A full bar in the quality column is the best ranking.
A relatively high Error for a BTSensor indicates that the given BTSensor received poor
samples during calibration. Restart the wand calibration process. At least two
BTSensors must have vision of the calibration wand for data to be captured for
calibration. There is a progress bar in the Results column to highlight the quality of
each BTSensor.
While calibrating, BTSensors initially attempt to calibrate for the lowest level of quality.
Once BTSensors have met the criteria of that quality level, the system will advance to
the next level quality and attempt to calibrate. This process repeats until the highest
quality calibration based off the data has been achieved. Once exceptional quality had
been achieved, the system will apply the calibration automatically.
In the Perspective View window you can see a visualization of the wand sample
collected for calibration. The position of BTSensors will move to match their position in
the physical Space as the system determines their location.
Once the rating for each BTSensor reaches “Excellent” or greater, and the Overall Results quality5.
rating reaches “Excellent” or greater, the calibration results will automatically be applied to the
system.
To apply the calibration manually
In the Calibration Engine section click Apply Results.1.
Result: The Calibration Results Reports window will open. Calibration results are
available
In the Calibration Results Reports window click Apply.2.
Result: The calibration data will be applied to the BTSensors and they will know their
position in the Space in relation to each other. BTSensors positions can be viewed in
the Perspective View window in Motive. Ground plane calibration is required next to
determine the BTSensor’s position relative to the origin (if using a Refine calibration,
you may skip ground plane calibration).
In Motive 2, click the File menu and select Save Current Take or click File menu and select Save6.
Profile. In Motive 1.10 or lower , to save the changes to the project file, click the File menu and
select Save Project.
Partial BTSensor Calibrations
As mentioned above, it is possible for the user to calibrate sections of their BTSensor setup after the
initial calibration, as opposed to having to recalibrate the entire BTSensor setup (as of Motive 1.10).
The partial BTSensor calibrations are based off either a Full or Refine calibration as you would do above.
To be able to complete a partial calibration, Motive needs the calibrated BTSensors as reference. These
are known as Anchor Cameras. You need at least 2 of these anchor BTSensors, in addition to the
BTSensors you wish to calibrate in order to complete the calibration successfully.
To complete a partial BTSensor calibration
In Motive, change the layout to Calibration preset. From the Layout menu, choose Calibration.1.
Go to the Camera Calibration pane.1.
Choose either a Full or Refine calibration based on the guidelines above.2.
In the Calibration tab, under the Wand Option heading, set the OptiWand sub-heading3.
