From One to the Power of Many: Augmentations for Invariance to Multi-LiDAR Perception from Single-Sensor Datasets
<|reference_start|>From One to the Power of Many: Augmentations for Invariance to Multi-LiDAR Perception from Single-Sensor Datasets: Recently, LiDAR perception methods for autonomous vehicles, powered by deep neural networks have experienced steep growth in performance on classic benchmarks, such as nuScenes and SemanticKITTI. However, there are still large gaps in performance when deploying models trained on such single-sensor setups to modern multi-sensor vehicles. In this work, we investigate if a lack of invariance may be responsible for these performance gaps, and propose some initial solutions in the form of application-specific data augmentations, which can facilitate better transfer to multi-sensor LiDAR setups. We provide experimental evidence that our proposed augmentations improve generalization across LiDAR sensor setups, and investigate how these augmentations affect the models' invariance properties on simulations of different LiDAR sensor setups.<|reference_end|>
