Have a close interview with the second bullet of BOOST CREATIVITY SESSION!
Samsung's project "BOOST CREATIVITY SESSION" is a collaboration between the creator and SSD produced by Samsung. Through the introduction of Samsung's SSD in the production site, we can maximize the possibility of the creator and support the idea of creativity.
Last time, we interviewed the collaborative project "FUTURE STAGE" of VR artist Sekiguchi Aimi and exhaust rock band NEE (Nepal), which was implemented as his first play.
The theme of the second bullet is "FUTURE SPORTS". The event will feature Japanese national team Raimi Takai, who also participated in the Tokyo Olympic Games, using motion capture technology VTuber to transform his amazing physical fitness. How can the movements of Tujing players, who are both athletes and active entertainers in TikTok and other places, create new movements in sports? In addition, the existence of SSD in the scene of motion capture production is discussed through the interview.
For all creators, it is an indispensable existence of PC. The first play is made in VR space on the stage, while real-time monitoring the band's performance while shooting the form, so the large capacity of VR space readout and smooth ranging is the focus.
Connect the external SSD "Samsung T7Touch (supporting USB3.2 Gen2)" to the original PC for the creators made by the gallery, and record the actions while backing up.
This project will take Raimi Takei as the action actor, while capturing the different movements of ordinary people, at the same time quickly save its data in the PC backup. It can be said that the performance of SSD is more clearly related to productivity than last time.
The "mark" on the suit has become a reflective material that strongly reflects light.
For hand joints, etc., use small markers
It can be said that "motion capture" is also beginning to be recognized among ordinary consumers, on the other hand, except for some people who are interested in activities, it is an area where there are few opportunities to participate in the work. First of all, can you tell me the basics?
From the left, Takashi Suzuki, a technical support engineer in the fragrance motion capture division of Co., Ltd., a senior technical support engineer, and Shimada Yamada, director of the fourth production studio.
The common ways of "tail guard" are roughly divided into two categories, which are divided into "optical type" and "inertia type". Optics records the movement of the body, as the name implies. Attach small marks made of sparkling materials used in reflective materials such as sneakers to the body and use the camera to capture the reflected light.
Inertia is a way to obtain action from its data by installing sensors that can measure acceleration, angular velocity and geomagnetism on the body. The advantage of accuracy is that the optical formula has its own points, the optical formula needs a certain degree of breadth, and when the mark enters the dead angle of the camera, it is difficult to obtain the correct position. Inertia can be included even in narrow places, but it is easily affected by the magnetic field, so the data in places where the magnetic field is unstable is very likely to become unstable. "
The OptiTrack motion capture made by NaturalPoint Company is set on the pole with the camera "PrimeX" to record the action.
Accurately determine the location of the mark by shooting from high position and low position
-- this time it is included in optical style.
"Wei Wei" optical style. Combined with NaturalPoint's OptiTrack motion capture camera "PrimeX" and a camera called "Prime Color" used to record reference images. "
What is a reference image?
Data can be obtained only by cameras used for tail capture, but Prime Color can be combined with Prime Color to accurately synchronize live motion in frames and record it in high-resolution color images. Keep the reference video so that you can reference it later when you need to adjust or want to see the actual motion.
When the mark enters the dead corner of the camera, it is usually necessary to speculate and supplement the position, but through the shooting reference, you can refer to a more accurate location in the video. "
Camera "Prime Color" used to record reference images
It can not only determine the location of the mark more accurately, but also play the role of insurance when something happens. Where do you start when you have a chance to see the scene of motion capture on TV and YouTube?
Yamada, known as the T pose, has the basic posture of making a character. First of all, it is necessary to adjust the posture of the sensors installed on the characters and actors, adjust the angle of hands and feet, and so on. "
The basic pose, originally known as the "T pose", matches the position of the mark with the coordinates of the character.
-- so it is. Let's set the initial value or something like that.
Yamada: "however, depending on the character, the head is very big and part of the body protrudes, so when holding the head, the hand will be stuffed into the head on the CG."
At a time like this, do you want to make adjustments in the later processing?
Yamada: "Yes. Putting your hands in your head takes it for granted, and it's a job that needs to be done almost every time. "
