Text-Symbol Overlap & Readability Risk Analyzer
Preventing construction field errors by flagging obstructed text on engineering blueprints.
The Friction
Large engineering drawings contain dense overlays of text, wire runs, and symbols. When key labels (like dimensions, circuit numbers, or safety notes) overlap with symbols or lines, they become unreadable, causing expensive installation mistakes in the field. Manually auditing drawings for overlap issues is impossible due to scale.
The Neural Architecture
We engineered a hybrid vector-raster overlap analysis engine. It extracts precise text bounding boxes from PDF metadata, performs raster-based overlap detection to measure the degree of line obstruction, and computes a readability risk score (Low, Medium, High). It serves these findings on an interactive web interface for QA inspectors to rapidly review and resolve conflicts.
