In the fashion show “beautiful scenery” brought by Li Yuchun, he Sui, Zhang Zilin, Xi Mengyao and others, the stage is like a beautiful picture. It takes five minutes to lead the audience through the four seasons of the year. The graceful classical beauties in the Dunhuang desert slowly come, and the visual experience is also great.

In the shooting technique, there is also a “bullet time” surround panoramic shooting technique, which can freeze a picture and quickly switch the lens angle, so as to improve the visual experience.

Holographic projection is one of the highlights of the CCTV Spring Festival Gala. The most impressive scene is the performance of more than a dozen clone Li Yuchun.

As early as in the 2015 Spring Festival Gala, five Li Yuchun appeared in the song program Shu embroidery, which used holographic projection technology earlier. This technology enables the audience to directly see the three-dimensional virtual human without any glasses.

Perfect combination of sense of technology.

Related industry analysts said that from the perspective of the effect of holographic projection, it is still a problem

“Baby”, there is still a lot of room for development. With the development of this technology, we will be in more life scenes in the future, such as holographic projection parents chatting like real people, cloud drinking tea, cloud eating and so on.

In addition to arxr and holographic projection, artificial intelligence is also an indispensable element of the Spring Festival Gala.

In the previous two years of CCTV Spring Festival Gala, some robots have been shown. In this Spring Festival Gala, robots have developed from simple actions to more complex skills. For example, the robot cow that writes the word “Fu” is called “Fu”

Yumi is said to be the world’s first dual arm man-machine cooperative robot.

The calf robot that can dance in the program “get up the cow” is a new member of the Uber’s robot family, the “tuolanniu” quadruped robot. Like the cats and dogs at home, it can do a lot of very flexible movements.

2、 Black technology behind the cool stage of Spring Festival Gala

Due to the need of epidemic prevention and control, Andy Lau, Jay Chou and other actors were unable to perform on the scene this year, but they had great enthusiasm to participate in the performance, so the main station adopted Ultra HD

“Cloud” video technology, set up a bridge between the audience and actors.

On the spot of the Spring Festival Gala, “cloud” actors participate in the performance through videos recorded in advance and packaged by technology. This way is not a simple connection or plug-in, but as an integral part of the program, closely linked with the live actors.

Many people said that AR technology is really good, so Andy Lau was invited to the scene. How is this achieved? In short, there are four main steps:

1. The director of the program needs to compose the picture in advance and design the actor’s position and action in each frame.

2. A special team communicated with Andy Lau to record in advance in a large studio.

3. Hundreds of software engineers added a lot of image effects to the content of Andy Lau’s shooting, cooperated with Andy Lau’s singing and action, and added virtual content to realize “ar”.

4. Guan Xiaotong and Wang Yibo are real-time performances. If the content of the third step is superimposed with them, they will become “XR”.

At present, the cost of AR technology is relatively low. For example, lidar has been added to smart phones such as apple to achieve ar effect. But, XR

The technology application is relatively less, needs a lot of computing power, and the overall cost is relatively high.

In addition to cloud performance, cloud audience is also a new application of the Spring Festival Gala under the influence of the epidemic.

This year’s Spring Festival Gala stage is equipped with a huge ring-shaped new media background wall. 154 ultra high definition large screens are distributed above the back area of the audience. Each one has an independent channel, which can synchronously access 154 channels for presentation.

Relying on the development of 5g technology, “cloud” communication technology will realize the same stage interactive performance across time and space, and connect the auditorium on the screen with the live stage and auditorium to open up time and space.

From the specific operation point of view, this Spring Festival Gala combines panoramic free perspective shooting, interactive photography control, special shooting and real-time virtual rendering and other technical points, which brings the audience a breakthrough sensory experience.

And behind it, we rely more on hard core hardware facilities. For example, for martial arts programs in the Spring Festival Gala, CCTV and Huawei have deployed hundreds of 4K Ultra HD shooting equipment around the stage to obtain 360 degree video information of actors.

Then, in the Huawei mediacube device deployed on site, the organizer performs real-time rendering, integration, coding and other media processing on the hundreds of channels of UHD video streams collected, so as to output the wonderful content of 360 degree view conversion effect for live broadcast.

3、 In the post epidemic era, non-contact “cloud activities” have sprung up

The epidemic situation in 2020 has bred a new “non-contact” market. The Spring Festival Gala is a good case for us to see this market reflected in media events.

Chen Linchun, chief director of the 2021 Spring Festival Gala, said: “we are forced to use such a means due to the impact of the epidemic, but at the same time, we are forced to constantly embody our technical means in the Spring Festival Gala.”

In the post epidemic era, the market of “cloud activities” has become larger, which has also brought new business to media and visual technology providers. For example, CCTV network will build its dance beauty, video production, live support, interactive support and online exhibition hall

The “package” solution empowers all kinds of activities.

Taking the cloud China brand day 2020 held in May 2020 as an example, CCTV has created a brand

“Cloud Pavilion” and “cloud customization”. Using Shanghai Exhibition Center as the background, a pure virtual exhibition hall without relying on offline physical exhibition is built by the combination of graphics, video and special effects. As of 18:00 on May 15, the number of hits of “cloud brand Expo” has exceeded 7 million.

According to the comparison of the annual report of China’s exhibition industry in 2018 by Asia Pacific Exhibition Research Institute, more than 6000 exhibitions with an area of more than 2000 square meters, more than 800000 professional meetings with more than 50 people and more than 80000 festival activities with more than 10000 people will be suspended or not held from January to June 2020, which will directly affect the output value of more than 350 billion yuan.

Cloud activities have become a new trend, which will benefit the development of arxr, holographic vision, computer vision and other technologies.

Under this trend, technology giants have entered the market one after another. For example, in May 2020, Tencent released the all new cloud exhibition solution to build a new digital infrastructure for the exhibition industry through four dimensions: online exhibition assistance, supply and procurement docking, smart venues, and industrial interconnection. In June 2020, the Shanghai municipal government and Alibaba announced the construction

“Cloud exhibition platform” – cloud Exhibition Co., Ltd.

Of course, parties and exhibitions are just the tip of the iceberg in the whole non-contact “cloud activity” market. The demand of various scenes, including cloud new year’s greetings and cloud tea drinking, can trigger more imagination. With 2021

It is believed that many cloud application scenarios and requirements will continue to develop even if people’s normal activities resume.

Conclusion:

From the CCTV Spring Festival Gala, we can see a new cloud world. From the holographic projection, cloud performance, cloud audience, robot performance and other applications in the 2021 CCTV Spring Festival Gala, we find that machine vision, AI

And other technologies have become more and more popular.

In the post epidemic era of “non-contact” trend, cloud activities are creating new markets. This market urges sound visual images to break through the restrictions of online and offline, time and space, and is expected to push back

Arxr, artificial intelligence and other technologies.
