“…With the development of light detection and ranging (LiDAR) technology, mobile laser scanning (MLS) systems, which deploy one or multiple LiDARs on a ground-based vehicle, 1 can quickly collect a high-resolution and high-precision point cloud of the surroundings of the vehicle and have gained increasing attention in three-dimensional (3D) urban scene analysis, 2 including urban 3D modeling 3 and automated urban driving. 4 Classification of MLS point clouds, in which each point in an MLS point cloud is determined to belong to a specific class, e.g., ground, 5 road, 6 road markings, 7 vehicles, 8 power lines, 9 and street trees, 10,11 is a common and core task for various applications of 3D urban scene analysis. 12 Weinmann et al 13 proposed a pointwise classification framework, whereby each individual point is classified by a binary classifier involving a set of local geometric features derived from the neighborhoods of the point.…”
