The algorithm considers all possible pairwise combinations of matched
lines. If the intersection of the matched lines is in the image, then
the intersection point is tested to see if it obeys the epipolar
constraint. If so, then these two lines are used to compute the plane
normal (3 DOF) for the surface. If the two projection matrices are
and
, and the plane is
represented by
, and p and p' are points in
the two images, then the linear solution to the plane equation is given by:
