Probe Calibration


This guide outlines the calibration process for the CeConstructor probe, ensuring accurate surface point capture.

Step 1: Understanding the Probes The CeConstructor uses probes of varying sizes tailored for specific surface point capture tasks.

Step 2: Components of a Probe Each probe is made up of a detection pattern and a tip. Calibration determines their alignment.

Step 3: When to Calibrate? Calibrate during:

  • First Initial system start-up.
  • Mechanical disturbances.
  • Temperature changes above three degrees Celsius.

Step 4: Selecting a Probe Multiple probes can be stored in the system. Switch between them under “Settings.”

Step 5: Preparing for Calibration For best results, mount the cameras on the calibration tripod at the smallest base distance.

Step 6: Starting Calibration Position the probe’s tip in a recess or on a rough, non-yielding surface. Ensure it remains stationary.

Step 7: Using the Digital Template After the first capture, a digital template appears. Fill the remaining circles with additional captures.

Step 8: Quality Assessment Post-capture, a quality error value in mm is displayed. If too high, repeat the calibration. Save successful calibrations with “Overwrite.”

Step 9: Understanding the Error Value The error value indicates working accuracy. Adjust based on accuracy needs.


After calibration, the probe is ready for surface point capture.


  • The probe tip must not move during calibration.
  • The probe must be held still at the time of recording. Any movement will degrade the recording quality.
  • A calm and focused approach leads to success.
