CT-ICP: Real-time Elastic LiDAR Odometry with Loop Closure [PDF]
IEEE International Conference on Robotics and Automation, 2021 Multi-beam LiDAR sensors are increasingly used in robotics, particularly with autonomous cars for localization and perception tasks, both relying on the ability to build a precise map of the environment.

Improving Self-Consistency in Underwater Mapping Through Laser-Based Loop Closure [PDF]
IEEE Transactions on robotics, 2023 Accurate, self-consistent bathymetric maps are needed to monitor changes in subsea environments and infrastructure. These maps are increasingly collected by underwater vehicles, and mapping requires an accurate vehicle navigation solution. Commercial off-

SA-LOAM: Semantic-aided LiDAR SLAM with Loop Closure [PDF]
IEEE International Conference on Robotics and Automation, 2021 LiDAR-based SLAM system is admittedly more accurate and stable than others, while its loop closure detection is still an open issue. With the development of 3D semantic segmentation for point cloud, semantic information can be obtained conveniently and ...

PADLoC: LiDAR-Based Deep Loop Closure Detection and Registration Using Panoptic Attention [PDF]
IEEE Robotics and Automation Letters, 2022 A key component of graph-based SLAM systems is the ability to detect loop closures in a trajectory to reduce the drift accumulated over time from the odometry.

Autonomous mobile robot with ORB-SLAM 2 [PDF]
, 2021 In this thesis we introduced ORB-SLAM2. It is critical for a mobile robot to be able to identify revisited locations or loop closures while conducting Simultaneous Localization and Mapping (SLAM) in order to be successful during autonomous navigation ...

Loop Closure Prioritization for Efficient and Scalable Multi-Robot SLAM [PDF]
IEEE Robotics and Automation Letters, 2022 Multi-robot SLAM systems in GPS-denied environments require loop closures to maintain a drift-free centralized map. With an increasing number of robots and size of the environment, checking and computing the transformation for all the loop closure ...

Intensity Scan Context: Coding Intensity and Geometry Relations for Loop Closure Detection [PDF]
IEEE International Conference on Robotics and Automation, 2020 Loop closure detection is an essential and challenging problem in simultaneous localization and mapping (SLAM). It is often tackled with light detection and ranging (LiDAR) sensor due to its view-point and illumination invariant properties.
