3D Reconstruction Problem Given points correspondences from left and right images, we need to construct their 3D positions in the real worlds coordinates. Three cases of 3D reconstruction depending on the amount of a priori knowledge on the stereo system:- Both intrinsic and extrinsic known - > can solve the reconstruction problem unambiguously by triangulation Only intrinsic known -> recovery structure and extrinsic up to an unknown scaling factor Only correspondences -> reconstruction only up to an unknown, global projective transformation
