 **Asset Harvester** is an image-to-3D model and end-to-end system that converts sparse, in-the-wild object observations from real driving logs into complete, simulation-ready assets. The model generates 3D assets from a single image or multiple images of vehicles, VRUs or other road objects extracted from autonomous driving sessions.  To run Asset Harvester, please check our [**codebase**](https://github.com/NVIDIA/asset-harvester).
