UWB Radar SLAM: An Anchorless Approach in Vision Denied Indoor Environments Open

H. A. G. C. Premachandra, Ran Liu, Chau Yuen, U-Xuan Tan · 2023

LiDAR and cameras are frequently used as sensors for simultaneous\nlocalization and mapping (SLAM). However, these sensors are prone to failure\nunder low visibility (e.g. smoke) or places with reflective surfaces (e.g.\nmirrors). On the o…
