Loop Closure Detection in Closed Environments [PDF]

open access: yes2019 European Conference on Mobile Robots (ECMR), 2019
Low cost robots, such as vacuum cleaners or lawn mowers employ simplistic and often random navigation policies. Although a large number of sophisticated mapping and planning approaches exist, they require additional sensors like LIDAR sensors, cameras or time of flight sensors.

A Real‐Time and Fast LiDAR–IMU–GNSS SLAM System with Point Cloud Semantic Graph Descriptor Loop‐Closure Detection

open access: yesAdvanced Intelligent Systems, 2023
Herein, a real‐time, fast, tightly coupled simultaneous localization and mapping (SLAM) system is proposed. The deep neural network is used to segment the point cloud semantically to construct the point cloud semantic map descriptor, and the global ...

A Robust and Efficient Loop Closure Detection Approach for Hybrid Ground/Aerial Vehicles

open access: yesDrones, 2023
Frequent and dramatic viewpoint changes make loop closure detection of hybrid ground/aerial vehicles extremely challenging. To address this issue, we present a robust and efficient loop closure detection approach based on the state-of-the-art ...

Loop Closure Detection Based on Differentiable Manifold

open access: yesMobile Information Systems, 2022
Loop closure detection is an important part of SLAM (simultaneous location and mapping), which can effectively reduce the cumulative error of the system after long period of exploration. The existing loop closure detection methods are mainly to evenly distribute the accumulated error in the robot trajectory, but the motion error of the actual robot is ...

A Semantic Topology Graph to Detect Re-Localization and Loop Closure of the Visual Simultaneous Localization and Mapping System in a Dynamic Environment

open access: yesSensors, 2023
Simultaneous localization and mapping (SLAM) plays a crucial role in the field of intelligent mobile robots. However, the traditional Visual SLAM (VSLAM) framework is based on strong assumptions about static environments, which are not applicable to ...

FastLCD: A fast and compact loop closure detection approach using 3D point cloud for indoor mobile mapping

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
In simultaneous localization and mapping (SLAM), loop closure detection is a significant yet still open problem. It contributes to construct a globally consistent and accurate map.

Detecting Loop Closure with Scene Sequences

open access: yesInternational Journal of Computer Vision, 2007
This paper is concerned with "loop closing" for mobile robots. Loop closing is the problem of correctly asserting that a robot has returned to a previously visited area. It is a particularly hard but important component of the Simultaneous Localization and Mapping (SLAM) problem.

Learning to detect loop closure from range data

open access: yes2009 IEEE International Conference on Robotics and Automation, 2009
Despite significant developments in the Simultaneous Localisation and Mapping (SLAM) problem, loop closure detection is still challenging in large scale unstructured environments. Current solutions rely on heuristics that lack generalisation properties, in particular when range sensors are the only source of information about the robot's surrounding ...

Cross-scene loop-closure detection with continual learning for visual simultaneous localization and mapping

open access: yesInternational Journal of Advanced Robotic Systems, 2021
Humans maintain good memory and recognition capability of previous environments when they are learning about new ones. Thus humans are able to continually learn and increase their experience. It is also obvious importance for autonomous mobile robot. The
