Common Use Cases

While simple in nature, the Line Tool is frequently used for:
  • Road Markings: Defining lanes and dividers in autonomous driving datasets.
  • Boundaries: Marking fences, walls, or architectural edges.
  • Skeletonization: Connecting keypoints to represent human or animal structures.

Flexibility

As part of the Smart Annotation Palette, the Line Tool can be used interchangeably with other tools like Bounding Boxes or Polygons within the same project. This allows for comprehensive labeling of complex scenes where different geometry types are required.
