Planes and epipolar geometry
The homography between two planes is represented by a
matrix
The epipoles are image projections of a 3D point lying on all planes, because the line joining the optical centers intersects any plane.
Four coplanar points and two points off the plane determine the epipolar geometry.
Compute the plane projective transformation
, such that
.
Determine the epipole
in the
image as the intersection of the lines
and
.
The epipolar line in the
image of any other point
is given as
.
