The focal length marked on the lens is at infinity focus.Focal length will be 2x that if at macro 1:1 focus (but can be slightly different than 2x if lens has internal focusing). Focal length is generally near close enough at the closest focus of a regular lens, but calculations will ...
If for both axes a common focal length is used with a given a aspect ratio (usually 1), then fy=fx∗a and in the upper formula we will have a single focal length f. The matrix containing these four parameters is referred to as the camera matrix. While the distortion coefficients are...
