OCR & Document Intelligence Use Case

Door Schedule Extraction

Automating door schedule extraction from architectural floor plans using custom computer vision and spatial reasoning.

1. The Problem

Door schedules are tabular drawing sheets listing hundreds of door specifications (height, width, material, frame, fire rating, hardware set). Manually keying this data into ERPs takes hours.

2. Input Drawing

Architectural schedule drawing sheet (A-601) featuring multi-column door schedule tables with abbreviated text and header grids.

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

3. AI Pipeline Process

Table structure recognition (TSR) detects grid cells while specialized OCR parses door marks, dimensions, fire ratings, and material codes.

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

4. Annotated Visual Output

Visual bounding grid over schedule sheet with extracted table cell values highlighted in blue and green.

5. Structured Data Export

Structured JSON array matching every door tag to its exact width, height, thickness, material, frame type, fire rating, and hardware set.

{ "use_case": "Door Schedule Extraction", "status": "success", "confidence_score": 0.984, "extracted_count": 42, "export_formats": ["JSON", "REST_API", "CSV", "EXCEL"] }

6. Business Impact

Eliminates 95% of manual data entry for door manufacturers, estimating teams, and hardware suppliers.

Frequently Asked Questions

What if the door schedule spans multiple pages?

Our pipeline automatically merges multi-page table structures and reconciles duplicate header rows.
