Overview
YOLO11x model trained to detect structural elements inside blueprint legends on architectural and construction drawings.
- Detects legend symbols (hatch patterns and graphical symbols).
- Detects legend descriptions.
- Detects complete legend rows.
- Detects legend continuation blocks.
- Trained on architectural floor plans and construction drawings.
Classes
| ID | Class | Purpose |
|---|---|---|
| 0 | legend_symbol | Graphical symbol or hatch pattern representing a construction element or material. |
| 1 | legend_description | Text description corresponding to a legend symbol. |
| 2 | legend_row | Complete legend entry containing a symbol and its associated description. |
| 3 | legend_continuation_block | A block containing the continuous legend elements. |
