Ground Truth Labeler
Label ground truth data for automated driving applications
Description
TheGround Truth Labelerapp enables you to label ground truth data in multiple videos, image sequences, or lidar point clouds.
Using the app, you can:
Simultaneously label multiple time-overlapped signals representing the same scene.
Define rectangular region of interest (ROI) labels, polyline ROI labels, pixel ROI labels, cuboid ROI labels for lidar labeling, and scene label definitions. Use these labels to interactively label your ground truth data.
Use theProjected Viewoption to view the labels in top, front and side views simultaneously.
Use built-in detection or tracking algorithms to label ground truth data.
Write, import, and use custom automation algorithms to automatically label ground truth data.
Evaluate the performance of your label automation algorithms by using a visual summary.

Tips
To avoid having to relabel ground truth with new labels, organize the labeling scheme you want to use before marking your ground truth.
You can copy and paste labels between signals that are of the same type.
