🌍 OccOoD

Out-of-Distribution 3D Semantic Occupancy Prediction

 

💡 What makes OOD evaluation hard? Real-world anomalies are too rare to collect at scale.
💡 Our answer: A Synthetic Anomaly Integration Pipeline that inserts physically-plausible OOD objects into existing 3D occupancy data — producing 3 benchmark datasets spanning 26 anomaly categories.

🧪 Pipeline

Problem	OOD object data is scarce — real anomalies are rare and annotation is expensive
Solution	Synthetic anomaly generation under physical & environmental constraints
Result	Plausible, challenging OOD evaluation data at scale
