Affine Correspondences in Stereo Vision: Theory, Practice, and Limitations
Levente Hajder
Affine transformations have been recently used for stereo vision. They can be exploited in various computer vision application, e.g., when estimating surface normals, homographies,…
A Unified Formula for Affine Transformations between Calibrated Cameras
Levente Hajder
In this technical note, we derive a closed-form expression for the affine transformation mapping local image patches between two calibrated views. We show that the transformation i…
Robust and Real-time Surface Normal Estimation from Stereo Disparities using Affine Transformations
Csongor Csanad Kariko, Muhammad Rafi Faisal, Levente Hajder
This work introduces a novel method for surface normal estimation from rectified stereo image pairs, leveraging affine transformations derived from disparity values to achieve fast…
Finding Geometric Models by Clustering in the Consensus Space
Daniel Barath, Denys Rozumny, Ivan Eichhardt +2
We propose a new algorithm for finding an unknown number of geometric models, e.g., homographies. The problem is formalized as finding dominant model instances progressively withou…
Pose Estimation for Vehicle-mounted Cameras via Horizontal and Vertical Planes
Istan Gergo Gal, Daniel Barath, Levente Hajder
We propose two novel solvers for estimating the egomotion of a calibrated camera mounted to a moving vehicle from a single affine correspondence via recovering special homographies…
Automatic Estimation of Sphere Centers from Images of Calibrated Cameras
Levente Hajder, Tekla Tóth, Zoltán Pusztai
Calibration of devices with different modalities is a key problem in robotic vision. Regular spatial objects, such as planes, are frequently used for this task. This paper deals wi…
Relative planar motion for vehicle-mounted cameras from a single affine correspondence
Levente Hajder, Daniel Barath
Two solvers are proposed for estimating the extrinsic camera parameters from a single affine correspondence assuming general planar motion. In this case, the camera movement is con…
Least-squares Optimal Relative Planar Motion for Vehicle-mounted Cameras
Levente Hajder, Daniel Barath
A new closed-form solver is proposed minimizing the algebraic error optimally, in the least-squares sense, to estimate the relative planar motion of two calibrated cameras. The mai…
A Minimal Solution for Two-view Focal-length Estimation using Two Affine Correspondences
Daniel Barath, Tekla Toth, Levente Hajder
A minimal solution using two affine correspondences is presented to estimate the common focal length and the fundamental matrix between two semi-calibrated cameras - known intrinsi…
