Recently, 4D millimetre-wave radar exhibits more stable perception ability than LiDAR and camera under adverse conditions (e.g. rain and fog). However, low-quality radar points hinder its application, especially the odometry task that requires a dense and accurate matching. To fully explore the pote
Accurate point cloud information is important for robot perception and autonomous driving. Although advanced 4D radar can provide point cloud with higher resolution than 3D radar, its data still contains a significant amount of noise due to measurement principle. To solve this issue, we propose RDN
Vehicle localization is a critical component in the planning and navigation of autonomous driving system. Generally, traditional vehicle localization methods rely on the Global Navigation Satellite System (GNSS) for self-localization. Unfortunately, GNSS can become unreliable and may fail in urban c
In complex indoor structural scenes such as shopping centers and malls, camera pose estimation using pure point features is easy to fail due to the difficulty in extracting sufficient and stable point features from weak textures or dynamic environments. Recent works have attempted to address these c…
In recent years, the interest in underwater exploration with Autonomous Underwater Vehicles (AUVs) equipped with side-scan sonars (SSS) has grown considerably. However, state-of-the-art SSS Simultaneous Localization and Mapping (SLAM) systems encounter challenges in data association across large vie…
In the field of autonomous driving and mobile robotics, constructing high-precision prior maps is a significant problem. For large outdoor scenes, maps often need to be segmented or collected repeatedly. Issues such as sensor degradation and measurement error can result in map inconsistencies or loc
In the process of urban environment mapping, the sequential accumulations of dynamic objects will leave a large number of traces in the map. These traces will usually have bad influences on the localization accuracy and navigation performance of the robot. Therefore, dynamic objects removal plays an…
