MachineVision
Machine Vision — industrial cameras, image-processing systems, vision-guided inspection. Two enums, 14 typed structures covering recipes, results, calibration. No upstream dependency.
OPC UA companion specification for machine-vision systems — industrial cameras, image-processing engines, vision-guided inspection. Standardised by the VDMA.

None — MachineVision is a root spec.
Notable types
The 14 DTOs cover the vision-system lifecycle:
- Recipe / configuration — recipe definitions, calibration records, parameter sets
- Run / result — typed inspection results, defect records, image references
- Metadata — environment data, lighting configuration
For a typical inspection-result read, expect a strongly-typed DTO that aggregates pass/fail status, measurement values, and optional image references.
Notable enums
RecipeAuthorisationEnum— recipe-access controlCalibrationStateEnum— calibration validity
