Consistent Distributed Invariant EKF SLAM with Point and Object Features
Mengya Xu, Xianjia Yu, Ha Sier +2
Multi-robot SLAM allows robots to improve their estimates by exchanging map information, but repeated exchanges create unknown correlations between local estimators. Covariance int…
P-POSEMEM: Projective Semantic Memory for Consistent Language Grounding under Pose-Graph Rewrites
Ha Sier, Ali Salmasi, Mengya Xu +5
A robot following language instructions needs its semantic memory to keep naming the same physical object while the SLAM pose graph underneath is optimized, loop-closed and compres…
SAFEVPR: Patch-Based Conformal Verification for Safe Cross-Condition Sequence Visual Place Recognition
Ha Sier, Jiaqiang Zhang, Zhuo Zou +2
Sequence-based visual place recognition (VPR) for SLAM and robot relocalization must decide whether the retrieved top-1 candidate is safe to accept. Conformal prediction is a natur…
Event-based Sensor Fusion and Application on Odometry: A Survey
Jiaqiang Zhang, Xianjia Yu, Ha Sier +2
Event cameras, inspired by biological vision, are asynchronous sensors that detect changes in brightness, offering notable advantages in environments characterized by high-speed mo…
UAV Tracking with Solid-State Lidars:Dynamic Multi-Frequency Scan Integration
Iacopo Catalano, Ha Sier, Xianjia Yu +2
With the increasing use of drones across various industries, the navigation and tracking of these unmanned aerial vehicles (UAVs) in challenging environments (such as GNSS-denied e…
UAV Tracking with Lidar as a Camera Sensors in GNSS-Denied Environments
Ha Sier, Xianjia Yu, Iacopo Catalano +3
LiDAR has become one of the primary sensors in robotics and autonomous system for high-accuracy situational awareness. In recent years, multi-modal LiDAR systems emerged, and among…
