This repository provides two LiDAR degeneracy datasets (tunnel and fog) in ROS bag format, hosted on Hugging Face. It includes detailed metadata about the sensors (IMU, LiDAR, radar), their extrinsics, topics, and rates. The datasets are intended for research in LiDAR-radar-inertial fusion for challenging environments. The repository contains no code for processing the data, only documentation and links to the raw data.
