3D Point Cloud Annotation is visualizing labelled objects in 3D point clouds. Labelling objects at every single point with great accuracy makes 3D point cloud annotation capable to detect objects up to 1 cm with 3D boxes with definite class annotation for right dimensions and tracking label. It can classify each object having the additional attribute that a model can detect for machine learning. Uniworld Outsourcing’ 3D point cloud annotation services can help to differentiate lanes types to annotate the roads for safe driving of autonomous vehicles and to identify objects in indoor and outdoor of space.
