TUNING
Unlike calibration (which is necessary step), tuning is optional and adjusts PPT's
tracking algorithms to the specific needs of your application.
Tuning is very important but it is quick to perform. Do it whenever your
requirements change, even if that means you tune once an hour.
For instance, if you plan to use PPT in a confined region and only with slow moving
objects (e.g., a person's head), then the process of tuning will let PPT optimize it's
internal parameters for that portion of your workspace and for objects moving at
that speed. Alternatively, if you plan to use every bit of trackable workspace at high
speeds (e.g., a dancer's body), the process of tuning will let PPT optimize accordingly
for this scenario.
Tuning your PPT system:
Before beginning, ensure that your PPT cameras are all properly configured and you
have a recent, good quality calibration . If not, then perform those steps first.
1. Turn off all of the PPT markers.
2. Ensure that no false lights can be seen in each camera. Check each camera
image in the Cameras panel and ensure that no lights detected (indicated by
yellow cross-hairs).
3. Turn on 1 LED marker.
4. Click on the Tune button and start sampling.
5. Move the marker around as if you were using it in your application. Make sure
that you cover the entire space the marker will move during your application
