Cuboid

PreviousDrawing ToolsNextPolyline 3D

Last updated 1 month ago

A Cuboid is a three-dimensional annotation tool used in point cloud and image data labeling to enclose objects within a cube-like shape. By specifying the length, width, and height of the cuboid, annotators can create a box around an object, helping to define its spatial dimensions and orientation in 3D space.


Use Case

Cuboid tool is particularly useful in tasks like object detection and classification in 3D environments, such as autonomous driving, where understanding the object's size, position, and distance relative to the camera or sensor is critical. It allows accurate annotations of objects like cars, pedestrians, and buildings in real-world environments, improving the quality of training data for 3D computer vision models.

Cuboids can be created only in point cloud sensors.


Create Cuboid

  1. Select 'Cuboid' from the drawing tool list.


Modify Cuboid

The cuboid can be re-selected and modified by:

  • Select a vertex that needs to be edited and drag it to modify its location.

  • To change the yaw, pitch and roll, use CTRL (for Roll), SHIFT (for Yaw), ALT (for Pitch).

  • Drag the red, blue and green circles to modify the edge of the cuboid

  • Drag the red, blue and green lines to shift the entire cuboid in a certain direction.

  • The blue square within the cuboid allows the user to move the cuboid within one plane


Duplicate Cuboid

Cuboids can be duplicated by selecting the annotation and pressing Ctrl D. This will duplicate the cuboid and allow the user to drop it at the desired location in the point cloud on mouse-click.

Duplication of cuboid works intra-frame and does not copy the instance ID of the original Cuboid.


Copy Paste Cuboid

Copy and pasting of cuboid works inter-frame (across frames where the same instance ID doesn't exist).

Click on the '+' icon of the class from the

If the point cloud is in , the interaction to draw a cuboid will take place from the top view representing it as a Rectangle. Click and drag the mouse on the point cloud to define it from the top and then make further adjustments using from the header.

If the point cloud is in , the interaction to draw a cuboid will take place by dropping a cuboid in the point cloud and then making adjustments using from the header.

The direction the object is facing is denoted by the yellow arrow. Set the direction using the icon from the header or press shortcut R

The projection of the cuboid is simultaneously reflected in the corresponding images of the .

Enter the .

Set the cuboid dimension using quick to modify width, length and height.

The saved instance will appear on the with a box icon next to the Instance name.

Cuboids can be copy and pasted to another frame where it does not exist (Ctrl+C / Ctrl+V). The prompts user for input on pasting annotation. By default, the pasted cuboid will share the same Instance ID as the one of the copied cuboid.
