Industrial drawing analysis large model
SCENE · Machining/Technology · Drawings and BOM
Use "Layout - Semantics - Geometry - Consistency - Manual Confirmation" to string together non-standard image files; output structured fields instead of black box summaries to support downstreamMES / PLMdocking.
Five-step pipeline
- Layout analysis: Picture frame, title bar, details bar partition; handle scanning distortion and multi-page PDF.
- information extraction: Table and annotation text structuring; units and tolerance regularization.
- symbol recognition: Geometric tolerances, roughness, welding symbols, etc. are analyzed according to national/enterprise standard templates.
- Pattern analysis: View relationship, sectioning and local magnification index; key dimension chain extraction.
- Manual verification: About 10% of the random inspection interfaces focus on low-confidence fields to avoid heavy work for all employees.
Core indicators (project actual measurement interval)
| Review preparation hours | Compared with the original process, the maximum80%Decrease (industry related to image file complexity) |
| Dimensions and parameter extraction | In a stable production line scenario, the accuracy rate can reach95%+ |
| Traceability | Field → Element Bounding Box → Original document page number link remains intact |
The above picture comes from the existing delivered materials and is used to represent the interaction form of "extraction results + artificial focus".
Format and interface
Input side compatible with PDF,DWG, DXF, high-resolution raster images, andSTEP, PRTand other 3D CAD formats; the output side supports JSON, tables and configurableCSV, and expose the difference comparisonAPIfor change management.
Deployment and hardware
| project | suggestion |
|---|---|
| reasoning | GPUVideo memory ≥ 16 GB (single task concurrent benchmark) |
| storage | Versioned image file warehouse supports audit mode of only adding but not changing |
| network | Intranet offline inference is optional; update packages can be delivered via the bastion host |
