Calibration Using Calibration Cross CC 30
Sensor Calibration
Please follow the instructions until the end of the calibration process.
In order to capture the entire measuring volume, you need to move
the sensor during calibration. For this, the following general rule ap-
plies: You should move the sensor by 1/3 of the measuring volume
height closer to the object and by 1/2 of the measuring volume height
further away – in each case starting from the center of the measuring
volume.
After you recorded the last calibration image, finish the calibration with
Compute.

10.4.5 Calibration Result

At the end of the calibration process, the calibration result and the
scale bar deviation are shown with icons. The green icon indicates
a good result. The red icon indicates an insufficient result.
In case of an insufficient result, repeat the calibration and check the
sensor settings (see 8.4), the correct lenses and ensure that the
lenses are mounted tight.
You reach the calibration results with Acquisition ► Sensor
►Calibration ► Show Calibration Information.
As of software version V7.5 and higher, the calibration is stored in
the ATOS COMPACT SCAN SENSOR.

10.4.6 Quick Calibration

If during a measurement it is indicated that the system might be
decalibrated (e.g. if you slightly knocked against the cameras), you
may perform a quick calibration.
You reach the software dialog with Digitize ► Sensor ►Calibration
► Quick Calibration.
During this process, the calibration object needs to be placed into
three positions - in the center of the measuring volume, further away
from the sensor and closer to the sensor. These three new images are
combined with the original calibration and thus a new calibration is
calculated for the following measurements.
This method is fast and can easily be used during recording a meas-
uring project.
However, the image characteristics of the cameras must not have
changed! If, for example, you inserted new lenses, you need to per-
form a complete new calibration!
The calibration cross must not have been taken apart during the last
calibration and the quick calibration!
