Upload a Vision Event Image

Upload a workspace-level image and reference its sourceId when creating a Vision Event.

About

This endpoint uploads an image to your workspace for use in Vision Events. The upload is workspace-level and is not tied to any project; the returned sourceId can then be referenced in the images array when you create an event. Use it to attach the original or output frames a model processed so they are viewable alongside the event.

}

Use the sourceId value in the images[].sourceId field when creating a vision event:

  "eventType": "quality_check",
  "useCaseId": "a1b3c8e1",

    {
      "sourceId": "ve-img-abc123def456",
      "objectDetections": [
        {
          "class": "defect",
          "x": 100,

Python SDK

Upload a local image for use in vision events. The returned sourceId can be referenced in the images array when creating events.

import roboflow

roboflow.login()

rf = roboflow.Roboflow()
ws = rf.workspace()

# Upload an image
result = ws.upload_vision_event_image("inspection-photo.jpg")
source_id = result["sourceId"]

# You can also provide an optional name and metadata
result = ws.upload_vision_event_image(
    "inspection-photo.jpg",
    name="line-a-check-001",
    metadata={"camera": "cam-1", "shift": "morning"},
)

The sourceId from the response is used in the images array when creating a vision event:

ws.write_vision_event({
    "eventId": "d4e5f6a7-b2c3-4d4e-9f6a-7b8c9d0e1f2a",
    "eventType": "quality_check",
    "useCaseId": "a1b3c8e1",
    "timestamp": "2024-01-15T10:30:00Z",
    "images": [
        {
            "sourceId": source_id,
            "label": "inspection-photo",
            "objectDetections": [
                {"class": "defect", "x": 100, "y": 200, "width": 50, "height": 30, "confidence": 0.95}
            ],
        }
