LiDAR Teach, Radar Repeat: Robust Cross-Modal Navigation in Degenerate and Varying Environments
Renxiang Xiao, Yichen Chen, Yuanfan Zhang +5
Long-term autonomy requires robust navigation in environments subject to dynamic and static changes, as well as adverse weather conditions. Teach-and-Repeat (T\&R) navigation offer…
EFEAR-4D: Ego-Velocity Filtering for Efficient and Accurate 4D radar Odometry
Xiaoyi Wu, Yushuai Chen, Zhan Li +2
Odometry is a crucial component for successfully implementing autonomous navigation, relying on sensors such as cameras, LiDARs and IMUs. However, these sensors may encounter chall…
LiV-GS: LiDAR-Vision Integration for 3D Gaussian Splatting SLAM in Outdoor Environments
Renxiang Xiao, Wei Liu, Yushuai Chen +1
We present LiV-GS, a LiDAR-visual SLAM system in outdoor environments that leverages 3D Gaussian as a differentiable spatial representation. Notably, LiV-GS is the first method tha…
Get It For Free: Radar Segmentation without Expert Labels and Its Application in Odometry and Localization
Siru Li, Ziyang Hong, Yushuai Chen +2
This paper presents a novel weakly supervised semantic segmentation method for radar segmentation, where the existing LiDAR semantic segmentation models are employed to generate se…
