AI总结:

ViGT是一种用于自动驾驶的几何模型,通过自监督训练估计连续3D占用场,实现跨不同传感器配置的泛化和可扩展性。

摘要:

我们介绍了视觉隐式几何变换器(ViGT),一种自动驾驶几何模型,能够从环绕视图相机系统中估计连续的3D占用场。ViGT代表了自动驾驶基础几何模型的一个进展,优先考虑可扩展性、架构简洁性和在不同传感器配置下的泛化能力。我们的方法通过无校准架构实现这一点,使单一模型能够适应不同的传感器设置。与专注于像素对齐预测的一般用途几何基础模型不同,ViGT在鸟瞰图(BEV)域内估计连续的3D占用场,以满足领域特定需求。ViGT自然地从多个摄像头视图推断几何到单一度量坐标框架,为多个几何任务提供共同的表示。与大多数现有占用模型不同,我们采用自监督训练程序,利用同步的图像-激光雷达对,消除了对昂贵手动注释的需求。我们通过在五个大规模自动驾驶数据集(NuScenes、Waymo、NuPlan、ONCE和Argoverse)的混合上训练模型,验证了我们方法的可扩展性和泛化能力,并在点图估计任务中实现了最先进的性能,最佳的平均排名在所有评估基线中。我们进一步在Occ3D-nuScenes基准上评估ViGT,其中ViGT在监督方法中实现了可比的性能。源代码可在https://github.com/whesense/ViGT上公开获取。

英文摘要:

We introduce the Visual Implicit Geometry Transformer (ViGT), an autonomous driving geometric model that estimates continuous 3D occupancy fields from surround-view camera rigs. ViGT represents a step towards foundational geometric models for autonomous driving, prioritizing scalability, architectural simplicity, and generalization across diverse sensor configurations. Our approach achieves this through a calibration-free architecture, enabling a single model to adapt to different sensor setups. Unlike general-purpose geometric foundational models that focus on pixel-aligned predictions, ViGT estimates a continuous 3D occupancy field in a birds-eye-view (BEV) addressing domain-specific requirements. ViGT naturally infers geometry from multiple camera views into a single metric coordinate frame, providing a common representation for multiple geometric tasks. Unlike most existing occupancy models, we adopt a self-supervised training procedure that leverages synchronized image-LiDAR pairs, eliminating the need for costly manual annotations. We validate the scalability and generalizability of our approach by training our model on a mixture of five large-scale autonomous driving datasets (NuScenes, Waymo, NuPlan, ONCE, and Argoverse) and achieving state-of-the-art performance on the pointmap estimation task, with the best average rank across all evaluated baselines. We further evaluate ViGT on the Occ3D-nuScenes benchmark, where ViGT achieves comparable performance with supervised methods.
