Custom AI Use Case

Custom Symbol Detection

Automating custom symbol detection from architectural floor plans using custom computer vision and spatial reasoning.

1. The Problem

Generic AI models only recognize standard doors or windows and completely fail on trade-specific or proprietary company drawing legends.

2. Input Drawing

Trade drawing PDFs containing custom electrical, plumbing, metalwork, or security legend symbols.

INPUT FORMATS: PDF (Vector / Raster) · DWG Renders · TIFF / PNG Scans

3. AI Pipeline Process

We train custom object detection neural networks on your legend icons and sample plan sets to achieve high recall and precision.

Phase 01: Object Detection
Phase 02: 360° Rotated OCR
Phase 03: Spatial Graph Linking

4. Annotated Visual Output

Visual legend overlay highlighting all matched proprietary symbols with bounding boxes and legend key labels.

5. Structured Data Export

JSON array detailing every detected custom symbol type, count, page number, and x/y spatial coordinates.

{ "use_case": "Custom Symbol Detection", "status": "success", "confidence_score": 0.984, "extracted_count": 42, "export_formats": ["JSON", "REST_API", "CSV", "EXCEL"] }

6. Business Impact

Enables specialized subcontractors and equipment manufacturers to automate proprietary product takeoff and quoting.

Frequently Asked Questions

Can the model detect rotated custom symbols?

Yes. Our data augmentation pipeline trains the vision model to detect symbols at all 360° orientations.
