论文摘要
为了训练一个表现良好的神经网络进行语义细分，至关重要的是，拥有一个具有可用地面真相的大型数据集以使网络对看不见的数据进行概括。在本文中，我们提出了新颖的点云增强方法，以人为地使数据集多样化。我们以传感器为中心的方法保持数据结构与LIDAR传感器功能一致。由于这些新方法，我们能够通过高价值实例丰富低价值数据，并创建全新的场景。我们使用公共Semantickitti数据集验证了在多个神经网络上的方法，并证明与各自的基线相比，所有网络都会有所改善。此外，我们表明我们的方法能够使用非常小的数据集，节省注释时间，培训时间和相关成本。
To train a well performing neural network for semantic segmentation, it is crucial to have a large dataset with available ground truth for the network to generalize on unseen data. In this paper we present novel point cloud augmentation methods to artificially diversify a dataset. Our sensor-centric methods keep the data structure consistent with the lidar sensor capabilities. Due to these new methods, we are able to enrich low-value data with high-value instances, as well as create entirely new scenes. We validate our methods on multiple neural networks with the public SemanticKITTI dataset and demonstrate that all networks improve compared to their respective baseline. In addition, we show that our methods enable the use of very small datasets, saving annotation time, training time and the associated costs.
