4D iRIOM: 4D Imaging Radar Inertial Odometry and Mapping
RA-L 2023
Millimeter wave radar can measure distances, directions, and Doppler velocity for objects in harsh conditions such as fog. The 4D imaging radar with both vertical and horizontal data resembling an image can also measure objects' height. Previous studies have used 3D radars for ego-motion estimation.
