1.4 Calibration
By calibrating the scanner, the internal camera parameters are calculated. It is recommended to calibrate the scanner
each time it is moved or at least each month. If the scanner is placed on a stable table and kept at a constant
temperature, the calibration intervals can be increased. A calibration is always required when a scanner is first
unpacked.
An indication of a poorly calibrated scanner is a scanned model with a rough surface. When this happens, check if it is a
recurrent problem, as it might be attributed to the object not properly placed on the fixture. If the problem persists,
please contact your 3Shape support. No other maintenance besides calibration is required for the scanner.
Caution!
Beware that the scanner is a precision mechanical device sensitive to temperature and power
variations as well as vibrations.
The calibration is performed using the “dot plate” calibration object and the “square calibration object” supplied with
your scanner (see images below). The procedure is simple and nearly completely automatic:
1.
Make sure that there are no other running programs
2.
Click on the
ScanServer
icon in the system tray, and the ScanServer window will pop-up. Press the
Calibrate
scanner
button on the ScanServer window in the lower right part of the screen.
3.
A new window opens. Follow the detailed instructions in this window, which will guide you through the full
calibration process.
