Complex Geodesic Curvature for Real-Time LiDAR Feature Classification

by Kemeng Li, Xianghui Chen, Jiangbo Yu, Yijin Chen

ABSTRACT: Conventional point-based algorithms largely ignore the strict sequential order of rotating multi-beam Light Detection and Ranging (LiDARs). We exploit this intrinsic structure by modeling each...
