<div class="gmail_quote"><div>Hi Julien,<br><br>We are having some problems with the calibration using the FOB tracker.<br><br>Patrick told me you implemented the FOB classes before the refactoring. Where you able to run the pivot calibration with good repeatability?<br>
<br>Do you remember why you set the transformation in igstkFlockOfBirdsTracker in this way?<br><br>typedef TransformType::VersorType RotationType;<br>RotationType rotation;<br>rotation.Set(quaternion[0],-quaternion[3],quaternion[2],quaternion[1]); //<---- why minus and why that order?<br>
<br>Anything you can contribute would help us a lot<br><br>thank you,<br>sebastian<br><br><br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

I asked Ziv to run his old code on Polaris to test the reproducibility. He said it was working before the refactoring, we might have broken something in the calibration class during the refactoring.<br>
<br>
That way, we can pin down the root of the problem. If the Polaris calibration works fine, then we know for sure, there is a problem with the FOB code.<br>
<br>
We also need integrate the MicronTracker code into the calibration example. When you are working with the CalibrationExample, could you try to make it work with multiple trackers? You can probably reuse some code from NeedleBiopsy.<br>
