lets say I have the same camera shooting images will a setting without auto focus have different intrinsic parameters than of when auto focus is on?
please do leave some reference :)
Hi, Intrinsic parameter are related to focal and lens. Focal changes correspond to "zoom" changes (so it is not modified during auto-focus), while optic center correspond to lens alignment. And during focus, lens will move, but if the lens are perfect, they will not change the optic center. On chip camera, a small change can occur, but you can, most of the time, neglect the changes as they will be very (very) small!
You can find a good introduction in opencv doc : http://docs.opencv.org/master/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html
