Polygon

You can use the Polygon tool to create geometric annotations by drawing lines between points.

Import image data

To learn how to import your images directly, see Direct upload. To learn how to import your images URLs via JSON, see Import via JSON. To learn how to attach metadata to your imported images, see Asset metadata via JSON.

To learn how to import programmatically, see Bulk add data rows.

Set up Polygon

  1. Create a project.
  2. Select “Editor” as your label editor.
  3. Click “Add Object”.
  4. Select “Polygon” as your labeling tool.
  5. [OPTIONAL] Configure nested classifications.
  6. Click “Confirm”.
  7. Click “Complete setup”.

To see a sample script for setting up your project’s ontology programmatically, see Project setup script.

You also have the option to reuse ontologies from other projects. To learn more, see Ontology overview.

Create instances

From the Editor, you can create instances of your Object classes in your ontology. For example, if a labeler sees 2 birds in the image and would like to assign the "Bird" class to both, the user can create multiple instances of the "Bird" class.

To create multiple instances of the same object:

  1. Select a class and draw the object.
  2. Select the same object class again.
  3. Draw the next instance of the object.

Label format

To learn how to export your annotations, see How to export labels. To see a sample export for Polygons see Label export formats.
