Ground and Ceiling Mover

The Ground and Ceiling Mover is a two way slider on the bottom right of the point cloud that allows users to hide points from ceiling to ground and vice-versa while labelling an object.

Ground and Ceiling sliders help filter out points which the user does not need to view.

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.

Steps to use Ground and Ceiling Slider

1. On hiding unnecessary points, users can accurately mark the points belonging to the object. For example Car parked under a Tree can be marked easily from the top view by sliding the marker from the ceiling lower, to hide points belonging to the tree top.

2. Shortcut to change Levels:

   • Ground Level (increase/ decrease) : G + Up/ Down Arrow

   • Ceiling Level (increase/ decrease) : C + Up/ Down Arrow
