Epipolar-Constrained Cross-Attention for Triangulation-Guided Depth Estimation From Multi-View Images

IEEE Access
Back Projection, a fundamental process in 3D reconstruction, requires depth information to restore 2D pixels to 3D coordinates. However, since depth information is lost during the projection of 3D space onto a 2D plane, accurate reconstruction is ...

Assessing the Visual SLAM Performance in Autonomous Mobile Robots Using Adaptive GMapping and Cartography

Journal of Engineering, Volume 2026, Issue 1, 2026.
Simultaneous localization and mapping (SLAM) plays a vital role in the operation of autonomous robots. In a dynamic environment, the results of some commonly used SLAM algorithms may not be optimal. Therefore, Visual SLAM is used. This study presents a comparative study of SLAM algorithms for autonomous mobile robots in structured indoor environments ...

A Novel Stereo Matching Algorithm for Tunnel Reconstruction Based on Improved Census‐SAD Fusion and Gradient Information

Journal of Sensors, Volume 2026, Issue 1, 2026.
The presence of weak texture and salt‐and‐pepper noise in tunnel images poses significant challenges to the accuracy of stereo matching. Existing methods have prominent drawbacks: Fixed‐window designs fail to balance weak‐texture smoothing and texture‐rich detail preservation, over‐reliance on central pixels leads to poor noise resistance, insufficient

Cheirality in Epipolar Geometry

, 2001
The image points in two images satisfy epipolar constraint. However, not all sets of points satisfying epipolar constraint correspond to any real geometry because there can exist no cameras and scene points projecting to given image points such that all ...

Hierarchical mussel farm reconstruction from video with object tracking

Journal of the Royal Society of New Zealand, Volume 55, Issue 6, Page 1563-1588, December 2025.
ABSTRACT As the mussel farming industry expands, particularly in regions such as New Zealand, there is a growing need for advanced monitoring and management solutions to ensure sustainability and operational efficiency. The current reliance on manual infrequent observation of aquaculture structures limits farmers' ability to monitor them in real time ...
