This afternoon, at the National Engineering Laboratory for Digital Television (Beijing), organized by the Administrative Committee of Zhongguancun Digital TV Industry Park, Beijing Peony Electronics Group Co., Ltd./Innovation Technology Platform and Beijing Peony Technology Incubator Co., Ltd., Beijing Peony The “Zhongguancun Digital TV Industrial Park Expert Forum and VR Salon†organized by the limited liability company and the Beijing SME Public Service Platform (terrestrial digital TV popularization and detection technology) was officially held. The forum invited Beijing Press, Publication, Radio and TV Bureau, CCTV, BTV, Zhongguancun Administrative Committee, Haidian District leaders, and Beijing Electronic Control Leaders to visit. VR Network (WeChat public number: VR platform) attended as the special media and gave speeches. . The forum was chaired by Zhao Peng, Marketing Director of Beijing Peony Optoelectronics Co., Ltd., Deputy Director of DTNEL / Secretary of the Union Ouyang Shuping gave a speech on the topic of "Relying on Radio and TV Development of the Internet of Things," and the Technical Center of Beiguang Science and Technology Group Zhang Dongsheng, the director, reported on the progress of the CCTV broadcasting coverage project of North Guangguang Technology. With the continuous development of society, information consumption has become an important area for stimulating the national economy. In the area of ​​LCD TVs and monitors, the SJ/T11343, 11348, and 11157 have been updated, and the GB/T26683 to 26686 series of terrestrial national standard digital TV receivers have released the 2017 version of the general specifications and measurement methods for digital television receivers, digital TV chips, and terminals. The manufacturing industry once again ushered in new challenges. In this regard, Territor Inspection Deputy Director Li Qiang and Director of Peony Optoelectronics Zhao Peng on the "New Display Line Standard SJ/T11343, 11348, 11157 <TV Receiver Part II: Sound Channel Electrical Performance Test> Standards" The "New Generation of WiFi Standard 802.11ac Test and IOT Test" was interpreted. In order to gain insights into the latest technologies in 3D/4K and HDR TV testing, Beijing Jialong Lieda (a company registered in Japan by Lida Electronics Co., Ltd.) Wu Xingwei also introduced the 4K and HDR detection solutions for the visitors. The president of China Unicom’s Yi Cheng introduced the MDO hybrid domain testing technology. The application fields of new display technologies are continuously expanding. Large-screen, 4K, HDR high dynamic range displays, and VR/AR products are constantly challenging the limits of consumers' visual experience, setting off a new round of upsurge. To further understand the latest developments in virtual reality, the expert forum invited VR's famous enterprise, Qidi Virtual Reality (Beijing) Technology Development Co., Ltd., to participate in the event. Liu Bo, an onsite VR operation manager, told the audience about “The Frontier of Virtual Reality Technology – Eye Tracking and The theme of gaze point rendering is analyzed in detail. Liu Bo first explained what eye tracking technology is for. The process of extracting the gaze direction of the human eye through infrared scanning and measuring the gaze point is a technique that helps researchers understand visual attention. Through eye tracking, it is possible to detect where the user is watching at a certain time, how long the gaze is, and the trajectory of the eye movement. Eye tracking technology can solve the pain points of VR head display and AR glasses with high price and high power consumption. Through eye tracking, the position of the eyeball of the user is determined, so that the VR/AR head can better adjust the picture parameters and provide the user with the best comfort. It can be seen that the eye tracking technology will firstly improve the head-mounted comfort and ease of use, and at the same time require the user to be able to interpret the gaze point of the user at high speed and effectively. Through comparative analysis of eye tracking kernel parameters, it can be known that eye tracking technology has the characteristics of fast algorithm, low latency, low CPU share, high frame rate, and compatibility with various operating platforms. The gaze point rendering technique derived from eye tracking, also known as the retina center rendering technique. The clarity of the place where the user is watching is 100%, and the clarity of other places is lower. This technology has great significance for VR. VR technology is clearly rendered globally, and the computer will render all scenes clearly for users to watch. A large part of the clear pixels are wasted during the process. This kind of global rendering brings a lot of pressure to computer computing. Users need to have very high-performance graphics cards to get a good picture. The gaze point rendering technology allows the system to clearly render the image of the eye focus center. The image of the gaze point attachment is blurry layer by layer, which reduces the load of the graphics card and the CPU and the GPU, saves the computing resources, and enables the middle or low configuration computer or machine. You can also get high-quality hardware to render the image. 1. The premise of gaze point rendering technology is to be able to quickly and effectively interpret the user's fixations and effectively analyze user intent. 2. Eye tracking and gaze point rendering techniques derived from eye tracking. It can optimize image rendering, reduce the CPU and GPU computing load, make the ordinary computer can get ultra-high configuration computer to render VR and other image effects, and has an important role in promoting the civilianization and parity of VR/AR hardware. (Application areas for eye tracking and gaze point rendering) In addition, Wang Hongyan, director of the Peony VR/AR Engineering Laboratory, also spoke on Peony's VR panorama solution. Wang Hongyan explained to everyone that the general speaking of panoramic video shooting is an acquisition and production process. At the forum, Wang Hongyan showed common panoramic photography equipment on the market and introduced the production process of panoramic video shooting. 1. In the early stage of panoramic shooting, the production team communicates with the customer, selects the appropriate camera for the scene according to the customer demand, assembles the necessary accessories, and adjusts the parameters. 2. Set the script and details of the shooting contents according to the customer's needs. Professional shooting according to a specific script. 3. After the shooting is completed, the process of the panoramic video is completed by editing, splicing and stitching, image processing, and adding special effects. (Panorama Live System) Panoramic video can be applied to live conferences, scenic tours, interactive teaching, sports events, etc. Wang Hongyan also brought the Peony Panoramic Live Broadcasting Solution to various indoor and outdoor scenes such as education and teaching, outdoor live broadcasting, theater concerts, and news media. (AR implementation process) In addition, Wang Hongyan also gave a speech on AR. The AR system has three prominent features: 1. Real-world and virtual information integration; 2. With real-time interactivity; 3. Adding and positioning virtual objects in the three-dimensional space. The VR/AR industry experienced a period of technological accumulation, an outbreak period and the current recession period. Wang Hongyan expressed his thoughts on the development of the industry and expressed the hope that the VR industry chain will be further improved. It said: The development and progress of technology fundamentally addresses the collaborative capabilities between people and machines, people and people.
