Spark Anomalygen Usd: Synthetic Data Generation Assets for PCB Inspection

NVIDIA Corporation created the Spark Anomalygen Usd dataset on May 30, 2026. It contains USD (Universal Scene Description) files for a full PCBA (Printed Circuit Board Assembly) scene, including an authored AOI (Automated Optical Inspection) ring-light rig and camera. The USD files are derived from underlying CAD designs and are intended for synthetic data generation rendering.

Use Cases

• Generate synthetic training images for AOI systems based on the described PCBA scene and ring-light rig.
• Benchmark anomaly detection algorithms using rendered data from the provided USD assets.
• Simulate different lighting conditions for PCB inspection using the authored AOI ring-light rig.

Strengths

• Assets are derived from underlying CAD designs, suggesting a basis in engineering specifications.
• Includes a full PCBA scene and an authored AOI ring-light rig, providing a structured environment for rendering.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
