ColoRadar: The direct 3D millimeter wave radar dataset [PDF]
The International Journal of Robotics Research, 2022 This work presents two different forms of dense, high-resolution radar data from two frequency modulated continuous wave radar sensors, along sparse radar pointclouds produced by one of the radar sensors. In addition, all datasets include 3D lidar and inertial measurements, and a lidar-based simultaneous localization and mapping pose estimation. Over 2
