3-marker Calibration Wands
3-marker calibration wands are used to calibrate the MX cameras. You
can create wands of different lengths with Vicon retroreflective
markers of different sizes.
The same handle section must be used for both the 240 mm (item 1
in Figure 12-1 on page 12-2) and 390 mm Wand Spacer Bars (item
5 in Figure 12-1). This handle section can be lengthened using the
Handle Extension (item 4 in Figure 12-1).
The 390 mm Wand Spacer Bar (item 5 in Figure 12-1) can be
extended to 780 mm for large volume calibration. To do this, remove
the marker (item 6 in Figure 12-1), attach the Wand Spacer Bar
Extension (item 7 in Figure 12-1), and then replace the marker at the
end of the extension.
10 Vicon CD “CRO Cal Files” Contains the
Ergocal.cro
Calibration Reference Object
file, which defines the
dimensions of the supplied
calibration objects, for use with
Workstation software on the
host PC. This file is installed with
the Workstation 5.x application
software. Keep this CD as a
backup in case the file gets
damaged or deleted and needs
to be recovered.
11 Calibration Marker Pack Contains 9.5 mm, 14 mm, and
25 mm marker sets to be
attached to the ergo calibration
frame (8).
