• To point at calibration point number 1, press and hold the F3 “Laser”
key to start the laser. When the laser hits the stagemark, release the F3
key: this will turn off the laser, record the stagemark position and
advance to the next screen.
• Repeat the above procedure to point at calibration points 2, 3, 4 and C.
If you make a mistake you can always press the “cancel” button to go
back one screen and repeat the step.
• After recording the last calibration point a screen will tell you if the
calibration was successful and show the 3D coordinates and orienta-
tion of the TrackPod. Press OK.
• The system will ask you to point the laser at the downstage corners of
the stage. This is to match the virtual world with the real world in case
the stage marks are slightly offset from the stage centre or rotated. If
the laser cannot reach the downstage corners you may simply point it
more or less in the appropriate direction and later you can correct the
offset values in the stagemark inspector in the PC software.
• Press any key to go back to the start-up screen... you are done!
Tip: all TrackPods connected to a PC should be calibrated using the
same stagemarks. To facilitate this, you only need to enter the distances
between the stagemarks once and simply choose the “use existing”
option to recall them in subsequent calibrations.
Manual calibration
Manual calibration should be used only if for some reason automatic
calibration is not possible, for instance, if you can’t use the laser due to
stage obstructions. To use this method you must measure the exact
position in metres (or ft-inches) of each TrackPod relative to the origin.
