CSMapping: Scalable Crowdsourced Semantic Mapping and Topology Inference for Autonomous Driving
Zhijian Qiao, Zehuan Yu, Tong Li +3
Crowdsourcing enables scalable autonomous driving map construction, but low-cost sensor noise hinders quality from improving with data volume. We propose CSMapping, a system that p…
SLIM: Scalable and Lightweight LiDAR Mapping in Urban Environments
Zehuan Yu, Zhijian Qiao, Wenyi Liu +2
LiDAR point cloud maps are extensively utilized on roads for robot navigation due to their high consistency. However, dense point clouds face challenges of high memory consumption…
Speak the Same Language: Global LiDAR Registration on BIM Using Pose Hough Transform
Zhijian Qiao, Haoming Huang, Chuhao Liu +4
Light detection and ranging (LiDAR) point clouds and building information modeling (BIM) represent two distinct data modalities in the fields of robot perception and construction.…
SLABIM: A SLAM-BIM Coupled Dataset in HKUST Main Building
Haoming Huang, Zhijian Qiao, Zehuan Yu +4
Existing indoor SLAM datasets primarily focus on robot sensing, often lacking building architectures. To address this gap, we design and construct the first dataset to couple the S…
G3Reg: Pyramid Graph-based Global Registration using Gaussian Ellipsoid Model
Zhijian Qiao, Zehuan Yu, Binqian Jiang +2
This study introduces a novel framework, G3Reg, for fast and robust global registration of LiDAR point clouds. In contrast to conventional complex keypoints and descriptors, we ext…
