Research-grade markerless motion capture software that's completely free and open source.
Built for researchers, animators, athletes, and creators worldwide.
Position two or more standard webcams, GoPros, or smartphones around your space. Our universal design ensures high-quality results using everyday devices, requiring no expensive or specialized motion capture hardware.
Wave a printed ChArUco board within view of all cameras. This process automatically synchronizes the feeds and defines the 3D coordinate system required for accurate spatial reconstruction and tracking.
Perform your movements naturally while recording synchronized footage directly through the FreeMoCap interface, or simply record offline on your mobile devices to import the video files for later processing.
The local processing engine converts video into 3D data. Results are available in multiple formats, including CSV for analysis and FBX and .blend files for professional animation and research pipelines, along with many others.
The Free Motion Capture Project (FreeMoCap) aims to provide research-grade markerless motion capture software to everyone for free.
We're building a user-friendly framework that connects an array of `bleeding edge` open-source tools from the computer vision and machine learning communities to accurately record full-body 3D movement of humans, animals, robots, and other objects.
We want to make the newly emerging mind-boggling, future-shaping technologies that drive FreeMoCap's core functionality accessible to communities of people who stand to benefit from them.
We follow a "Universal Design" development philosophy, with the goal of creating a system that serves the needs of a professional research scientist while remaining intuitive to a 13-year-old with no technical training and no outside assistance.
A high-quality, minimal-cost motion capture system would be a transformative tool for a wide range of communities - including 3d animators, game designers, athletes, coaches, performers, scientists, engineers, clinicians, and doctors.
We hope to create a system that brings new technological capacity to these groups while also building bridges between them.
Everyone has a reason to record human movement.
We want to help them do it.
