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.
3. AI Pipeline Process
Table structure recognition (TSR) detects grid cells while specialized OCR parses door marks, dimensions, fire ratings, and material codes.
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.
6. Business Impact
Eliminates 95% of manual data entry for door manufacturers, estimating teams, and hardware suppliers.
