobile phone side, and the original design of the mobile phone is not changed, and a simple peripheral is made.
As for the cinema, as an application scenario with strong demand for 3D experience, there has been a preliminary discussion. Professor Sang Xinzhu believes that most of the existing 3D products on the market do not conform to the human visual characteristics, and the light efficiency is poor. 3. In the process of recycling 3D glasses, eye health problems are also difficult to guarantee.
He revealed: 'We are now slowly making a trial theater in Beijing, because the theater wants to do the kind of giant screen, very large, 18 meters wide, 11 meters high. In fact, there is no problem in the display principle, it is craft It is difficult to integrate with the final assembly. Also consider the original speaker device, because like the current 3D theater, the sound comes out from the back of the screen, and the screen replacement should also consider changing the layout of the speaker, so it is better to build a new theater. '
In addition, Professor Sang Xinzhu predicts that exhibitions and education are also two markets with great potential, and can do a lot of related combinations. 'Especially museums, they have a lot of cultural relics, and many have realized 3D digitization, and everyone visits the real effect. It's not very ideal. If you can show it in the air and interact with it, you can even cut it out and see it, which is better than the real experience.
In the field of education, the naked-eye 3D light field display technology also has advantages in terms of viewing distance, angle, etc. 'We are close to the viewing distance, that is, the 3D image is close to you, far away, just like the real object is far away from you.' The professor said that the professor believes that the introduction of naked-eye 3D can effectively improve children's interest in the education of primary and secondary schools. The current school is not without demand, but there is no perfect product on the market.
Transformation of results: University-based research, social responsibility-oriented
Not only is it a leading research institution in the industry, but also has close cooperation with upstream and downstream industries. At the same time, there are many companies and capitals interested in investing. It is supposed to have good commercial conditions, but Professor Sang is cautious in scoring this performance, he said. : 'We have done more in the past few years in solving the needs of the industry or the country. Because we are not the same as the startup company, we are a university research institution with more social responsibilities, not profit driven.'
In the process of scientific research, in addition to the orientation of social responsibility, the reason why Beiyou Optical Laboratory can maintain a high degree of autonomy comes from many factors, including the natural drainage of projects and funds brought by advanced technology. Professor Sang Xinzhu gave us an example. 'In fact, we feel that some capitals are inconsistent with your ideas and ideas, and they are very passive. So we want to do our own characteristics. There are also many companies that cooperate with us. We didn't take the initiative to sell the equipment, but some units saw the demand afterwards, and we also provided some '.
At the same time, for the transformation of results, Professor Sang Xinzhu believes that there are also differences in different fields: 'There are some rigid needs, such as military, aerospace. Actually, we are not doing civil visual improvement, although this aspect Very large, but most are not rigid requirements, and there is no difference between the main visual experience. However, in the industrial field and other industrial applications, the efficiency is greatly improved, such as military and aerospace applications, which reflects The role of scientific research'.
In the civil-related field, Professor Sang Xinzhu said that the current cooperation is more in the form of projects, providing solutions or actual products for the needs of enterprises. 'We do naked-eye 3D cooperation with Minkou, we are doing some solutions. Cooperation in the research of new products and new technologies is done in the form of projects and cooperation with enterprises.
Being able to do this is easy, and it has nothing to do with the identity of its highly efficient research institute. Professor Sang Xinzhu said frankly: 'We have a lot to do with the support of the upstream and downstream. Our team has a tradition of doing industry, showing The holographic application industry is basically promoted by Professor Xu Daxiong, the founder of our team. We have good cooperation with upstream and downstream companies including two listed companies. When we need some special processing equipment, like BOE and Many companies in Shenzhen have given great support and customized the special components for us.
Industry development: Let each technology reflect its value when it works
On the issue of the naked-eye 3D popularity time and the trend of technology development such as VR/AR, Professor Sang Xinzhu said the words in our subtitle: 'Let every technology go where it works. Reflecting its value, this makes more sense. '
Professor Sang Xinzhu replied: 'In fact, every technology has its own purpose. Like VR, it may be better to be immersed. I am completely in the virtual scene. AR is virtual and real. It is essentially Speaking is a scene of personal application, but now the experience is not very good due to the limitations of technology itself. The naked eye 3D provides an application scenario with a group experience, including Huawei's previous discussions with us, to do remote meetings. Now, the video phone does not have the kind of intimacy, the sense of presence. We have done the naked eye 3D, then your sense of proximity will be there, so the social relationship between people is actually obtained in the case of naked-eye 3D viewing. The reservation, on the basis of doing virtual or visual enhancement, is that it is more suitable for mass discussion scenarios'
Because of the limited time, Professor Sang Xinzhu could not tell us more details, but in the dialogue, we can feel the scientific research model that is not driven by profit but can maintain its healthy and hematopoietic. The road to innovation in other colleges and universities.
Different from the strong profit-making purpose of science and technology enterprises in product conversion, the State Key Laboratory of Photonics and Optical Communication of Beiyou Information has taken on more social responsibilities, which makes the university word worthy of its name. This is also a kind of function. In the occasion to reflect the performance of its value, we also hope to see more such a responsible university and research institutions can appear in our sight.
