3D Volumetric Point Cloud Streaming and Spatial World Model Sidelink

3DV2X standardizes the real-time compression and transmission of 3D spatial occupancy data between connected vehicles and smart infrastructure, allowing autonomous fleets to share high-fidelity volumetric maps beyond direct sight.

Seeing Around Corners in True 3D Volumetric Depth

2D bounding box telemetry lacks the spatial fidelity required for complex autonomous maneuvers. 3DV2X streams dynamic 3D voxel occupancy grids, allowing trailing vehicles to render invisible road obstacles with millimeter depth accuracy.

Core Engineering Areas

• 3D Volumetric Point Cloud Streaming Protocols — Streaming multi-million-point LiDAR frames over bandwidth-constrained 5.9 GHz radio links.
• Spatial Coordinate Transformation Over V2V — Transforming ego-centric sensor coordinates between moving vehicles into unified global reference frames.
• Dynamic Occupancy Grid Fusion Over Sidelink — Merging probabilistic voxel maps to eliminate blind spots caused by large commercial trucks.
