One System for Body, Bat, and Ball

Stop stitching together radar, sensors, and motion capture after every session. Theia3D gives you a single, synchronized dataset so you can spend less time processing data and more time coaching.

A Workflow Built for Coaching

Movement and ball data are often captured separately. Theia3D brings body, bat, and ball data together in one dataset so you can understand what’s truly driving performance.

One synchronized dataset

Every rep captures full-body kinematics, bat path, and ball trajectory together in a single synchronized dataset. No merging files or syncing data between systems after every session.

Seamless, markerless capture

No suits, sensors, or setup before each rep. Theia3D captures athletes in normal clothing, moving exactly the way they would in a game.

Works anywhere you coach

Many systems require a fixed install or dedicated lab space. Theia3D runs from standard video footage captured where athletes already train, including cages, the mound, and the field.

From Cameras to Clean Data in Minutes

Theia3D turns everyday training footage into clear, usable data with a fast, three-step, markerless workflow. No sensors, no lab setup, and no extra workload on staff. Just trustworthy data coaches can put to work right away.

Step 1 – Calibrate

Use a standard wand or your proprietary Theia3D calibration board (shipped at purchase) for flawless and fully automatic motion capture setup. This minimizes errors and optimizes data collection, ensuring top-tier accuracy.

Step 2 – Record

Capture multi-camera video in your environment with subjects wearing their everyday clothing. No preparation or spandex suits required. Allow natural movement in the environments that matter.

Step 3 – Analyze

Leverage Theia3D’s motion capture technology to track 124+ keypoints for precise 3D skeletal models. Load videos and calibration files into Theia3D to examine a single pitch or swing, or use Theia3D Batch to automatically analyze large datasets for efficient measurement reporting. Export data in multiple formats, including .c3d motion files, allowing seamless review and reporting of key metrics in customizable workflows.

Why Teams Trust Theia

Leading performance programs trust Theia3D to deliver accurate movement data from real training environments, helping coaches tailor training with confidence.

“Theia not only saves time, it gives us a clear link between the athlete’s movement and the resulting ball behavior, making it much easier to design individualized training based on the specific mechanical or physical factors actually driving performance.”

Frequently
Asked Questions

How is ball tracking captured without sensors?

Ball trajectory is reconstructed using synchronized video from multiple cameras.
The system uses computer vision models to track the ball in 3D space without requiring any sensors or radar systems.

Does ball tracking require bat tracking?

No. Ball tracking can be used independently or alongside bat tracking and biomechanics modules, depending on your workflow.

How accurate is the system?

Theia3D is supported by 50+ independent peer-reviewed validation studies in biomechanics. Ball tracking builds on the same multi-camera, synchronized capture approach, enabling consistent measurement across body, bat, and ball.

Can this be used outside of a lab or stadium?

Yes. The system is designed to work in real training environments, including cages, fields, and performance facilities, without requiring fixed infrastructure.

How is this different from radar or stadium tracking systems?

Radar and stadium systems primarily measure ball flight. Theia connects ball trajectory to biomechanics and bat movement in a single synchronized dataset, enabling cause-and-effect analysis.

What equipment do I need?

A high-speed video setup (300 fps or higher) with 6+ synchronized cameras, and Theia3D with the ball tracking add-on. No markers, sensors, or specialized installations are required.

What kind of users is this designed for?

Professional teams, collegiate programs, training facilities, and biomechanics labs looking to connect movement to performance outcomes.

Can this replace multiple systems?

In many workflows, yes. Theia3D consolidates biomechanics, bat tracking, and ball tracking into one system, reducing the need to align separate tools.
