NTT DOCOMO starts commercial services in the spring of 2020, which uses the latest technologies such as 5G, AI, and IoT, "Docomo Open House 2020", January 23, 2020.It was held at Tokyo Big Sight.The technical exhibition started in 2009 at the company's R & D base in Kanagawa Prefecture, and is held every year.The scale has become larger year by year, and in recent years it has been a large exhibition that shows technologies and business solutions using the exhibition hall of Tokyo Big Sight.
In particular, this year, the exhibition of 5G service experiences, which started in the spring of 2020, was excited.Here are some of the most noticeable video -related use from the exhibition hall.
The music live event was shot with two Astro-designed 8K cameras "CM-9010-B" and distributed at 5G.I was able to experience the situation at 3DVR at the booth
The "3DVR Live Video Distribution/Watching System" is a demonstration experiment/POC stage system that can be enjoyed in VR, with music live videos taken with 8K cameras in real time.You can live music live and sporting events live on 3DVR, where you can enjoy a realistic video and sound as if you are in the live venue wherever you are.
In October 2019, a demonstration experiment using the system was conducted at the Tokai TV Furusato Festival 2019 at Hisaya Odori Park in Sakae -ku, Nagoya,The sound is taken on a stand, and the sound is made of three -dimensional sound recorded in the Yamaha developed Vireal microphone.
At the booth at the exhibition hall, when I actually experienced the system with a VR goggle vive pro, I was able to shake my head and look around the stage around 180 °.It was very real, especially at the live venue, especially the male idol approaching here.
With this system, the event held in Nagoya and Osaka will be distributed in real time in real time in the future, and a real VR experience as if you were in Tokyo while in Tokyo.
Another version that distributes wide video live.Even with the naked eye, video distribution with a sense of presence like VR is possible
In the corner, a system that used three 4K cameras taken using a 8K camera was introduced in real time and distributed a video equivalent to 10K.The system is the same as the 8K live distribution system, and it is a wide video version of the same system.
It looks like a player is moving on the board game
"Top Top 3D Professional" is a 3D project of a dedicated housing that reflects the 3D projector video using a mirror and projected on a plane.If you look into the video from the shooting position through the shutter glasses system, you can watch the relay video in 3D.Using two 4K cameras, it is realized by shooting like a giant's eyes, leaving the left and right distance several meters away.
If you actually look at it, it is interesting to see the realism that cannot be tasted on a flat display.In particular, you can see the game with a bird's -eye view, so you can see the situation of the game at a glance.It looks interesting to use it for tactics.
VR modeling by Gravity Sketch.It is possible to work with multi -users using 5G
The "3D Design Solution" is designed by designers in multiple bases in one VR space.According to the booth staff, it is ideal to be able to design 3D things in recent design sites, and some have shifted in the direction of design and drawing in the VR3D space.At the booth, a demonstration using the design platform "GRAVITY SKETCH" that realizes an environment where you can create, collaborate, and review in 3D.
The feature of this demo is the realization of multi -users.In the future, designers in remote areas can share the same screen using the 5G features of small delays and large capacity move smoothly.Finish the same thing while sharing the fields you are good at.It is said that it can speed up and improve quality.
The spatial imaging Iris surface -type screen is that you can enjoy 3D images from anywhere with naked eyes without wearing 3D glasses.If you look inside as if you looked into the well, you can enjoy the content with a thick image.At the same time, the feature is that you can enjoy content with a large number of people.
The light projected from the projector reflects on the screen, and is located on a space where the screen is located.As a result, the Iris side of the projector is binding to the air, and the observer can only see the projected video within this range.
The great thing about this screen is that 60 projectors are used to make the video arranged in a circle.However, this technology had to place a projector narrower than the distance between the eyes, and initially needed 300 projectors.Therefore, it was possible to achieve 60 units by blurring the video so that the images adjacent to the images and the image are easily overlapped.
The 60 projectors have a built -in microcomputer to put out each video.It is said to be realized by projecting a video of resolution less than HD.
The entered video is switched in the cloud.The state of the demonstration is not possible, so the photo is only a bulletin board.
Virtual Production allows you to handle live videos and distribution with multiple cameras and web browsers alone, such as sports and band live events.At the exhibition booth, there were two cameras connected to the Internet and two smartphones, a total of four cameras, and demonstrated that four cameras were switched by cloud and distributing them.
The feature is that it does not need a physical hardware switcher.The necessary functions are on the DOCOMO Open Innovation Cloud, the collaborative platform, and if there is one laptop that can be connected via the Internet, you can switch camera images from the web browser anywhere.It is said that it is not a characteristic of low delay, but it can be used easily, low cost, and easy to use.
Shoot the surfing tournament with 8K cam coder 8C-B60A.Real -time HD cutting out by Tamazoneworkstation
This is a demonstration of the concept/research stage that cuts the necessary parts and scenes from 8K videos.At the booth, the surfing tournament was shot at 8K.It is to cut out the necessary parts and scenes from 8K videos.It is possible to detect people using AI, and can cut out players' riding images and recognize the position of the players.Automatic creation of highlight images of tournaments and efficiency of tournament management can be realized.
