Calibration
The Stagetracker II™ system must be calibrated for accurate tracking. The Calibration procedure is carried out
in three easy steps with the Stage Markers used in chapter 0 above
, and a charged Stagetracker II™ Tag. The
procedure is as follows:
1.
Find a charged Stagetracker II™ Tag and identify it by the
last
four digits in the MAC address found on the opposite side of
the TTA logo (see Figure 10). Press the Tag field and choose
the Stagetracker II™ Tag to be used for Calibration. Enable the
Calibration process by ticking the Enable checkbox.
Enable Large indicators to enlarge the quality indicators for each
Stagetracker II™ RadioEye during the Calibration procedure for
easier determination of quality from a distance.
2.
Place the Stagetracker II™ Tag on Stage Marker ID #1 with the
TTA logo facing upwards. Rotate the Stage
tracker II™ Tag until
the quality indicator for one (or multiple) of the Stagetracker
II™ RadioEyes
turns solid green. Move away from the
Stagetracker II™ Tag to avoid interference and press the
Collect button for the
Stagetracker II™ RadioEyes
which
indicators are green for Stage Marker ID #1. Repeat the
procedure for all
Stagetracker II™ RadioEyes and
Stage Marker IDs. The button will say Recollect if
there is data collected earlier.
3.
With all Stage Markers collected, press Calibrate for the first Staget
racker II™ RadioEye. A pop
-up
window displays the calculated calibration vectors, with the precision of each collection of data from
step 2, and an RMS error value for all data collected for the given Stagetracker Ii™ RadioEye.
An RMS error value of less than 0.20m is acceptable, less than
0.10m is great, and less than 0.05 is exceptional.
4.
Press OK to use the calculated Calibration and apply it to the
Stagetracker II™ system. If the RMS error value is not satisfactory,
the User can choose to press Cancel and Recollect data using Step
2. It is possible that the Calibration procedure results in several
mathematical solutions. Therefor it is good practice to evaluate
different combinations of the collected data by disabling and
enabling the Use checkboxes.
The Stagetracker II™ system is now calibrated and ready for use. See chapter
10 for setup of the individual
output modules.
Figure 18 The indicators for RadioEye SL
and Center are green and can be
collected. RadioEye SR should be
collected alone after rotating the
