I m trying to do stereo matching but it doesnt work well until now. So i m trying to improve the procedure and when i launch calibration, i remarked origin of the landmark could change from a picture to an other... It could impact the quality of the procedure?

You have an example below : image description

The landmark in real world is represented in white with the 3 lines. Thanks for help ;)

In my opinion, you have to use a non symmetric chessboard pattern like in this tutorial. Otherwise, it seems that you have an ambiguity about the chessboard frame origin, thus the camera pose and the camera intrinsic parameters will be wrong.
