摘要:

传感器类型变化和地理环境差异等域偏移在自动驾驶(AD)中普遍存在,并带来挑战:依赖以往域知识的AD模型若不付出额外成本,几乎无法直接部署到新域。本文通过提出重建-模拟-感知(ReSimAD)方案,为缓解域偏移提供了新视角和方法。具体而言,隐式重建过程基于来自以往旧域的知识,旨在将与域相关的知识转换为域不变表示,例如3D场景级网格。此外,多个新域的点云模拟过程以上述重建的3D网格为条件,由此可获得类似目标域的模拟样本,从而降低后续感知过程中收集和标注新域数据的成本。实验中,我们考虑Waymo-to-KITTI、Waymo-to-nuScenes、Waymo-to-ONCE等不同跨域情形,以验证使用ReSimAD进行零样本目标域感知。结果表明,我们的方法有助于提升域泛化能力,甚至在3D预训练方面也具有前景。

英文摘要:

Domain shifts such as sensor type changes and geographical situation variations are prevalent in Autonomous Driving (AD), which poses a challenge since AD model relying on the previous domain knowledge can be hardly directly deployed to a new domain without additional costs. In this paper, we provide a new perspective and approach of alleviating the domain shifts, by proposing a Reconstruction-Simulation-Perception (ReSimAD) scheme. Specifically, the implicit reconstruction process is based on the knowledge from the previous old domain, aiming to convert the domain-related knowledge into domain-invariant representations, e.g., 3D scene-level meshes. Besides, the point clouds simulation process of multiple new domains is conditioned on the above reconstructed 3D meshes, where the target-domain-like simulation samples can be obtained, thus reducing the cost of collecting and annotating new-domain data for the subsequent perception process. For experiments, we consider different cross-domain situations such as Waymo-to-KITTI, Waymo-to-nuScenes, Waymo-to-ONCE, etc, to verify the zero-shot target-domain perception using ReSimAD. Results demonstrate that our method is beneficial to boost the domain generalization ability, even promising for 3D pre-training.
