 This paper introduces a new 3D point cloud classification benchmark data set consisting of over 4 billion manually labeled points. The authors also present submissions from the first participants using deep convolutional neural networks, CNNs. These submissions demonstrate significant improvement over existing state-of-the-art methods, suggesting that the data set can help unlock the full potential of deep learning methods for 3D labeling tasks.
