Neural Reconstruction for AV Simulation
Real world data collected from AV fleets is crucial for AV workflows, but collecting and annotating data for rare events is challenging. NVIDIA offers neural reconstruction tools to create high-fidelity digital twins using existing fleet data, enabling simulation of new events and rendering sensor datasets from different perspectives.
NVIDIA NuRec
NVIDIA NuRec provides APIs and tools for neural reconstruction and rendering, allowing developers to prepare and process sensor data, reconstruct it into 3D representations, and perform rendering for simulation purposes. NuRec data toolkits, ingestion libraries, and containers are available via Voxel51’s toolchain for developers to create 3D digital twins from their datasets.
CARLA Open Source AV Simulator
CARLA is a popular open source simulation platform for AV research, with over 150,000 active developers. NVIDIA is integrating NuRec rendering APIs and Cosmos Transfer-1 world foundation model into CARLA for enhanced simulation capabilities.
Novel View Generation with NuRec Fixer
NuRec Fixer is a transformer-based model that resolves reconstruction artifacts when rendering scenes from novel perspectives. It fills gaps in reconstructions to eliminate visual inconsistencies.
NVIDIA Physical AI Dataset
Developers can experiment with NVIDIA’s open source Physical AI Dataset, which includes data for modeling weather effects, lighting variations, and procedural 3D content generation. This dataset supports training and testing of AV simulation pipelines.
Cosmos World Foundation Models
NVIDIA’s Cosmos WFMs—Reason, Predict, and Transfer—are trained on massive datasets for general understanding and prediction tasks. Cosmos Transfer is a diffusion-based generative model that allows developers to generate different scene variants based on input prompts and sensor data.
Omniverse Blueprint for AV Simulation
The upcoming Omniverse Blueprint for AV Simulation will empower developers to enhance their simulators with neurally reconstructed scenes, synthetic actors, physics modeling, and physically-based rendering. This tool will accelerate AV development workflows for organizations like Foretellix, MathWorks, CARLA, and Mcity.
By leveraging NuRec, Cosmos Transfer, and other NVIDIA tools, developers can advance their AV simulation capabilities and address complex challenges in autonomous vehicle development. Dive into the resources provided to kickstart your AV projects today.
