Calibration
41
In a more complicated calibration, you might have a physical workspace where not
all cameras can see the calibration rig simultaneously (e.g., the room is L-shaped).
In this case, you use the calibration wizard to successively capture views of the
calibration rig until all cameras have seen it. Your PPT will then automatically chain
all these independent calibrations together and form a single reference frame,
setting its origin and orientation at the first location of the calibration rig.
CALIBRATING
NOTE for PPT-X users :
Before running the calibration wizard, you need to be absolutely certain that your
cameras are connected in the correct order. To verify this, wave your hand or a
marker in front of each camera and double-check that each camera's physically
labeled number matches it's number in the PPT software interface. A mismatch
cannot be detected by the software and calibration will be possible but the calibration
quality will be significantly deteriorated. PPT-E and PPT-H systems automatically
identify themselves and ensure correct connections.
Standard calibration
In this method, all cameras are calibrated simultaneously.
1. Before continuing, ensure that you have configured your PPT cameras to
optimal sensitivity and thresholds, and that your workspace lighting is ready
for data collection (e.g., outside windows blocked, warm lights off).
2. Turn off all of your PPT markers.
