scikit-surgerynditracker is a python interface for Northern Digital (NDI) trackers. It should work with Polaris Vicra, Spectra, and Vega optical trackers and Aurora electromagnetic trackers. Tracking data is output as NumPy arrays.

scikit-surgerynditracker is part of the SciKit-Surgery software project, developed at the Wellcome EPSRC Centre for Interventional and Surgical Sciences, part of University College London (UCL).
pip install scikit-surgerynditracker
Configuration is done using Python libraries at instantiation. Invalid configuration should raise exceptions. Tracking data is returned in a set of lists, containing the port handles, timestamps, framenumbers, the tracking data and a tracking quality metric. By default tracking data is returned as a 4x4 NumPy array, though can be returned as a quaternion by changing the configuration.
from sksurgerynditracker.nditracker import NDITracker
SETTINGS = {
"tracker type": "polaris",
"romfiles" : ["../data/8700339.rom"]
}
TRACKER = NDITracker(SETTINGS)
TRACKER.start_tracking()
port_handles, timestamps, framenumbers, tracking, quality = TRACKER.get_frame()
for t in tracking:
print (t)
TRACKER.stop_tracking()
TRACKER.close()
