Are those some type of calibration targets on the side of coring drill?

While I believe you are correct and I don't think they are used for camera calibration, camera intrinsics are known to vary depending on external conditions. Cameras on autonomous ships need regular recalibration for instance.
Yeah I guess a little expansion due to temperature change would wreak havoc on an optical system.
I don't really know how they'd recalibrate the navigation cams in the main body then. The mast and arm cams can look at calibration targets on the rovers back.
I have updated my comment to remove that statement.
