How to add a Rotated Bounding Box tool to your project

From the project’s Settings tab, enter the Category Schema section.

Click on Add Category. From the list that appears, click on Rotated Bounding Box.

A new row will appear named Rotated Bounding Box. Click on it to expand it.

Give your rotated bounding box tool a title.

Enable the Required toggle if you want to force labelers to create a rotated bounding box for each asset. When the toggle is disabled, labelers will be able to save and move to the next asset without creating the rotated bounding box.

If you would like to ask labelers further questions, for example, if you want to show a further radio after drawing the rotated bounding box, click on Add Classification and add a further question. More on nested questions here.

How to Draw a Rotated Bounding Box

Click on the image where you'd like the top-left corner of the rotated bounding box to be. Click again where you'd like the box to end.

You can change the angle of the box by clicking and dragging on the point located just outside the box.
