Abstract
We consider the problem of auto-calibrating the intrinsic
parameters of a camera moving with a special motion: the
rotation axis of the camera being perpendicular to its translation
direction. Our method for calibrating the camera is
based on Kruppa’s equation which in general requires solving
a set of nonlinear equations. We prove in a theorem how
to recover the true scale of the Kruppa’s equation from the
eigenvalues of a matrix formed using the fundamental matrix
between two views.
