If you use multiple ATOS Triple Scan sensors, please check that your
calibration object matches the calibration data you entered in the
software.
Make sure that the calibration cross does not touch the floor during
the calibration process as otherwise deformation effects may lead to
wrong results during the calibration.

Entering Calibration Data into ATOS
When using a measuring volume for the first time, you need calibrate
it and the corresponding calibration data need to be entered into the
ATOS software. If you purchased the measuring volume together with
the complete ATOS system, the calibration data is already entered.
Select workspace
Set Up
►
Calibrate Sensor
.
►
Click with the right mouse button (RMB) into the dialog and choose
Add Cross (coded) ...
.
Enter all required parameters of the calibration object into the software
dialog.
Please make sure that all calibration data are entered correctly into
the ATOS software!
Otherwise your measuring system may prob-
ably provide inaccurate measuring data!
9.4.3
Preparing the Calibration Process
When you want to calibrate a measuring volume, the sensor is already
set up (see section 7) and the ATOS software knows which measuring
volume and which camera position you want to use. Based on this in-
formation, the software determines the required focal lengths of the
lenses.
Open the calibration dialog in workspace

Maybe you are asked whether the settings are to be reset to the rec-
ommended calibration settings. This always happens when the cali-
bration object has never been used before or it was used in connec-
tion with a different measuring volume. Confirm the request with
Yes
.
In the following windows, enter the current measurement temperature
and accept the adjusted camera focal lengths.
Place the calibration object at the measuring distance in front of the
sensor using a stand (option). As the laser pointers are already ad-
justed to this distance (see section 7.4.2), you only need to move the
stand until the two laser points become one.
