Calibration - Overview
I cannot cover two thirds of the measurement volume within the set time for the
room calibration. How do I extend the time for the calibration process?
Please open the dialogue
can extend the duration for the calibration process. Please refer to chapter 9.1 on page
100 for more information.
How shall I evaluate the room calibration results?
Please refer to chapter 9.1.4 on page 103 for a detailed explanation.
DTRACK3 reports the error message "no angle tool detected". What went
wrong?
First of all, please double-check if all markers are visible and that there are no disturbing
reflections. Sometimes, it might help to move the calibration angle a little bit.
Please always verify the settings for the room calibration before repeating:
wand length is printed on a label on the wand;
select the correct calibration set.
The progress bar of the room calibration stopped.
Please double-check in the

What is a "re-calibration" and when do I have to perform one?
DTRACK3 provides simplified room and body calibrations, called room and body re-
calibration. The main advantage of a re-calibration is that
and the orientation of your coordinate system as well as specific information (predefined
emission vectors, cylindrical marker).
You may perform a room re-calibration from time to time or if a camera moved slightly
(e.g. due to mechanical instabilities).Please refer to chapter 9.1.5 on page 104.
If your body fell down or if the structure is bent you should carry out a body re-calibration.
Please refer to chapter 9.5.7 on page 128 for more information.
