Make sure the calibration correct or not

Hardware ZED2

Hello,

I am not sure about our Stereo Camera ZED 2i’s calibration correct or not.
Also, it shows for both left and right camera fx, fy, cx and cy values are the same. Even if I change the camera angle it always shows same angle.

Hi @MasudRanaMunna
Welcome to the Stereolabs community.

You have retrieved the RECTIFIED camera parameters, so what you observed is correct.
I recommend you read this support page to learn more about this topic:

@Myzhar Thank you for your prompts replay. How could I ensure the stereo depth information in physically. Like I get the depth of information of an object through Stereo camera, now how I get the physical dimension of the object?
Thank you.

Hi @MasudRanaMunna
I recommend you explore all the examples that we released on GitHub.
The ZED documentation is always a good resource.
