A digital twin of a real intersection can generate LiDAR training data that matches the target location, and a detector trained on it reported 4.8% higher car AP than a model trained on real data, though with more synthetic frames.
The h3d dataset for full-surround 3d multi-object detection and tracking in crowded urban scenes,

High-Fidelity Digital Twins for Bridging the Sim2Real Gap in LiDAR-Based ITS Perception
A digital twin of a real intersection can generate LiDAR training data that matches the target location, and a detector trained on it reported 4.8% higher car AP than a model trained on real data, though with more synthetic frames.
