Hotzone

This feature is available when the user is labelling in the point cloud. It allows users to crop out an area of the point cloud to eliminate noise.

This feature is used to help focus on a specific area. The isolation is applied across the frames on the same area.

Benefits

• Enhanced Focus: Allows annotators to concentrate on a specific area of interest, eliminating distractions from irrelevant regions.

• Increased Annotation Accuracy: Provides a clearer view of smaller, detailed areas, aiding precise annotation.

• Improved Performance: Reduces computational load and improves tool responsiveness by limiting the data being processed and displayed.

Steps to use Hotzone

1

Enable Hotzone

Enable the 'Isolate' toggle from the header.

2

Define the boundary

On toggling it ON, make multiple clicks on the point cloud to draw a boundary and right click to apply hotzone.

3

Label within the isolated area

All the points falling outside the defined boundary will be hidden from view. Users can now start labelling objects in the visible patch without background disturbance.

4

Continue working across frames

• Navigate to the next frame and observe isolation is applied across frames, preserving context.

• Optionally merge the point clouds to understand the scene after removing unnecessary points.
