Opc.Ua.Vision.Client

Client-side helpers for the OPC UA — Vision companion model (working-group draft).

Built on Opc.Ua.Vision and Opc.Ua.Client, this package exposes a high-level surface over the source-generated proxies so a client can drive a Vision server without knowing NodeIds or BrowseNames:

  • VisionClient — resolves the well-known Vision object (§4.2) and enumerates sensors, inference pipelines, and coordinate frames;
  • VisionSensorClient — reads a sensor's identity, imaging members, optics, illumination, mounted frame and calibrations (intrinsic and hand-eye extrinsic);
  • VisionFrameGraph — walks the CoordinateFrameType tree and composes transforms between any two named frames (camera → flange → base, camera → flange → tool centre point). Follows the §5.12 conventions exactly — right-handed frames, quaternion order (x, y, z, w), corner-datum principal point, and refuses a non-unit quaternion within tolerance 1e-6;
  • VisionMediaClient — GetClip by reference (default), inline LatestClip/LatestClipMetadata, and honest surfacing of the §6.4 case where inline delivery is disabled (Bad_NotSupported);
  • VisionPipelineClient — RunInference, StartContinuous, Stop, and reading pipeline members including the deployment inference location;
  • VisionResultReader — reads DetectionResultType, InspectionResultType, SegmentationResultType and streams result changes over an IStreamingSubscription;
  • VisionFeedbackClient — SubmitDetections, SubmitInspectionResult, SubmitCorrection, SubmitImageReference, the headline path for an off-server vision-language model publishing results the Server did not compute;
  • AddVisionClient() — DI registration for IOpcUaClientBuilder;
  • session.Vision(telemetry) — non-DI extension for creating a client over any connected ISession.

Example

using Opc.Ua.Client;
using Opc.Ua.Vision;
using Opc.Ua.Vision.Client;

// From any connected session:
VisionClient vision = session.Vision(telemetry);
if (!vision.IsVisionNamespaceAvailable)
{
    return; // Server does not implement Vision.
}

await foreach (VisionNodeEntry sensor in vision.EnumerateSensorsAsync(ct))
{
    VisionSensorClient s = vision.Sensor(sensor.NodeId);
    VisionSensorIdentity identity = await s.ReadIdentityAsync(ct);
    // Read intrinsic / hand-eye calibrations, media endpoints, etc.
}

// Read the latest detection result for a pipeline, then compose the
// first detection's pose from the camera frame into the world frame.
VisionFrameGraph frames = vision.Frames();
VisionDetectionResultSnapshot det =
    await vision.Result(resultNodeId).ReadDetectionAsync(ct);
if (det.Detections.Count > 0 && det.Detections[0].HasPose)
{
    VisionPose3DDataType inWorld = await frames.ComposeAsync(
        det.Detections[0].Pose, cameraFrameNodeId, worldFrameNodeId, ct);
}

See the Vision developer guide for discovery, streaming, feedback and the frame-graph composition example.

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