Ground-to-Air Robust Robot Vision — perception that keeps working off-road, in adverse weather, and from the air.

• Multi-sensor fusion — LiDAR × Camera × Radar × Thermal (EO/IR)
• 3D perception — object detection & tracking, semantic segmentation, depth completion, traversability estimation
• Robust perception in the wild — off-road / unstructured terrain, adverse weather, domain adaptation
• Efficient deep learning — knowledge distillation, pruning, NAS, quantization for on-device & edge AI
• Physical AI — perception–action models for ground vehicles, UAVs, and field robots

Low-end 3D LiDAR perception  →  Multi-sensor fusion & deep learning  →  Ground-to-Air Robust Robot Vision
