The OpenBiomechanics Project (OBP) is an initiative committed to providing free, high fidelity, elite-level athletic motion capture data to the scientific community. Our aim is to first advance research in the sport biomechanics and high-performance domains followed by expansion to the broader movement health space.
OBP provides C3D files as well as processed biomechanics data (time-series and point of interest metrics) to accommodate those interested in endpoint or starting point data. Documentation detailing metric definitions, variable and file naming conventions, and processing steps is also provided.
It also includes synchronized genlock video samples of human movement along with tutorial Python scripts – the OBP Computer Vision Project.
Currently, the OBP data repository contains data from 100 pitchers and 98 hitters from the Driveline Baseball database.
OBP is the largest high-fidelity, open source set of raw and processed motion capture files on elite baseball players in the world.

About Us
The OpenBiomechanics Project was founded by Driveline Baseball Research and Development, the world’s leader in data-driven baseball player development.
We aim to democratize access to elite-level motion capture data, accelerate progress in the sports biomechanics field, and increase collaboration between researchers in academic and industry settings.
