3D Bounding Boxes

Overview: Bounding box annotation is used to train autonomous vehicles to detect various objects in a real-world scenario. The objects are detected in the point cloud with high accuracy by using bounding boxes.
Steps to create a 3D bounding box:
  1. 1.
    Click on Label type and select 3D bounding box from the top left menu of the editor.
  2. 2.
    To Create a Bounding Box: Start labelling by clicking on Create Tool(C) using Left-click on the left-hand sidebar. Note that it only adds bounding boxes in this mode.
  3. 3.
