9.8 Calibration

 

What does ’

scaling factor

’ mean?

Performing a room calibration results in a certain scaling error. This might be a problem
when applications do have very high accuracy requirements (e.g. when performing mea-
surements with the Measurement Tool ).
The scaling error can be determined, for instance, by measuring points on a defined
scale (e.g. tape measure). The determined scaling error can thus be adjusted with the

DTrack2

’

scaling factor

’ (refer to chapter B.1.1.1 on page 250).

Please contact

ART

if you require further information.

 

I cannot calibrate my target.

•

Please check if the markers of the target are seen by the cameras in good quality
(i.e. at least yellow) - a slight change of the target position might help. If necessary
increase the flash intensities of the cameras. Therefore, go to

Settings

→

Cameras

.

•

Make sure that when starting the body calibration every marker of the target is visible
to the cameras.

•

A body calibration can be carried out only if a valid room calibration has been carried
out before. Check in the

Event Display

if there is a warning saying ’no valid room

calibration’, additionally the button

Calibrate

is greyed out and cannot be clicked.

In that case, please carry out a new room calibration.

•

Please make sure using the

Monitor 2DOF

display that no marker is overlapped

(i.e. merged) by another one. If necessary rearrange the target and restart the body
calibration.

•

Try to carry out the body calibration with a moving target. Therefore, shift the starting
position of the target for calibration (often a shift of 10 or 20cm is enough to enable
calibration again).

•

Make sure that no other markers or targets are inside the tracking volume other than
the one you want to calibrate.

•

Please carry out a new room calibration.

 

I’d like to save all my body files for backup reasons but I receive less files than

configured bodies.

DTrack2

only creates body files for calibrated bodies. For example: if you configured 15

targets for tracking but only 4 of them are calibrated, you will only receive 4 calibration
files.
