Opc.Ua.Vision

Server/client-independent foundation for the draft OPC UA — Vision companion specification.

The Vision NodeSet is source-generated here directly over the base OPC UA namespace (no DI, Machinery or Robotics dependency), exposing generated ObjectTypes, ReferenceTypes, enums, typed node states and client proxies, plus the AddOpcUaVision model loader. The generated ObjectTypeIds, ReferenceTypeIds and DataTypeIds classes are the source of truth for the model.

The model covers the vision domain end-to-end: a VisionRootType topology grouping vision sensors (VisionSensorType, ImageSensorType, Depth3DSensorType) together with their OpticsType and IlluminationType components; CoordinateFrameType, VisionCalibrationType, IntrinsicCalibrationType and ExtrinsicCalibrationType for the spatial grounding of every sensor; media surfaces (MediaEndpointType, StreamEndpointType, ClipEndpointType, VisionMediaManagementType) for how image and video data leaves the server; inference (InferencePipelineType); results (VisionResultType, InspectionResultType, DetectionResultType, SegmentationResultType) and their VisionFeedbackType correction cycle; and the IVisionSimulatedType marker interface for simulated sensors. The HasCalibration, MountedOn, HasScenePrim and ProducedBy reference types carry the semantic relationships between these components.

Numerical conventions

Every DataType in this package respects §5.12 of the specification:

  • Positions are metres.
  • Orientations are unit quaternions ordered (x, y, z, w).
  • VisionIntrinsicsDataType.Cx / Cy are corner-datum principal-point coordinates.
  • An empty covariance array is the sentinel for "not reported" — not a zero matrix.
Package Adds
OPCFoundation.NetStandard.Opc.Ua.Vision.Server Hosting a Vision server: AddVision, ConfigureVision, provider abstractions, fluent topology builders, facet derivation
OPCFoundation.NetStandard.Opc.Ua.Vision.Client VisionClient discovery, sensors, media, inference, results, VisionFrameGraph pose composition, VisionFeedbackClient

OPCFoundation.NetStandard.Opc.Ua.Mcp.Vision MCP tools for perception agents, including vision_get_frame returning an MCP ImageContentBlock

See the Vision developer guide for the full end-to-end story, code examples and the bin-picking sample.

The namespace http://opcfoundation.org/UA/Vision/ and every NodeId in it are provisional. The model is a working-group draft.

Package Downloads
OPCFoundation.NetStandard.Opc.Ua.Vision.Client

Client-side helpers for the OPC UA Vision (draft) companion model: discover the well-known Vision root, browse sensors, calibrations and coordinate frames, compose transforms across the frame tree, drive inference pipelines, read detection, inspection and segmentation results, and submit feedback (detections, corrections, image references) to a Vision server.
OPCFoundation.NetStandard.Opc.Ua.Vision.Server

Server hosting for the draft OPC UA Vision companion model. Publishes the well-known Vision root under the Server object, wires host-supplied providers for media (streams, clips), inference and feedback, exposes a fluent build API, and derives conformance facets from the materialised address space.
