Tools for manual annotation

A set of tools for quality control and manual annotation of point clouds

All manual edits can be used for active training of AI models. In other word, every manual corrections that you do on the point cloud can be applied to future projects.


Point cloud annotation can be done easily with the use of intuitive tools. From each selection, a cross-section view can be generated for easier final selection.


Annotations can be done in a perspective or orthographic 3D view.

You can either annotate and assign points to classes from scratch or annotate point clouds that were automatically classified using an AI model.

A variety of tools are available:

  • Rectangle selection

  • Strip selection

  • Polygon selection

  • Clipping

Each action can be trigger using keyboard shortcuts to further reduce the time needed for annotations.
