Post-integration based point-line feature visual SLAM in low-texture environments [PDF]

open access: yesScientific Reports
To address the issues of weak robustness and low accuracy of traditional SLAM data processing algorithms in weak texture environments such as low light and low contrast, this paper first studies and improves the data feature extraction method, optimizing

LiDAR Iris for Loop-Closure Detection [PDF]

open access: yes2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020
In this paper, a global descriptor for a LiDAR point cloud, called LiDAR Iris, is proposed for fast and accurate loop-closure detection. A binary signature image can be obtained for each point cloud after several LoG-Gabor filtering and thresholding operations on the LiDAR-Iris image representation.

AirLoop: Lifelong Loop Closure Detection

open access: yes2022 International Conference on Robotics and Automation (ICRA), 2022
Loop closure detection is an important building block that ensures the accuracy and robustness of simultaneous localization and mapping (SLAM) systems. Due to their generalization ability, CNN-based approaches have received increasing attention. Although they normally benefit from training on datasets that are diverse and reflective of the environments,

Loop closure detection using depth images [PDF]

open access: yes2013 European Conference on Mobile Robots, 2013
We investigate the question whether loop closure detection using depth images is feasible using currently available depth features. For this reason, we collected a benchmark dataset consisting of a total number of 15 logfiles with several loops in various environments, implemented a modular and easily extensible loop closure detector and used this to ...

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 ...