Another usage is that if you shoot a soccer game in the near future with one 8K camera, and if the viewer specifies "I want to see this player", it may be possible to follow the player.。
At present, only one person can be cut out, but it may be possible to cut out two people at the same time and cut out at the same time.
Combine 4K and 4K images, cut out 8K beautiful images, and distribute them to smartphones.I waved my hand, but there is no delay at all
Local MEC is a concept/research stage that realizes ultra -low -delay services for non -specific areas in sports competitions and artists' concerts at stadiums.In the video distribution so far, if you distribute the way you waved your hand, there will be some delays in hand movements, but the technology called local MEC will demonstrate a service that does not delay the movement of the hand and the actual video that is actually visible.I was.
For example, even if you are sitting in a bad seat that you can't see at the stadium, a camera video with a good -looking seat will be distributed to your smartphone.If it is a local MEC, there is no delay in the play and distribution video of the stadium, and even if you enjoy playing and video at the same time, you can experience it without any discomfort.
OMRON exhibits the demonstration experiment/POC stage table tennis robot "Forpheus".The fifth generation table tennis robot was on display.The other day, CES in the United States exhibited a 6th generation table tennis robot, but it is a different version.
If you actually look at the robot play, it's pretty good.According to the staff, it is quite strong in the hot spring table tennis world.It is said that if you play with a professional player, you will not be able to win, but it will be able to have a good rally to the general public.
Surprisingly, the cameras, robots, and PLCs used in this robot are all operating in industrial factories, and there is nothing specially customized for table tennis robots.Everything is realized by combining the products listed in the Omron catalog.
For example, the robot part is a robot called a parallel link mechanism, which uses a device that grabs things in a factory called pick -and -place and place them elsewhere.Regarding the camera, Omron has a lot of cameras to see things, and one of them is used.
For sensing, use five cameras, detect the position of the ball with two cameras, detect the position and posture of the player with one camera, and move the player with two cameras.It is said that it is sensing.
Omron has no plans to sell table tennis robots, and we are not considering the development to strengthen robots to invincible levels.OMRON is aiming for the reconciliation of people and machines, and is thinking about developing robots to see more players.In the future, he is focusing on the development of robots that will entertain players and grow more and more players.
The next -generation security robot that has already begun to be practical is exhibited.You can perform a patrol inspection, check the door, and check the lights of electricity.It is equipped with six cameras, and it is equipped with a function to send data to perform face authentication, measure infrared cameras and temperature to perform various checks.Also, like the Vacuum cleaner Rumba, automatically charging the charging stand is automatically charged.Continuous driving is available for 8 hours.
The opening and closing of the key compares the normal image and the image of the development and reports, "If there is a difference, the key is open."The lighting check of the electricity is also checked by the difference between the glowing state and the disappearing state.If there is an abnormal place, it is said that the guard is used in the form of a guard to go to the report.
As you approach the virtual security system in the center of the photo, the perspective of a life -sized security guard turns here.It is also a feature that you can feel the same gaze like a guard as a human.
The Virtual Security System is a virtual character that plays a role in some of the resident guards at the entrance of office buildings and factories.
It is said that the purpose of a person who actually stands and guards is meaningful to think about it when a good person is approaching.Therefore, the virtual security system, a life -sized character, is equipped with a function to chase people from the perspective.People approaching feel the impression of the actual people.It can be psychologically as effective as human security.
In addition, regarding the standard questions that are frequently asked in places where security guards such as "Where is the toilet?" Or "Where is the nearby convenience store?" Possible.
If you are at the entrance of the building, it will be a special response to the officials of the employees by registering the VIPs and frequently entering and exiting faces, opening the door, unlocking the key, directly informing employees involved.
If there are people who are not able to cope with virtual security, or if some people are making noise, it will be a method such as a real resident guards can respond to the microphone remotely or directly respond.
In the near future, if three people need to guard at the entrance of the building, three virtual security will be placed and followed by a single operation table.It will be possible to need three human security guards alone, making it easier to respond to the era of labor shortage.
Demonstration of remote assembly work that grabs and stacks things
There were many demonstrations related to remote control.A demonstration of a remote control robot in the concept/research stage, which combines power touch technology and remote control robots to perform remotely control robots.Power touch is a soft and hard feeling in human sense.By using power touch transmission technology, this operator in a remote area gives a sense of being in the spot, as hard, soft.In other words, by using a transmission technology, it is possible for the robot to hold the hand and convey softness and hardness to the grip.
By transmitting a sensation, it is possible to hold a soft thing like a paper cup, but not to crush it through the hand while watching the video distributed in real time.If you don't have a strong touch, you'll have no sense of crushing.This makes it possible to grasp soft foods through robot hands.
