Floor Plan OCR
Purpose-built optical character recognition designed specifically for noisy, rotated, and hand-annotated text in architectural drawings.
Key Extraction Targets
The Problem
Standard OCR fails catastrophically on architectural plans.
Generic OCR tools expect clean, horizontal paragraphs. Floor plans feature text rotated at 90°, 45°, or arbitrary angles, overlapping line work, abbreviated tags, and tabular schedules.
System Workflow
How the AI System Works
Orientation & Text Angle Detection
Scan drawing for text bounding boxes and estimate rotation angles (0°, 90°, 180°, 270°, or arbitrary).
Bespoke Text Recognition
Run custom-trained OCR tuned on architectural fonts, shorthand, and blueprint symbols.
Spatial Text-to-Element Association
Link text callouts to nearby physical drawing elements (e.g. tag 'D-04' to nearest door arc).
