LiDAR Point Cloud Classification by 3D Sparse CNN for large-scale Mobile Laser Scanning
Nan Li, H. Teufelsbauer, Florian Pöppl, Andreas Ullrich
Abstract. Semantic classification is a fundamental step in Mobile Laser Scanning (MLS) point clouds processing, and remains a non-trivial task. In this work, we propose a classification framework based on a 3D Sparse Convolutional Neural Network (SparseCNN) for efficient processi…
