Towards Robust UAV Tracking in GNSS-Denied Environments: A Multi-LiDAR Multi-UAV Dataset



Project Page   •   Paper   •   Contact Us

We present a novel multi-LiDAR dataset specifically designed for UAV tracking. Our dataset includes data from a spinning LiDAR, two solid-state LiDARs with different Field of View (FoV) and scan patterns, and an RGB-D camera. This diverse sensor suite allows for research on new challenges in the field, including limited FoV adaptability and multi-modality data processing. For a comprehensive list of sequences refer to the paper Towards Robust UAV Tracking in GNSS-Denied Environments: A Multi-LiDAR Multi-UAV Dataset and the project page

Calibration

We provide a ROS package to compute the extrinsic parameters between LiDARs and camera based on GICP. As the OS1 has the largest FOV, it is treated as base reference frame ("base_link") in which all the other point clouds are transformed. For the Avia, Mid-360 and Realsense D435, we integrated the first five frames to increase point cloud density.

To use this package, play teh Calibration rosbag in our dataset:

rosbag play Calibration.bag -l

Then run our calibration launch file:

roslaunch multi_lidar_multi_uav_dataset lidars_extrinsic_computation.launch

The computed extrinsic parameters will appear in the terminal:

OS -> base_link 0 0 0 0 0 0 /os_sensor /base_link 10
Avia -> base_link   0.149354  0.0423582 -0.0524961  3.13419 -3.13908 -3.13281 /avia_frame /base_link 10
Mid360 -> base_link   0.125546 -0.0554536   -0.20206 0.00467344  0.0270294  0.0494959 /mid360_frame /base_link 10
Camera -> base_link -0.172863   0.11895 -0.101785 1.55222 3.11188 1.60982 /camera_depth_optical_frame /base_link 10

Install

The code has been tested on Ubuntu 20.04 with ROS Noetic
