Method 1 – Importing a Calibration File With a Connected System
Step 1 – Open ZEISS Correlate
Launch ZEISS Correlate on the computer connected to your ARAMIS system.
Step 2 – Access the Setup Workflow
There are multiple ways to add a calibration file depending on your setup. When connected to an ARAMIS system, the recommended approach is to follow the standard workflow sequence displayed from top to bottom and left to right within the software.
Begin by clicking the Setup button.
Step 3 – Prepare the Sensor and Camera Settings
Within the setup workflow, proceed from left to right to configure the system:
- Set up the sensor
- Adjust camera focus
- Set the appropriate aperture
These steps must be completed before performing the calibration.
Step 4 – Open the Calibration Panel Tool
As the final step in the setup workflow, click on the Calibration Panel icon. This opens the calibration interface and prepares the system to capture images using a calibration object.
Step 5 – Review the Currently Loaded Calibration Panel
At the top of the calibration panel interface, verify whether a calibration panel is already selected. Else a new can always be added.
If a calibration panel is loaded:
- Confirm that all information is correct, including
- Ambient temperature
- Calibration object details
- If everything is correct, continue with the calibration process.
Step 6 – Import a Calibration File
If a different calibration object is required, click the folder icon to import a calibration file from a local directory or USB thumb drive. It should be a .calobj extension.
In this example, a CPA10 calibration object is imported.
After selecting the file, some values in the menu may update automatically.
Step 7 – Verify Calibration Object Parameters
After importing the calibration file, it is critical to verify that the distance values and parameters match the information printed on the tag attached to the physical calibration panel or cross.
Click the Edit icon to review these values.
Distance Definition for Calibration Objects (Only works for CP20 and CC20)
If needed, two distances can be defined as following:
- Distance 1: From the top‑left coded marker to the bottom‑right coded marker
- Distance 2: From the top‑right coded marker to the bottom‑left coded marker
Example with CP20 (Calibration Panel):
Example with CC20 (Calibration Cross):
Ensure these values exactly match the dimensions specified on the calibration object tag.
Step 8 – Confirm and Continue Calibration
Once all parameters have been verified:
- Click OK to confirm the calibration object settings
- Continue with the calibration process by capturing images according to the on‑screen instructions
Method 2 – Importing a Calibration File Without a Connected System
This method is used when no ARAMIS system is currently connected, but you still want to import and prepare a calibration file for later use.
Step 1 – Open ZEISS Correlate
Launch ZEISS Correlate on your workstation. No system connection is required for this workflow.
Step 2 – Navigate to the Calibration Menu
From the top menu bar, follow this path:
Acquisition → Sensor → Calibration → 2D or 3D Calibration from Image Series
Step 3 – Access the Calibration Interface
Selecting one of the calibration options opens a calibration interface that is similar to the one used when a system is connected, as described in Method 1.
From this point onward, the workflow is largely identical.
Step 4 – Import the Calibration File
Within the calibration interface:
- Click the folder icon to import a calibration file from a local directory or USB thumb drive
- Select the appropriate calibration file (for example, a CPA10 panel with the .calobj extension)
For any CC40 or CPA panels, you can only import the .calobj file. This file is included on the dongle. You can usually find it in the manual or inside the drawer if you have a full station.
Step 5 – Verify Calibration Object Parameters
After importing the file:
- Review all calibration object parameters
- Confirm that the distance values and dimensions match the information printed on the calibration object tag
- Use the Edit icon to inspect or modify the distance definitions if needed
Distance Definition for Calibration Objects
If needed, two distances can be defined as following:
- Distance 1 is defined from the top‑left coded marker to the bottom‑right coded marker
- Distance 2 is defined from the top‑right coded marker to the bottom‑left coded marker
Example with CP20 (Calibration Panel):
Example with CC20 (Calibration Cross):
Step 6 – Save and Continue
Once all parameters are verified:
- Click OK to confirm the calibration object
- The calibration file is now available for use when performing calibration with an ARAMIS system
Summary – Choosing the Right Method
- Method 1: Use when an ARAMIS system is connected and ready
- Method 2: Use when no system is connected but calibration files need to be imported or prepared in advance
Both methods ultimately use the same calibration interface, and once the calibration menu is open, the remaining steps are the same.
✅ Notes & Best Practices (Optional Section)
- Always verify calibration object values after importing a file
- Ensure ambient temperature is accurate before proceeding
- Re‑calibrate if the setup or environment has changed
