Point Cloud Annotation

Overview

Appen's 3D Point Cloud Annotation tool provides the perfect balance of highly technical annotation capabilities and a simple, easy to use annotator interface that allows for fast and high-quality annotations. 

Important Note: This new tool is part of our managed service offerings. If you are interested in learning more about the Point Cloud Annotation tool, please contact your Appen Customer Success Manager or Account Executive. 

How it Works

The Point Cloud Annotation tool fuses any 3D sensor data with 2D camera images to build an intuitive annotation interface. Contributors can then create 3D annotations to bring to your models across a diverse set of industries.

Point Cloud Annotation Features 

  • Draw and Track Cuboids 
    • Annotators can draw and track cuboids on objects in sequences of point cloud data featuring sensor-fused 2D images for annotators to better visualize their annotations.
  • Ability to Validate and Improve Model Predictions 
    • If you have pre-labeled 3D annotations, you can bring these to the tool for human annotators to review. This will also help to accelerate data annotation and get precise metrics on your model’s performance.  
  • Track Occlusion and Truncation  
    • The tool allows for levels on each object for each frame for more comprehensive detection of the object.
  • Enable Faster Data Annotation with Machine Assistance  
    • The tool offers enhanced object tracking using interpolation and one-click box cuboid auto-adjustment with machine learning generated clustering. 
  • Leverage Industry-leading Interaction Design  
    • Our design allows annotators to quickly navigate the scene, understand the context and efficiently label the data. Interactive multi-angle views and sensor fusion allow annotators to choose the best view for each object.
