At the 2017 Spring Festival Gala which was just over, the first time through the CCTV AV client, the live broadcast of the VR system will allow audiences thousands of miles away to feel at home in the venue. At the same time, major TV stations have begun to integrate VR/AR technology. For example, Jiangsu Satellite TV adopts a holographic VR live-view screen to integrate holographic projection technology and AR technology into programs and stage sets. As long as the audience wears VR glasses, they can watch the whole party in 360 degree panorama; Hunan Satellite TV uses the combination of water curtain and technology to create a fantasy water stage, introducing AR surreal technology, allowing the audience to experience the thrill of virtual reality at one go.
VR is a new revolution in an interactive way. People are realizing the transition from interface to space. This kind of interaction emphasizes immersion, and users want to be fully immersed and truly “enter†the virtual world, motion capture technology. Is the key invisible key in the VR industry.
Motion Capture Technology, the Invisible Key to VR World
Motion capture technology, abstractly speaking, is a system that captures your entire body movements and even facial expressions. Through mathematical calculations, it restores and rebuilds a virtual character of a three-dimensional model, and this three-dimensional virtual character changes with your movements. . It is to copy the human actions in reality to the computer-created virtual characters. However, it is simple to say, but to capture the various actions that are captured at any time and at all times, there are many technical problems.
Currently there are two main motion capture technologies: optical motion capture and inertia-based motion capture.
Optical motion capture relies on a complete set of sophisticated and sophisticated optical cameras. It uses computer vision principles to capture the whole body's motion by tracking multiple target high-speed cameras from different angles. Most of the large-scale productions in the United States are based on this optical motion capture technology.
The inertial motion capture system captures motion by Sensors, and then builds a three-dimensional model through data transmission and data processing. A complete system usually includes dozens of sensor units, each of which includes a gyroscope, an accelerometer, a magnetic sensor, and a digital signal processor.
In addition, acoustic motion capture technology based on sound localization is relatively still in the experimental stage, and is still not mature compared with the optical and inertial motion capture technology.
The optical-based motion capture scheme has high accuracy and does not require wearing complicated peripheral devices. However, due to the need to build various cameras for capturing motion, the cost of these cameras is high, making the cost of optical motion capture programs always high. No less, it becomes a major obstacle to universalization.
At last month’s CES 2017, local Chinese company Realis (RuiLi) displayed its own optical motion capture system (RTS optical motion capture device) with independent intellectual property rights, which is accurate and stable. It has been verified and obtained a number of international patents for inventions. The technical parameters have reached the international minimum level with a minimum delay of 5.5ms and submillimeter-level errors. The quality of the products has surpassed that of similar top-level capture devices in the United States and Japan. What surprises the industry and developers is that Rui Li as the RTS capture VR integrated system makes the cost of VR technology will be reduced by more than 70% compared to the current stage, greatly promote the process of VR large space free interactive program layout.
Rui Li as RTS optical motion capture system, from the optical, lens, driver, product appearance and structural design and other aspects, real-time smooth motion capture, provide stable and accurate target tracking, for multi-user instant interactive, mutual warfare, mutual aid game Provides a satisfactory solution. At the same time provide hundreds of reflective ball image analysis and tracking target, with simple, fast, and intuitive operating methods for the user to solve the whole body action and virtual scene interaction, so as to achieve intuitive firearms or weapons Daguai operation of multiplayer interactive battle VR Experience.
The technology leadership is said to be broken, and the experience is not as true. The VR combined with optical motion capture technology will open the door to the new world of virtual reality. As for the previous Spring Festival Evening VR broadcast, the use of mobile phone APP + mobile VR glasses or VR integrated machine to present the effect of virtual reality, and regardless of the quality of the effect, it is difficult to achieve the level of expectation in the sense of immersion, because At this time, the experiencer is more in the perspective of a “peeperâ€: wearing a VR head and changing the field of view by turning his head.
The most significant change in the VR experience brought by the optical motion capture technology is that the system will synchronously know the attitude and body movements of the experiencer, and feedback in the virtual reality world. Also, in the VR live broadcast, the experiencer will be able to Very natural body movements, let yourself walk to the middle of the big stage of the Spring Festival Evening, or stand beside Dong Qing, feel the focus of the eye-catching experience of the people, when happy, dance with the dancers, or come to the stage, To pay homage to the 100-year-old Red Army, at this moment, lose all kinds of operating handles and buttons, and the most natural stretch action can be brought into the virtual reality with the support of the optical motion capture technology and show it. The kind of people people have pursued for thousands of years in the paintings have been beautifully painted.
The door to a new world has opened up, omnipotent VR era
Since the VR concept was lighted in 2014, VR has become the most popular application in various industries. Faye Wong's “Wing Music One†concert, as the first product in the domestic performing arts market that uses VR live streaming, is regarded as another milestone in the VR broadcast industry.
In the movie industry, the pursuit of virtual reality has always existed. The appearance of "Avatar" in 2009 has enabled people to experience the powerful visual experience brought by the three-dimensional world in the cinema. The emergence of VR motion capture further enhances the audiovisual experience. As long as the device is equipped with a VR device, the viewer can truly experience the entire film environment. Through the rotation of the head, you can see the real scenes around you. The experience in the cinema, and there is no cinema time limit, you can watch movies anytime, anywhere.
For game enthusiasts, VR motion capture will allow players to break through the virtual fourth wall and use motion capture technology to give players a truly immersive experience. Whether it is role-playing, racing racing or action games, VR motion capture can provide an experience that is almost identical to the real environment.
With VR motion capture, people can create a virtual human model. With the help of trackballs, HMDs, and sensory gloves, they learn to understand the structure of various internal organs of the human body and perform operations on virtual human models. After observing the effects of surgery, they can also use VR. Motion capture technology trains new doctors.
Combining VR motion capture with the most popular live broadcast, each viewer can face face to face with the host in a virtual environment, and can directly talk with the anchor, completely subverting the previous live broadcast mode.
VR social networking is an indispensable and important part. With the help of motion capture technology, VR unique unique immersive experience and social perfect combination to create a virtual reality world, players can experience comparable reality VR social .
Conclusion:
Starting from the mathematicalization of human inventions, the virtualization trend of the physical world has continued for thousands of years. The development of computer IT technology has promoted the trend of data flow after virtualization, and the re-consolidation of the digital world in the physical world will become a new technology. The key part of the revolution, virtual reality technology will also play a very key role in this field. In the digital era of the future, virtual reality is likely to be more than just the exclusive player of the loyalty player, but the next generation of platforms following PCs and mobile phones. It will use the human-computer interaction performance of the Matrix style to transform the entire human science and technology. Development brings a new ladder.
