Calibration Using Calibration Panel CP 40
Sensor Calibration
The CP40 calibration objects consist of black points on a white back-
ground. The larger points in the middle inform the ATOS software
about the calibration panel type, e.g. calibration object CP40 for mea-
suring volume MV320.
Each point was measured photogrammetrically in the factory. Not only
the black points are used for calibration but the white spaces as well
(calibration of individual cameras). Therefore, always ensure that the
calibration panel is clean (see section 9.3.1).
For each calibration panel there is a CD containing the calibration da-
ta (file extension .calobj) and the certificate.
A unique serial number provides for correct matching of calibration ob-
ject, certificate and calibration data.
Calibration CD with serial no. File name calibration data
Serial no. of calibration panel
Certificate with serial no.

Handling Instructions for Calibration Panel CP40
The surface of the calibration panel is very sensitive. Therefore, nev-
er touch the surface directly with your hands.
Calibration panels for measuring volumes with camera position 400
and 800 remain in the case during the calibration process. Only the
case cover is removed. Please remove the case cover carefully to
prevent any damage to the surface of the panel.
Clean the surface of the panel using the enclosed microfiber cloth
from the standard tool box. Wipe the surface gently only. Never exert
any pressure.
Damaged points will not be used for calibration. Dirty white areas will
be ignored during calibration and the process uses the clean neigh-
boring areas.
Soiling and damages in the area of the larger calibration points in the
middle may cause that the ATOS software does not identify the pan-
el!
If you use multiple ATOS Triple Scan sensors, please check that the
serial number of your calibration object matches the calibration data
in the software. The software only checks the correct type of the
panel but not the serial number.
It is mandatory that the serial number of the calibration object is iden-
tical to the serial number of the calibration object in the ATOS soft-
ware! Otherwise your measuring system may provide inaccurate
measuring data!
