[mitk-users] IGT Navigation Tool Calibration

[LOPEZ VELAZCO, ROCIO]

Hello,

I am new in Navigation with the MITK software and I would be very grateful
if you could help me with some questions.

I am using a Vicra Polaris tracker and I am trying to perform the
registration using the Polaris pointer so that navigate a physical model.

My main question is how to perform the calibration of the tool so that
knowing the exact position of the tip of the pointer. I have been watching
the IGT Navigation Tool Calibration view and you offer possibilities such
as manual, single reference tool, multiple tools reference and pivoting
methodologies. I am familiarized with the pivot calibration (performed
with other software) but I have seen that it is not fully implemented yet
<http://docs.mitk.org/nightly/org_mitk_views_calibrationtoolmanager.html>
in MITK. If I calibrate the Pointer with the NDI ToolBox I obtain the
offset of the tip, however I tried to copy this offset in the translation
section of "manual calibration" of MITK and I found that I can't annotate
decimals, and even if I round numbers it isn't close to be OK, so I guess I
am doing something wrong. Could you give me any tip to perform the
calibration of the Pointer? (I do not have any other reference tool).

I wonder as well if it is normal that the Workbench gets too slow when I
connect the tracker? Just to understand if something might be affecting the
navigation?

My last question is about transformations, is there any plugin or GUI
function that manages transformations? For example, if I want to apply a
transformation to a concrete object?

Thank you very much in advance.

Best Regards,

Rocío López
