Camera settings at intrinsic calibration time

Hi everyone,

I am wondering under which settings the camera(s) were set by the time they were calibrated.

For instance, one aspect that is easy to find is the reference resolution of the images taken when calibrating the intrinsics, this is by retrieving intrinsicMatrixReferenceDimensions. Making sure that the principal point is referenced to the by the time resolution used when the calibration was ongoing.

However, recently I saw that there are focusing modes that potentially displace the lens' physical position. Settings like:

• AutoFocusRangeRestriction: none, near, far
• setFocusModeLocked: Locks the lens position at the specified value, and sets the focus mode to a locked state.

My concern lies the impact this focusing lens displacements can have on the intrinsic matrix parameters, like these parameters no longer describe the camera since the lens position has changed.

In simple words, what is the focus 'mode'/'range' the cameras were set when calibrating them for intrnisics?
