LiDAR Focused – Ready for Any 3D Data

Diffgram’s 3D Point cloud annotation tool is built to annotate LiDAR data faster but any type of 3D labeling is possible. The following are just some high level use-cases for “3D Annotations”. Our platform virtually supports any 3D use cases. If it does not, it must be in our roadmap.

Object Tracking

Label complex scenarios in 3D point cloud by tracking multiple frames.

Object Classification

Train computer vision models with accurate object classification for 3D Point cloud scenarios.


Segment 3D point cloud data such as cars, buildings or the sky accurately
