Zed rotation calibration

Hardware ZED2
1

Hello Stereolabs!

I’m working on a custom gizmo to help me to calibrate my Zed2i, something pretty simple, like this, as I need to mount/unmount it a lot and I waste a lot of time doing it properly.

Using GetInternalIMUOrientation I can get X and Z values, but obviously Y is not measurable. As I test it against a flat wall, I was thinking of something like checking the distance diference between left and right cameras, but I don’t think that’s something I can do with this hardware.

Am I wrong? Do you have any other ideas about how I can achieve this?

Thanks a lot!

Hi @R2R0
you could consider using an ArUco tag:

Hey @Myzhar!

Thanks a lot for your answer.

I’ve never used ArUco, but I’ve been reading the documentation, and the example shown here https://www.stereolabs.com/docs/unity/using-opencv-with-unity

I guess the SDK has a way to detect the angle of the pattern, so I could be able to align my camera in this way, am I right?

It sounds like a good way to fix my issue, I’m now just wondering if there is a free way to get this? If not, yours sounds pretty solid, thanks a lot :slightly_smiling_face:
