Directionally Constrained Fully Convolutional Neural Network For Airborne Lidar Point Cloud Classification

1 code implementation19 Aug 2019 Congcong Wen, Lina Yang, Ling Peng, Xiang Li, Tianhe Chi

In this paper, we proposed a directionally constrained fully convolutional neural network (D-FCN) that can take the original 3D coordinates and LiDAR intensity as input; thus, it can directly apply to unstructured 3D point clouds for semantic labeling.
