Query: Resultant Based Incremental Recovery of Camera Pose from Pairwise
  Matches   Incremental (online) structure from motion pipelines seek to recover the
camera matrix associated with an image $I_n$ given $n-1$ images,
$I_1,...,I_{n-1}$, whose camera matrices have already been recovered. In this
paper, we introduce a novel solution to the six-point online algorithm to
recover the exterior parameters associated with $I_n$. Our algorithm uses just
six corresponding pairs of 2D points, extracted each from $I_n$ and from
\textit{any} of the preceding $n-1$ images, allowing the recovery of the full
six degrees of freedom of the $n$'th camera, and unlike common methods, does
not require tracking feature points in three or more images. Our novel solution
is based on constructing a Dixon resultant, yielding a solution method that is
both efficient and accurate compared to existing solutions. We further use
Bernstein's theorem to prove a tight bound on the number of complex solutions.
Our experiments demonstrate the utility of our approach.
