The Emergence and Application of 3D Athlete Tracking Technology

01、Introduction

The Olympic Games, this globally watched sports extravaganza, is not only a stage for athletes to showcase their strength and speed, but also a fashion show in the tech world.

Here, every referee's whistle might become a turning point in the competition, just like pressing the pause button in an intense and exciting game.

But as the pace of the competition quickens and the rules become more complex, traditional referees' naked eyes can no longer accurately judge the athletes' performance and fail to notice every detail, easily causing disputes between the audience and the athletes.

But don't worry! Our AI referee - 3D Athlete Tracking Technology (3DAT) has already debuted! Now, Document Jun will take you to understand what 3DAT is!

02、What is 3DAT Technology

3DAT technology is a kind of technology used in speed racing sports, which combines computer vision technology and AI deep learning algorithms. Through the configured high-speed cameras, it can generate the corresponding 3D layer without the need to use special sensors or devices.

This technology can capture and analyze the athletes' movement data in real time, providing a scientific basis for the athletes' training and competition. At the same time, it can also be replayed after the competition, and there is no need to worry about referee's misjudgment anymore!

03、How 3DAT Technology Works

So how does 3DTA technology work? Take the sprint event as an example, 3DAT technology defines multiple motion capture points on the athlete's whole body, and extracts key skeletal point information, key body postures, knee angular velocity and other data during the movement.

Using these data, 3DAT technology generates a parameter set of the athlete's biomechanical data. Through accurate posture analysis and data aggregation, it provides important basis for evaluating and guiding the athletes' competition. The whole process takes only a dozen minutes at the shortest, and the specific process is shown in the figure below.

04、Characteristics of 3DAT Technology

Real-time: 3DAT technology can provide video data analysis results within a dozen minutes, ensuring the timeliness of the data and supporting coaches to obtain data on the spot and make immediate adjustments.

High precision: Through key skeletal point information extraction and 3D reconstruction technology, 3DAT can accurately obtain the state of the athlete in terms of sprint speed, acceleration and biomechanics, with a measurement accuracy up to millimeter level.

Wide range: Based on the advanced AI analysis model, 3DAT technology only needs to deploy a small number of camera devices to cover a wide training field, simplifying t he process of system deployment and transfer.

No interference: Athletes do not need to wear sensors and other equipment that affect the sports effect. The system can directly extract data from the training video for analysis, achieving zero interference to normal training.

05、Applications of 3DAT

So is 3DAT technology only used in sports events? Of course not!

Formulating training plans: When training, using 3DAT technology to feedback sports data in real time can allow coaches to know the athlete's defects faster and make plan adjustments as early as possible.

Artistic effect: In the opening ceremony of the 2022 Winter Olympics, 3DAT technology had already appeared. In the opening ceremony site, only through 4 cameras, it covered the whole field and enabled the actors to interact in real time with the large screen laid on the site, successfully creating a beautiful artistic effect.

06、Future Outlook

With the development of technology, 3DAT technology may become an indispensable part of our daily life, and we can analyze our own movement data in real time and customize personal movement plans and strategies! It will no longer be an unreachable black technology, but a practical tool that everyone can access and utilize.

Let's wait and see how 3DAT technology will continue to write its new chapter in sports science and daily life and bring us a more healthy, active and technology-filled future!
