ZED_Calibration Error 3 "Unable to open ZED camera" - X One GS works in ZED_Explorer

Hi,

I’m encountering a systematic error when attempting to start the calibration sequence with ZED_Calibration software:

[ZED Calibration] Unable to open ZED camera. Err : 3

Hardware: ZED X One GS

Observation: The ZED_Explorer software has no issues accessing the camera and successfully displays the video stream, which suggests the camera hardware and GMSL2 connection are functioning correctly.

I have the ZED_Diagnostic_Results.json file available if needed for troubleshooting.

Has anyone encountered this specific error with ZED_Calibration while other ZED software components work normally? What could prevent ZED_Calibration from detecting the camera when ZED_Explorer can access it without issues?

Thanks for your help.

Hi @cl_nx
Welcome to the Stereolabs community.

The current version of the ZED Calibration tool only supports the Stereo camera models.
We will upgrade it to support monocular cameras in future versions.

Why do you want to calibrate your monocular camera?
All the ZED X One GS with fixed optics are factory calibrated.

Hi Walter,

The camera we purchased has no optics.

In this case, you can use OpenCV for a standard intrinsic calibration.

Do you plan to use the camera in a dual virtual stereo setup?

Hi Walter,

No for the moment the ZED X One camera will only be used a simple stream capture.

I wanted to perform the camera calibration after having sealed the lens on it to be able to use Stereolabs software features of frames post-treatement that required cpmplete calibration parameters to be determined.
