πŸš€ News Update (October 22, 2025 - Many More Scenes and Better Ease of Use)!!

We have now:

  • Increased our number of NuRec scenes to 924!!
  • Added labels.json file for helping users who want to search by types of scenes based on: behavior, layout, lighting, road types, surface conditions, traffic density, vrus presence, and weather. (Note this is only available for files under Batch0002 and onwards)
  • A front camera video file for each clips so that users can assess the scene before opening the usdz. (Note this is only available for files under Batch0002 and onwards)

Find the 900+ scenes in the sample_set/25.07_release folder.

Dataset Description:

Neural reconstructed dataset that carries 3D reconstructed driving scenes. The scenes are about 20 second long and stored in form of usdz files, along with respective xodr map files, surface mesh. The reconstructions were generated using 6 camera views (front-wide 120 deg, front-tele 30 deg, cross right/left 120 deg and rear right/left 70 deg). Users can use these 3D reconstructed driving scenes for training and testing their autonomous vehicle (AV) systems. This dataset is ready for commercial/non-commercial AV only use.

Dataset Owner(s):

NVIDIA Corporation

Dataset Creation Date:

06/09/2025

License/Terms of Use:

NVIDIA Autonomous Vehicle Dataset License Agreement

Intended Usage:

This dataset is intended to provide AV developers with the experience of NuRec capability and try out 3DGUT. Users can use this dataset to run a set of tests / experiments for an AV system and train AI models that use camera and reconstructed data. The scenes in this dataset are generated by and can be rendered by using NVIDIA NuRec. CARLA users can also utilize this dataset by which leveraging the NVIDIA NuRec integration in CARLA.

Dataset Characterization

Data Collection Method

  • [Automatic/Sensors] - [Machine-derived]

Labeling Method

  • [Automatic/Sensors] - [Machine-derived]

Dataset Format

The scenes are stored by batches containing a number of clip folders listed by their UUIDs. Each UUID folder contains:

  • usdz file (always)
  • labels.json file (in most cases)
  • camera_front_wide_120fov.mp4 (in most cases)

Each reconstructed scene is stored as a USDZ File containing the following:
