In this study we analyzed deep learning methods for point clouds semantic segmentation. We compared PointNet and PointNet++ on data with different characteristics, coming from distinct domains, in order to understand their behavior. Finally, we exploited the so gained knowledge to improve the performance of the models on railway data. In particular, we properly updated the training protocol and altered the PointNet++ architecture, in order to perform transfer learning by leveraging the models previously trained in the first experiments. Results on both state-of-the-art datasets and on a custom dataset specifically acquired for this scope demonstrate that transfer learning can effectively boost the performance of the models in terms of prediction accuracy and convergence rate in the railway context.

Abstract

In this study we analyzed deep learning methods for point clouds semantic segmentation. We compared PointNet and PointNet++ on data with different characteristics, coming from distinct domains, in order to understand their behavior. Finally, we exploited the so gained knowledge to improve the performance of the models on railway data. In particular, we properly updated the training protocol and altered the PointNet++ architecture, in order to perform transfer learning by leveraging the models previously trained in the first experiments. Results on both state-of-the-art datasets and on a custom dataset specifically acquired for this scope demonstrate that transfer learning can effectively boost the performance of the models in terms of prediction accuracy and convergence rate in the railway context.
