Get Started with the Ground Truth Labeler

The Ground Truth Labeler app enables you to interactively label ground truth data in a video, image sequence, or lidar point cloud. Using the app, you can simultaneously label multiple signals, such as data obtained from camera and lidar sensors mounted on a vehicle.

This example walks you through the multisignal ground truth labeling workflow in these steps.

  1. Load Ground Truth Signals to Label — Load multiple signals into the app and configure the display of those signals.

  2. Label Ground Truth for Multiple Signals — Create label definitions and label the signals by using automation algorithms.

  3. Export Ground Truth Labels for Multiple Signals — Export the labels from the app and explore the data.

You can use these exported labels, along with the associated signal frames, as training data for deep learning applications.
