feat: Zero-shot pattern detection pipeline for engineering BOM drawings
Duy
Pipeline: NCC multi-scale (Stage 1) + DINOv2 ViT-S/14 (Stage 2) + structural filters
- Auto-classify templates as simple (outline, e.g. resistor) or complex (e.g. bridge rectifier)
- Simple path: Chamfer pre-filter + hybrid DINOv2 bypass for borderline candidates
- Complex path: dual micro-pass (0deg + 90deg) with DINOv2 derotate=True
- FastAPI web UI with PaceOS-style dashboard
- HuggingFace Spaces Docker deployment ready
Results: Drawing 1 (resistor) 10 detections, Drawing 4 (BR) 4 detections,
Example 1 10 detections, Example 2 4 detections. All 10 unit tests pass.
