Stereo calibration for dual ZED X One cameras

[NivC]

Hi,

I’m working on stereo vision calibration using two ZED X One cameras mounted side-by-side to create a stereo pair compiling in C++ on ZED SDK V5.2.

I noticed that in the provided calibration example, the implementation is based on sl::camera.hpp and seems to assume a single camera instance. When I try to adapt the code to use CameraOne, I still end up with only one camera opening instead of two synchronized cameras (left and right).

My questions are:

1. Is there an official calibration example specifically designed for a dual ZED X One setup?

2. If not, what modifications are required in the provided calibration code to properly support two ZED X One cameras?

For example:

• Should I instantiate two separate CameraOne objects (one per camera)?

• How should the calibration parameters be handled and saved for both left and right cameras?

Any guidance or reference implementation would be greatly appreciated.

Yes, you can refer to this repository: GitHub - stereolabs/zed-opencv-calibration: Calibration tools to calibrate ZED cameras using OpenCV

You can find the full documentation here: Setting up the ZED X One Stereo - Stereolabs

@NivC

Should I instantiate two separate CameraOne objects (one per camera)?

No, this won’t provide Stereo capabilities.

@NivC

How should the calibration parameters be handled and saved for both left and right cameras?

Please refer to the documentation linked above.
