Radial Distortion from Epipolar Constraint for Rectilinear Cameras

open access: yesJournal of Imaging, 2017
Lens distortion causes difficulties for 3D reconstruction, when uncalibrated image sets with weak geometry are used. We show that the largest part of lens distortion, known as the radial distortion, can be estimated along with the center of distortion ...

KPI‐NeRF: Hyperspectral Neural Radiance Fields from a Single Kaleidoscopic Plenoptic Image

open access: yesComputer Graphics Forum, EarlyView.
KPI‐NeRF reconstructs hyperspectral light field images from a single kaleidoscopic plenoptic image. By leveraging neural radiance fields, it enables high‐quality spectral and angular de‐multiplexing for dynamic scene capture. Abstract Plenoptic imaging has excessive sampling requirements associated with the high dimensionality of the desired data.

HOPIS: Hybrid Omnidirectional and Perspective Imaging System for Mobile Robots

open access: yesSensors, 2014
In this paper, we present a framework for the hybrid omnidirectional and perspective robot vision system. Based on the hybrid imaging geometry, a generalized stereo approach is developed via the construction of virtual cameras. It is then used to rectify

Boosting Embodied Visual Localisation Through Multi‐Granular Semantics and Multi‐Robot Consensus

open access: yesCAAI Transactions on Intelligence Technology, Volume 11, Issue 4, Page 1088-1103, August 2026.
ABSTRACT Achieving high accuracy and synergy remains extremely difficult for multi‐robot embodied visual localisation, which suffers from persistent real‐world challenges such as viewpoint ambiguity, appearance variation and dynamic occlusion. Conventional optimisation‐based methods often lead to incorrect feature matching without domain adaptation ...

Observing Electrical Discharge With High 3D Spatial Resolution

open access: yesHigh Voltage, Volume 11, Issue 4, Page 899-905, August 2026.
ABSTRACT This study introduces an application of binocular stereo vision technology to achieve high‐resolution 3D visualisation of submillimeter discharge channels. The proposed method can capture the depth information of weak luminous discharges and provide 3D discharge trajectories, providing new insights into the discharge mechanism.
