Keypoint Visualization¶
Class: KeypointVisualizationBlockV1
Source: inference.core.workflows.core_steps.visualizations.keypoint.v1.KeypointVisualizationBlockV1
The KeypointVisualization block uses a detections from an
keypoint detection model to draw keypoints on objects using
sv.VertexAnnotator.
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/keypoint_visualization@v1to add the block as
as step in your workflow.
Properties¶
| Name | Type | Description | Refs |

name |
str |
Enter a unique identifier for this step.. | ❌ |
copy_image |
bool |
Enable this option to create a copy of the input image for visualization, preserving the original. Use this when stacking multiple visualizations.. | ✅ |
annotator_type |
str |
Type of annotator to be used for keypoint visualization.. | ❌ |
color |
str |
Color of the keypoint.. | ✅ |
text_color |
str |
Text color of the keypoint.. | ✅ |
text_scale |
float |
Scale of the text.. | ✅ |
text_thickness |
