Two view constraints on the epipoles from few correspondences
In general it requires at least 7 point correspondences to compute the
fundamental matrix between views. We use the cross ratio invariance between
corresponding epipolar lines, stemming from epipolar line homography, to derive
a simple formulation for the relationship between epipoles and corresponding
points. We show how it can be used to reduce the number of required points for
the epipolar geometry when some information about the epipoles is available and
demonstrate this with a buddy search app
Cameras Viewing Cameras Geometry
A basic problem in computer vision is to understand the structure of a
real-world scene given several images of it. Here we study several theoretical
aspects of the intra multi-view geometry of calibrated cameras when all that
they can reliably recognize is each other. With the proliferation of wearable
cameras, autonomous vehicles and drones, the geometry of these multiple cameras
is a timely and relevant problem to study
