SemanticLoop: loop closure with 3D semantic graph matching
Junfeng Yu, Shaojie Shen
Loop closure can effectively correct the accumulated error in robot localization, which plays a critical role in the long-term navigation of the robot. Traditional appearance-based…
SLAM: Decentralized and Distributed Collaborative Visual-inertial SLAM System for Aerial Swarm
Hao Xu, Peize Liu, Xinyi Chen +1
Collaborative simultaneous localization and mapping (CSLAM) is essential for autonomous aerial swarms, laying the foundation for downstream algorithms such as planning and control.…
RACER: Rapid Collaborative Exploration with a Decentralized Multi-UAV System
Boyu Zhou, Hao Xu, Shaojie Shen
Although the use of multiple Unmanned Aerial Vehicles (UAVs) has great potential for fast autonomous exploration, it has received far too little attention. In this paper, we presen…
Fast 3D Sparse Topological Skeleton Graph Generation for Mobile Robot Global Planning
Xinyi Chen, Boyu Zhou, Jiarong Lin +3
In recent years, mobile robots are becoming ambitious and deployed in large-scale scenarios. Serving as a high-level understanding of environments, a sparse skeleton graph is benef…
An Efficient Spatial-Temporal Trajectory Planner for Autonomous Vehicles in Unstructured Environments
Zhichao Han, Yuwei Wu, Tong Li +8
As a core part of autonomous driving systems, motion planning has received extensive attention from academia and industry. However, real-time trajectory planning capable of spatial…
Exploration with Global Consistency Using Real-Time Re-integration and Active Loop Closure
Yichen Zhang, Boyu Zhou, Luqi Wang +1
Despite recent progress of robotic exploration, most methods assume that drift-free localization is available, which is problematic in reality and causes severe distortion of the r…
Neither Fast Nor Slow: How to Fly Through Narrow Tunnels
Luqi Wang, Hao Xu, Yichen Zhang +1
Nowadays, multirotors are playing important roles in abundant types of missions. During these missions, entering confined and narrow tunnels that are barely accessible to humans is…
