illustrating the scanning angle does not have to match up with the blue line--it only needs to be
parallel to it as long as the scanner is still scanning the reference plate. A white arrow may appear to
tell you the direction that you need to rotate the handset to be perpendicular and parallel to the
reference plate. When the position of the handset is correct, the red
4
on the right side of the screen
will turn green and quickly count down to 0. If the handset remains in the correct position during the
countdown, then a green circle with a check mark will appear at the first compensation position, and
the second position will appear.
16. Repeat the step above for all compensation positions.
As soon as all positions have a green check mark the calibration of the device is checked, and, if
necessary, adjusted. After that, on-site compensation is finished.
Compensation Data and Report
The compensation data can be found on the Mobile PC under:
C:\ProgramData\FARO\Freestyle\cameras\
Compensation Report
The compensation report is saved as a PDF file. You can find it in your scan project folder, in a subfolder
called
compensationReports
. The Compensation report states whether the on-site compensation was
successful, and it shows some important data including the information below which may be necessary
for verification of accuracy.
Figure 10-5 Control markers on the reference plate
Target value of control marker distance
: This is the factory measurement of the distance between the
two control markers on the reference plate. The measurement is made photogrammetrically, and is
accurate to +/- 0.02 mm.
Measured control marker distance
: This is the distance that the sensor measured between the two
control markers immediately after the compensation process.
Distance deviation to target value
: This is the variation between the
Target value of control marker
distance
and the
Measured control marker distance
.
Cleaning Instructions for Lens Protection
The Freestyle 2 lenses are covered with protective glass that should be cleaned if it becomes dirty.
