What is best way to calibrate the ZED X MINI camera and verify that calibrations are okay

Software

Hi, I would like to (re)calibrate my ZED X MINI. Poses using GEN_1 Ultra seem pretty bad and I can’t seem to explain why this is happening. One guess is that the calibration of the camera (intrinsics,IMU) maybe off. I would like to eliminate this as a reason as to why the poses are bad.

Ideally, If there’s a native tool by ZED for calibration, that would be ideal and I don’t have the tags etc for Kalibr calibration at the moment.

How can I calibrate the ZED X MINI (IMU,intrinsics)? How can I verify the current calibration of the ZED?

Thanks!

Hi,

A calibration tool is available in the ZED SDK folder, in tools/. You can use it to calibrate the intrinsic parameters of your camera.
For the IMU calibration, open a terminal and run "ZED Calibration.exe" --calib_imu

The camera must be completely static and placed on a flat surface. Even the slightest vibration can impact the final result.

I’ll give it a shot, thanks!

Hi Benjamin, thank you for your reply. I tried it with my zedx. However, the ZED_Calibration seems only work for ZED mini, while their output files are only 2k/FHD/HD. Could provide more guidance on how to calibrate the zedx camera?

Hi,

Can you share the calibration file generated by ZED Calibration please?
