Set the Center Distance (mm) field to 350.5.
Click Start Wanding.2.
Result: BTSensors record calibration wand data within the Space. The Calibration Engine
section records the samples of each BTSensor and the spread of the samples.
In the Physical Space, plug the power source into the calibration wand, and connect the1.
HPSU.
Result: The calibration wand’s LEDs should be visible in Motive as an infrared
source.
Wand the Physical Space by moving the powered calibration wand across the Space.2.
Move the wand up and down, back and forth, and rotate the head while you move, to
create different data points (think of a figure eight motion). Ensure the calibration wand
LEDs are not covered or being blocked from BTSensor view.
Tip:
When in use, the front facing LED on the Slim 13E BTSensor turns blue to
indicate that the wand is visible.
You must fill as much of a BTSensor's view with as much wanding data as
possible to improve calibration accuracy.
In Motive, look at the Camera Preview and Perspective View window. Perspective View shows all3.
BTSensors on the ground when they do the very first wanding. Examine each BTSensor’s recording
of the calibration wand. Wand samples are represented as colored lines. Each BTSensor is
represented by a unique color. Each BTSensor should have the same number of samples recorded.
Attention:
If a BTSensor will not record samples while wanding, consult the Camera Preview
window. See if other BTSensors are detecting the wand. If the wand does not appear on
any other BTSensors, the area will not calibrate due to lack of coverage. If the wand
shows up on at least two other BTSensors, continue wanding, but adjust the path and
angle of the wand to give the BTSensors different views. If a section of the intended
Space will not record samples after all of the steps above, cancel the calibration.
Reposition the BTSensors to obtain better overlapping field of views of the tracking
area.
If a BTSensor will not record samples while wanding, you may deselect the problem
BTSensor in the Camera window and recalibrate with the remaining BTSensors. The
area of the Space the problem BTSensor was covering may have less accurate tracking
or even no tracking available, but the rest of the Space should be accurate.
Note: The Calibration Engine section gives feedback about the BTSensor calibration,
including the number of times the calibration wand is viewed by each BTSensor. An estimate
on the quality of the calibration is displayed based on the number of samples which were
recorded. Calibration quality can be: Low, Medium, High, or Very High.
Click Calculate.4.
Result: Motive starts to calibrate BTSensors based on the collected data. The current state of
calibration is displayed at the top of the Calibration Engine followed by the calibration result
rating and the overall quality.
Note:
The calibration data captured in Perspective View is colored to indicate data accuracy.
Blue: Less than 6mm accurate in that area.
Red: Greater than 88mm accurate in that area.
The calibration engine displays a quality rating for all BTSensors as well as the global
average and the wand average based on the Desired Quality. The quality ratings are (in
order from worst to best): Poor < Fair < Good < Great < Excellent < Exceptional.
