NVIDIA Omniverse NuRec：跨车辆平台扩展自动驾驶感知
原标题：Scale AV Perception Across Vehicle Platforms with NVIDIA Omniverse NuRec
AI 摘要
NVIDIA 发布了 Omniverse NuRec 技术，用于跨车辆平台扩展自动驾驶感知系统。该技术利用 3D 高斯泼溅重建真实驾驶场景，并渲染目标车辆配置的新相机视图，使开发者无需为每个车型收集和标注新数据集即可适配感知模型。教程展示了从重建场景、渲染目标视图到训练感知模型的完整流程，并提供了包含 1500 多个场景的 Physical AI NuRec 数据集。

A perception stack is shaped by the vehicle that carries it. Move the same software to a new carline—for example, from an SUV to a sedan or another vehicle variant in the portfolio—and its perception of the world changes. The sensor placement, calibration, fields of view, occlusions, body geometry, timing, and coverage all shift. A traffic light may appear in a different part of the frame. A curb can become harder to see. A pedestrian near the edge of coverage may become ambiguous. As an autonom
