The Optitrak Motion tracking system consists of infrared-emitting and -sensing cameras positioned to triangulate and extract information about the location, movement, and orientation of rigid bodies.
Calibration
Tracking Tools software
If you are interested in using only a single tracker or a few trackables (rigid bodies with trackers configured at fixed positions), use the Tracking tools software for optitrak calibration.
In order to calibrate, you:
- Use the wand to register the area of interest
- Use the plane to set the ground plane
- If using trackables, create trackable objects
- Set the data to stream out (for reading into matlab)
ARENA software
-wizard -> calibration -sometimes says camera 0-x, ?? -make sure cameras 1-6 (or whatever's appropriate) -next, camera preview- remove any reflective surface you don't want the cameras to pick up -if you see any points you can't remove physically, block all visible points (but this a last resort solution) - -right click for option to change to grayscale to see what cameras are actually recording (useful if changing camera positions, i.e., not in established real room setup)
-next, start wanding- it's important when wanding that wand is visible to as many cameras at possible for most of the time -next -next, set ground plane -next, capture volume preview -next, save calibration results
-refer to the arena website for videos demonstrating how to position markers on black velcro suit - -record in t-stance until 34 markers registered at the same time (may have to dance around a bit)
Streaming Data to Matlab
- right side panel has stream tab -can choose unicast and ip address to stream to e.g., matlab on same computer or different computer
