In this article, a full radar based graph SLAM system is proposed for reliable localization and mapping in large-scale environments, which is composed of pose tracking, local mapping, loop closure detection and pose graph optimization, enhanced by novel feature matching and probabilistic point cloud generation.
Abstract
Numerous Simultaneous Localization and Mapping (SLAM) algorithms have been presented in last decade using different sensor modalities. However, robust SLAM in extreme weather conditions is still an open research problem. In this paper, RadarSLAM, a full radar based graph SLAM system, is proposed for reliable localization and mapping in large-scale environments. It is composed of pose tracking, local mapping, loop closure detection and pose graph optimization, enhanced by novel feature matching and probabilistic point cloud generation on radar images. Extensive experiments are conducted on a public radar dataset and several self-collected radar sequences, demonstrating the state-of-the-art reliability and localization accuracy in various adverse weather conditions, such as dark night, dense fog and heavy snowfall.

Do We Need to Compensate for Motion Distortion and Doppler Effects in Spinning Radar Navigation

TL;DR: The conclusion is that both motion distortion and the Doppler effect are significant in different aspects of spinning radar navigation, with the former more prominent than the latter.

RaLL: End-to-End Radar Localization on Lidar Map Using Differentiable Measurement Model

TL;DR: Li et al. as discussed by the authors proposed an end-to-end deep learning framework for radar localization on Lidar Map (RaLL) to bridge the gap, which not only achieves the robust radar localization but also exploits the mature lidar mapping technique, thus reducing the cost of radar mapping.

Scan Context++: Structural Place Recognition Robust to Rotation and Lateral Variations in Urban Environments

TL;DR: In this article , the authors proposed a structural place recognition method based on structural appearance, namely from range sensors, which is robust to both rotation (heading) and translation when roll pitch motions are not severe.

Do We Need to Compensate for Motion Distortion and Doppler Effects in Spinning Radar Navigation

TL;DR: In this paper, a lightweight estimator that can recover the motion between a pair of radar scans while accounting for both motion distortion and Doppler effect is presented. But the authors do not consider the impact of these distortions on radar odometry using the Oxford Radar RobotCar dataset.

Are We Ready for Radar to Replace Lidar in All-Weather Mapping and Localization?

TL;DR: In this paper , an extensive comparison between three topometric localization systems: radar-only, lidar-only and a cross-modal radar-to-lidar system across varying seasonal and weather conditions using the Boreas dataset is presented.

Random sample consensus: a paradigm for model fitting with applications to image analysis and automated cartography

TL;DR: New results are derived on the minimum number of landmarks needed to obtain a solution, and algorithms are presented for computing these minimum-landmark solutions in closed form that provide the basis for an automatic system that can solve the Location Determination Problem under difficult viewing.

Speeded-Up Robust Features (SURF)

TL;DR: A novel scale- and rotation-invariant detector and descriptor, coined SURF (Speeded-Up Robust Features), which approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.

Method for registration of 3-D shapes

TL;DR: In this paper, the authors describe a general purpose representation independent method for the accurate and computationally efficient registration of 3D shapes including free-form curves and surfaces, based on the iterative closest point (ICP) algorithm, which requires only a procedure to find the closest point on a geometric entity to a given point.
