Focal and principal point change


#1

Hi,

Recently I realize that the focal length and principal points of my Parrot Sequoia have changed.

The old values were; f: 3.98mm, cx: 2.503317 and cy: 1.750155 and now the values are; f: 4.00mm, cx: 2.55107 and cy: 1.742252

Is this relevant? Why do these values changed?

Thanks,

JP
