Your Current Data Workflow is Slowing You Down

Disconnected systems create a slow, manual workflow that takes time away from coaching.

One synchronized dataset

Capture body, bat, and ball together in a single system, instead of stitching together radar, sensors, and motion capture manually.

Zero athlete prep time

Traditional systems slow sessions down with sensors and setup. Theia3D lets you collect more data without interrupting training.

No fixed installs required

Most systems rely on costly fixed installs or controlled setups. Theia3D lets you capture data from the cage to the mound to the field.

From Cameras to Clean Data — in Minutes, Not Hours

Theia3D turns everyday training footage into clear, usable swing 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.

Trusted by Coaches, Analysts, and Performance Teams

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

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.
