Epipolar Geometry and the Fundamental Matrix

Epipolar Geometry and the Fundamental Matrix The epipolar geometry is the intrinsic projective geometry between two views. It is independent of scene structure, and only depends on the cameras’ internal parameters and relative pose. The fundamental matrix Fencapsulates this intrinsic geometry. It is a 3 × 3 matrix of rank 2.
