Hi to all, i am developing an iOS app (for iPad) using OpenCV for the ArUco markers detection and pose estimation.
Doing the calibration process, i make an estimation of the calibration matrix (including the focal length).
So my question is: during the pose estimation process, do i need to disable the autofocus?
I am in doubt because i know that if i change the focal length and then i capture an image, the pose is wrong because the image is taken with a different focal.
But on the other hand the autofocus doesn't change really the focal length, isn't? (So it's different for example from the zoom).
I am talking about the autofocus system on the iPad, so not a professional camera and i suppose that the autofocus system is software, i mean it make the lenses move backward and forward, but then the "adjustment" is software, am i wrong? Thanks.
