Braid is multi-camera acquisition and tracking software. It is useful for 3D tracking of animals, robots, or other moving objects. It operates with low latency and is suitable for closed-loop experimental systems such as virtual reality for freely moving animals.
Individual cameras are controlled with Strand Camera for low-latency 2D tracking without the use of markers and video recording to disk. Braid synchronizes multiple copies of Strand Camera and provides low-latency 3D tracking.
Braid is the successor of flydra, and is the result of a rewrite focused on performance, ease of use, and flexibility.
The documentation for Braid (and Strand Camera) is here.
Releases are provided via GitHub.
Ubuntu Linux (64 bit Intel/AMD) is supported. We test internally on macOS and Windows.
Braid is free and open source software.
