LOAM: Lidar Odometry and Mapping in Real-time
ri.cmu.edudrift odometry using a 2-axis lidar moving in 6-DOF. A key advantage of using a lidar is its insensitivity to ambient lighting and optical texture in the scene. Recent developments in lidars have reduced their size and weight. The lidars can be held by a person who traverses an environment [6], or even attached to a micro aerial vehicle [7].

nuScenes: A Multimodal Dataset for Autonomous Driving
openaccess.thecvf.comLidar pointclouds, on the other hand, contain less semantic infor-mation but highly accurate localization in 3D [51]. Further-more the reflectance of lidar is an important feature [40, 51]. However, lidar data is sparse and the range is typically lim-ited to 50-150m. Radar sensors achieve a range of 200-

openaccess.thecvf.comLiDAR is not a discrepancy in depth accuracy, but a poor choice of representations of the 3D information for ConvNet-based 3D object detection systems operating on stereo. Specifically, the LiDAR signal is commonly rep-resented as 3D point clouds [23] or viewed from the top-down “bird’s-eye view” perspective [33], and processed ac-cordingly.
