Recent advancements in 3D Gaussian Splatting (3DGS) have significantly improved the mapping quality and computational efficiency of visual Simultaneous Localization and Mapping (SLAM). We propose DOGL-SLAM, a novel framework that integrates 3DGS into its core pipeline, enabling accurate camera pose
Unmanned aerial vehicles (UAVs) have been widely employed to achieve autonomous exploration of 3D unknown environments. However, most existing algorithms suffer from low exploration efficiency caused by inaccurate motion time cost evaluation, which typically leads to the motion inconsistency during …
This paper proposes R-VoxelMap, a novel voxel mapping method that constructs accurate voxel maps using a geometry-driven recursive plane fitting strategy to enhance the localization accuracy of online LiDAR odometry. VoxelMap and its variants typically fit and check planes using all points in a voxe
Mobile robot motion planning heavily relies on grid-based occupancy maps, while existing works require high memory usage and expensive updating overhead. In this work, we propose a memory-lite grid-block data structure and an efficient map updating algorithm for LiDAR-based online exploration-orient…
Accurate and reliable online real-time localization and mapping are crucial for autonomous navigation of robot. Dynamic objects within the perception field can affect the accuracy of registration and localization, and also introduce ghost trail artifacts in the map, hindering robot planning and deci
Efficient data transmission and reasonable task allocation are important to improve multi-robot exploration efficiency. However, most communication data types typically contain redundant information and thus require massive communication volume. Moreover, exploration-oriented task allocation is far
Ground robot autonomous exploration for uneven terrains is still challenging since the rugged terrain structures not only degrade the exploration performance but also threaten the navigation safety of the robot. In this letter, a novel exploration planner is proposed for safe and fast exploration in
