Multiview Stereo with Cascaded Epipolar RAFT

Stereo and Multiview Geometry

Narrow Baseline Glsl Multiview Stereo

Our ultimate goal is a system capable of on-line 3D reconstruction from a monocular video and running on commodity hardware. One intrinsic module in such a system is a fast stereo algorithm, which produces depth maps from given views with known camera calibration and pose. Plane-sweep stereo algorithms are well-suited for real-time GPU implementation and can easily be generalised to true multi-...

Fish-Eye-Stereo Calibration and Epipolar Rectification

The paper describes calibration and epipolar rectification for stereo with fish-eye optics. While stereo processing of classical cameras is state of the art for many applications, stereo with fish-eye cameras have been much less discussed in literature. This paper discusses the geometric calibration and the epipolar rectification as prerequisite for stereo processing with fish-eyes. First, it s...

Occlusions, Discontinuities, and Epipolar Lines in Stereo

Binocular stereo is the process of obtaining depth information from a pair of left and right views of a scene. We present a new approach to compute the disparity map by solving a global optimization problem that models occlusions, discontinuities, and epipolar-line interactions. In the model, geometric constraints require every disparity discontinuity along the epipolar line in one eye to alway...

On the Epipolar Geometry in Stereo Vision

In this paper we are interested in the calculation of the equation governing pairs of epipolar lines for unregistered images, i.e. when the image acquisition parameters are unknown or no calibration object is available. First we do a thorough analysis of the mathematics required to nd the epipolar line equations in the classical sense. Thereafter we show that for a broad class of stereo images ...
