Method for camera motion parameter estimation from a small number of corresponding points using quaternions [PDF]
Компьютерная оптика, 2020 In this paper, we study methods for determining parameters of camera movement from a set of corresponding points. Unlike the traditional approach, the corresponding points in this paper are not used to determine the fundamental matrix, but directly to ...

IEEE transactions on intelligent transportation systems (Print), 2022 Motion estimation of surrounding objects is indispensable to any mobile machinery. The paper proposes a method to solve the estimation and reconstruction problem of dynamic objects with a mono camera. Using the relative camera motion and detected rigidly

QUASI-EPIPOLAR RESAMPLING OF HIGH RESOLUTION SATELLITE STEREO IMAGERY FOR SEMI GLOBAL MATCHING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Semi-global matching is a well-known stereo matching algorithm in photogrammetric and computer vision society. Epipolar images are supposed as input of this algorithm.

Discrete Epipolar Geometry [PDF]
, 2005 The epipolar geometry, which lies in the basis of 3D reconstruction techniques in the field of computer vision, is formulated in continuous spaces and gives geometric relationships between different views of a point in space. In applications, however, we cannot deal with points themselves in digital images.

On the Probabilistic Epipolar Geometry [PDF]
Procedings of the British Machine Vision Conference 2004, 2004 In this paper, we are going to answer the following question: assuming that we have estimates for the epipolar geometry and its uncertainty between two views, how probable is it that a new, independent point pair will satisfy the true epipolar geometry and be, in this sense, a feasible candidate correspondence pair?

Triplet Epipolar Images for Spaceborne Three Linear Cameras [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesEpipolar images can reduce conjugate points searching from a two-dimensional to a one-dimensional space, which significantly improves the robustness and efficiency of dense matching.

EPINET: A Fully-Convolutional Neural Network Using Epipolar Geometry for Depth from Light Field Images [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018 Light field cameras capture both the spatial and the angular properties of light rays in space. Due to its property, one can compute the depth from light fields in uncontrolled lighting environments, which is a big advantage over active sensing devices ...

CALIBRATION AND EPIPOLAR GEOMETRY OF GENERIC HETEROGENOUS CAMERA SYSTEMS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 The application of perspective camera systems in photogrammetry and computer vision is state of the art. In recent years nonperspective and especially omnidirectional camera systems were increasingly used in close-range photogrammetry tasks. In general

Epipolar Geometry for the Rectification of Cubic Panoramas [PDF]
The 3rd Canadian Conference on Computer and Robot Vision (CRV'06), 2006 Image panoramas are of importance for virtual navigation in remote or synthetic environments. To process these panoramas, different representations have been proposed; this paper presents a study of cubic panoramas. Standard projective geometry concepts are adapted to cubic panoramas to derive the notions of fundamental matrix, essential matrix and the
