A Multi-State Constraint Kalman Filter for Vision-aided ...
www-users.cse.umn.edudefined using the epipolar geometry, and combined with IMU measurements in an Extended Kalman Filter (EKF). In [10], [11] the epipolar geometry is employed in conjunction with a statistical motion model, while in [12] epipolar constraints are fused with the dynamical model of an airplane. The use of

This is arguably the best-understood part of stereo vision; we therefore assume in this paper that we are given a pair of rectified images as input. Recent references on stereo camera calibration and rectification include [130, 70, 131, 52, 39]. 2.2. Representation ...

We show that solving for image reconstruction alone re-sults in poor quality depth images. To overcome this problem, we propose a novel training loss that enforces consistency be-

Specifically, in a 2D domain, the spatial consistency only provides a weak relation between points and epipolar lines [13, 9, 73]. Instead, in a 3D domain, the spatial consistency is rigorously defined between every pair of points ...

(b) An image point x back-projects to a ray in 3-space defined by the first camera centre, C, and x. This ray is imaged as a line l′ in the second view. The 3-space pointXwhich projects to xmust lie on this ray, so the image of Xin the second view must ...
