I recently bought a ZED XOne S Camera without Lens and a ZED XOne GS Camera without Lens. I first mounted on a lens on the camera. Then, I wanted to preview it on ZED Studio but it wouldn’t work because of invalid calibration file. Then I tried to use your ZED OpenCV Calibration tool but then the GUI wouldn’t pop up. I have attached the things I was seeing, but overall I was hoping to get help regarding how to see a preview of my camera view. Thanks!
Terminal Output after trying to run OpenCV Calibration:
./zed_mono_calibration
*** Monocular Camera Calibration Tool (ZED X One) ***
The calibration process requires a checkerboard of known characteristics.
-
Expected checkerboard features:
- Inner horizontal edges: 9
- Inner vertical edges: 6
- Square size: 25.4 mm
Change these parameters using the command line options if needed. Use the ‘-h’ option for help.
-
Lens distortion model: Radial-Tangential
-
Camera Model: Unknown
-
Camera Serial Number: 0
-
Camera Resolution: 0 x 0
-
Using prior calibration: No

When testing a custom kernel, it is recommended that you create a backup of
the original kernel and add a new entry to this file so that the device can
fallback to the original kernel. To do this:
1, Make a backup of the original kernel
sudo cp /boot/Image /boot/Image.backup
2, Copy your custom kernel into /boot/Image
3, Uncomment below menu setting lines for the original kernel
4, Reboot
