On September 28th, Pirates of Dream Geek held an open class at Nanjing University of Information Technology with the theme of “Virtual Reality (VR) Industry Status, Development Trends, and Technology Applicationsâ€. The event was organized by: School of Computer and Software, Nanjing University of Information Technology , co-organized by Pirates of Dreams Geek, Multi-Fire Studio and the Institute of Science and Technology, this event invited Hypereal graphic technology director Li Hui, Nibiru technical director of the University Division Zhang Yuanqiang, domestic famous VR product evaluation division pencil and Pirates of the Dream Gee VR experience division An Di as the guest speaker. This open class will promote VR to college students, popularize VR knowledge, and stimulate students' enthusiasm for VR. Explain the current and future development of VR, let more people understand VR, know VR. It is hoped that this will promote the development of schools in VR education, R&D and other related fields.
At the open class site, Hypereal provided two camera sets and three camera set experiences, as well as two friends of the big friends for the guests, teachers, and students. Before the public class began, the students who came to experience the equipment were in a constant stream and showed up. VR's curiosity, excitement, and surprises have given VR a preliminary understanding of the experience.
At 3:45, the open class was opened with MR painting. MR displayed the charm of space painting and the immersive space painting experience. After that, the first guest speaker was a dream geek and brother with “real dreamâ€. - The entrance to the next world?
An Di introduced the virtual reality technology to his classmates with his early VR equipment. From his VR experience, he introduced the current mobile VR, all-in-one, host PC, and three types of VR devices, and briefly introduced the current market. The mainstream VR device. Then Andi started with the application of VR, focusing on the VR education field, VR version of the physical and chemical laboratory, VR version of the clinical medical operations and other projects, will better impart knowledge to students and society. Afterwards, An Di introduced the VR design, from a panoramic picture to a virtual scene created to make people feel the VR's new record and transmission form. Finally Andi introduced the Pirates’ Dream geek community.
The second guest speaker, Zhang Yuanqiang, the technical director of the Nibiru University Division, gave a speech on the theme of “VR Technology in Education Industry Applicationâ€. He explained the three aspects of VR industry appeal, VR industry policy, VR technology and education, and introduced VR. The future development trend, talent development direction and demand. In the speech, it was mentioned that the country is speeding up the construction of educational information infrastructure, promoting the modernization of educational content, teaching methods and methods, and the virtual simulation experiment has become a demonstration teaching project. Finally, in several cases, the application and significance of the combination of VR technology and education were introduced.
The third guest speaker of the famous domestic VR product reviewer pencil delivered a lecture with the theme of “What kind of VR is an opportunity?â€. It was a lively atmosphere, with four kinds of specific sounds, texts, pictures, and videos. The information delivery vehicle introduces the essence of VR as a new form of information delivery vehicle. Then he put forward the problem of VR video narrative and couldn't shoot with traditional narratives. At this time, he pointed out that this is the current opportunity for VR - "opening up the school, the future trend". It can create a form of VR, plus VR. It is a great opportunity for people to obtain information mainstream carriers in the future.
The last guest speaker, Hypereal Graphic Technology Director Li Hui, took the theme of “Hypereal Positioning Black Technology†and described the position tracking system of Hypereal Pano using autonomous technology. It mainly talks about PNP in the positioning workflow, through the basic model. - Principles, basic model - camera internal reference, basic model - imaging Three aspects of the basic principles of positioning are introduced. Then the PNP problem and the way to solve PNP are explained. Finally, Li Hui emphasizes that PNP is only one part of the positioning process. In fact, there is no black technology. Any good features and products are step by step.
After the four guests finished their speeches, Andi chose to take questions from the forum students and answer them. The storm mirror daydream package was sent as a prize, followed by a round table meeting. The guests started business in VR field, VR education application industry, positioning technology and Basic knowledge of VR needs to be answered and explained. Finally, the students were asked questions freely, the students actively asked questions, and questions about VR experience, education, and application were answered one by one. After the lucky draw session, the storm mirror daydreaming set prizes were drawn out and the event was successfully completed.
Pay attention to the VR Net official WeChat public number "VR platform" to get more VR/AR industry fresh information.
CWDM - Coarse Wavelength Division Multiplex
CCWDM is Compact CWDM (Compact Coarse Wavelength Division Multiplexing), a wavelength division multiplexing technology based on TFF (Thin Film Filter). It works in the same way as CWDM modules, except that CCWDM uses free space technology. , compared with the common CWDM optical fiber cascading method , the CCWDM package size is greatly reduced compared with CWDM modules, and the insertion loss is lower and the consistency is better; it can replace CWDM Products are used in telecommunications, enterprise networks, PON networks, cable television and other fields. The lower insertion loss enables the CCWDM module to have lower signal attenuation during use, thereby reducing the power requirements of the signal transmitter.
For the CWDM module, limited by the minimum bending radius of the optical fiber line, the size of the packaging box cannot be made too small, resulting in most of the space in the box being idle. The adjacent channels of CCWDM use parallel beams to cascade in free space instead of optical fibers. Without the optical fiber used for cascading, the size of the CCWDM packaging box can be greatly reduced. For example, the size of the common standard 4CH CWDM is 80×60×12 mm, and the size of the CCWDM module of Yiyuantong is 50×27×7.7mm, which is only 1/4 of the standard CWDM package size. Can be widely used in high-density environments.
