In recent years, with the rapid development of 5G, the "wind of smart phone revolution" blown by 3D has gradually become stronger and show great development potential. For example, in July this year, RED released a HydrogenOne smartphone with a holographic screen. HydrogenOne is equipped with a 5.7-inch holographic display screen. Through unique functions and algorithms, it can seamlessly switch between traditional 2D, 3D and holographic content. Users can watch 3D holographic images without wearing a helmet and special glasses; In August, Sony also released its flagship mobile phone Xperia XZ1, which not only improved the camera effect, but also added a 3D scanning function to the mobile phone; Apple’s newly released iPhone X has 3D original depth structured light scanning imaging technology that makes 3D data collection difficult. Limited to large, expensive and bulky equipment, the 3D scanning reconstruction model becomes something that everyone can operate.
In pursuit of the 3D trend, domestic mobile phone brands have never been left behind. At the recent V10 product launch conference of Honor, Huawei Honor President Zhao Ming announced Huawei's 3D structured light technology. This technology supports 3D face modeling and face recognition, can reach sub-millimeter modeling accuracy, supports 300,000 point cloud 10s reconstruction, supports payment security level recognition, and 400ms fast unlocking. It also supports 3D facial expression control and 3D small object modeling. When modeling small 3D objects, it can achieve sub-millimeter accuracy, with smart background removal, and gorgeous texture reproduction functions.
In addition, the development of ivvi mobile phones in the field of 3D computing vision in recent years has also attracted the attention of the industry. Public information shows that Shenzhen Super Duowei Group, the parent company of ivvi mobile phone, was established in 2004. It is a technology-driven company engaged in the research and development of computing vision. It has a complete patent layout covering the entire industry chain of key computing vision technologies. So far, it has been worldwide. More than 1,000 patents have been applied for, and more than 82% are invention patents. Among them, the number of patents for 3D display technology ranks first in China and second in the world. In 2013, the ultra-multidimensional tracking glasses-free 3D display technology won the "First Prize of China's National Technology Invention". In December 2016, Super Duowei completed the acquisition of ivvi mobile phones.
As early as April this year, ivvi mobile phone launched its first smart 3D mobile phone ivviK5. The machine uses a special ultra-multidimensional high-definition naked-eye 3D special display, equipped with a human eye tracking camera, and a built-in ultra-multidimensional 3D visual motion chip, which is equipped with a "discrete graphics card" for the mobile phone. Compared with products of the same generation, the 3D display effect of ivviK5 has obvious advantages such as a more three-dimensional picture, wider vision, high brightness, and no dizziness. It is reported that the 3D display effect of ivviK5 was praised by two industry professors, Li Jinliang and Ding Shouqian at this Global Intelligence World Conference.
Challenges faced in the development of 3D smart terminals
After more than 40 years of development, China Mobile has experienced 5 generations of "replacement between old and new". In this historical process, 3D has also been used as a breakthrough direction for some smartphone manufacturers. However, after several ups and downs of development, 3D finally did not set off a huge wave of smart terminal market changes. Earlier 3D display products were often criticized by consumers due to limited technology and viewing angles.
"There are five important steps in the transmission of information, namely, the acquisition, transmission, storage, processing and display of information. With the development of 5G, if we want 3D information to enter thousands of households, we also need to solve the problem of information acquisition and information Show these two weak links." Professor Li Jinliang expressed his views on the current problems in the development of 5G+3D.
In this regard, various smart phone manufacturers are also making continuous efforts for the integration of 3D technology and smart terminals. Compared with the previous generation of 3D mobile phone products, today's products have greatly improved their 3D information acquisition capabilities and 3D display effects. For example, XperiaXZ1 uses Sony BRAVIATV technology, combined with HDR (high dynamic) technology in the screen, watching movies or videos can bring better color and contrast. In addition, XperiaXZ1 has TRILUMINOS mobile display technology, X-Reality mobile image engine technology and dynamic contrast enhancement. A variety of technologies are combined to enhance the screen effect; Honor V10 is equipped with 3D structured light lens technology, which supports 3D face modeling and face recognition, and has reached the security level required by mobile payment. It is reported that users can scan their own face data through a lens with 3D depth scanning, and the cloud algorithm performs deformation and reconstruction, and users can see their three-dimensional images on the mobile phone in real time. Through manual debugging, users can perform 3D beautification, 3D fittings according to their own preferences, and perform performances and facial expression sharing with their own set images.
In addition, ivvi mobile phone has also stepped up its R&D and strategic layout in this area. It is understood that in April this year, ivvi realized the layout of the three major areas of 3D display, independent GPU and face recognition eye tracking through K5, which not only greatly improved the 3D display effect of smart phones, but also innovated the way of human-computer interaction. Recently, Super Multidimensional Group and ivvi mobile phone specially established a 3D interaction department, aiming to accelerate the implementation of technical research results in the field of 3D computing vision, design and improve product functions from the perspective of user experience, and provide users with new, more convenient and interesting 3D interaction methods . In the future, ivvi mobile phones will rely on the parent company's leading technology in 3D and computational vision, with image recognition, intelligent 3D, computational vision, etc. as breakthroughs, and focus on the layout and development of 3D computational vision, AI, AR and other fields.
At present, countries around the world have made a lot of investment in technical feasibility studies, standardization, and product development for future 5G mobile communication networks. The development of 5G needs to be coordinated on a global scale under a unified framework. At the same time, in the 5G communication system, continuous research and innovation such as large-scale multi-antenna and channel modeling can not only effectively improve the efficiency of wireless spectrum utilization, but also accelerate the wireless data transmission rate and support the access of more terminals. In order to cope with the rapid development of the information society in the future, the network should have intelligent self-sensing and self-adjusting capabilities. The research of C-RAN, D2D and other technologies is precisely for this purpose, and the high degree of flexibility will also become the future 5G One of the essential characteristics of the network. At the same time, green energy saving will also become an important direction for the development of 5G, and the function of the network will no longer be at the cost of a large amount of energy consumption to realize the sustainable development of wireless mobile communications.
In the next 10 years, mobile communications will undergo earth-shaking changes. At present, 4G has just been deployed and will continue to be commercially available for a long time. As a new generation of mobile communication technology for industrial development after 2020, 5G has an important impact on improving large bandwidth, solving the interconnection of everything, and achieving more reliable and lower-latency communications. In 2016, 5G technology has further developed. 3GPP has already begun pre-research on 5G standards in 2016, and follow-up 5G technical solution solicitation and standardization work will also be carried out in full swing.
5G is a converged network, but also a more complex and dense network. The support of 5G far exceeds the scenarios, data volume, and device access that 3G and 4G networks meet. The realization of this network requires continuous development and innovation of technology. In addition, 5G will also pay more attention to user experience in all aspects, and will be deployed intelligently according to the individual needs of different users, so that users can easily and quickly access it at any time and anywhere. At the same time, the future of 5G technology lies not only in the further improvement of data transmission speed, but also in that it is an extension of human capabilities. All surrounding objects are in a real-time networked state and can perceive and interact with each other.
Combining with the development and application of 5G key wireless transmission technology, we will clarify the key technology of 5G mobile communication technology and promote the substantive development of 5G technology.
5G solves the problem of ultra-high-speed data transmission and lays the foundation for realizing the interconnection of everything, 3D rendering and other scenarios. The transition from two-dimensional to three-dimensional information display is an inevitable trend. According to this trend, the 3D industry will usher in a new round of growth with the advent of the 5G era. As the mobile phone market is stuck in the dilemma of homogeneity and lack of innovation, 3D display and applications based on computational vision and AI/AR technology will become the next innovation force for smartphones.
