Hi Julien,
We are having some problems with the calibration using the FOB tracker.
Patrick told me you implemented the FOB classes before the refactoring.
Where you able to run the pivot calibration with good repeatability?
Do you remember why you set the transformation in igstkFlockOfBirdsTracker
in this way?
typedef TransformType::VersorType RotationType;
RotationType rotation;
rotation.Set(quaternion[0],-quaternion[3],quaternion[2],quaternion[1]);
//<---- why minus and why that order?
Anything you can contribute would help us a lot
thank you,
sebastian
