LiDAR Point Cloud Classification by 3D Sparse CNN for large-scale Mobile Laser Scanning
This work proposes a classification framework based on a 3D Sparse Convolutional Neural Network (SparseCNN) for efficient processing of large-scale MLS data, and shows that radiometric features are critical for distinguishing material dependent classes, such as traffic signs.
