4 results3-D Positioning and Environment Mapping for mmWave Communication Systems
Jie Yang, Shi Jin, Chao-Kai Wen +2
The paper develops a 3‑D joint positioning, velocity estimation, and environment mapping (SLAM) framework for millimeter‑wave cloud radio access networks, using hybrid delay‑angle…
Free-Space Features: Global Localization in 2D Laser SLAM Using Distance Function Maps
Alexander Millane, Helen Oleynikova, Juan Nieto +2
The paper proposes a global localization method for 2D lidar SLAM that uses distance function maps to represent both surface and free-space geometry, introducing a new free-space f…
Unsupervised Learning of Depth and Deep Representation for Visual Odometry from Monocular Videos in a Metric Space
Xiaochuan Yin, Chengju Liu
The paper presents DFO, a direct feature odometry framework that unsupervisedly learns depth and hierarchical feature representations from monocular video using metric distances an…
Degeneracy in Self-Calibration Revisited and a Deep Learning Solution for Uncalibrated SLAM
Bingbing Zhuang, Quoc-Huy Tran, Pan Ji +3
The paper analyzes why self‑calibrating radial distortion from two‑view geometry is ambiguous with scene depth, and introduces a CNN trained on synthetic data to estimate camera in…
