Labeling
Use the Lidar Labeler app to interactively label ground truth data in a point cloud or a point cloud sequence. You can label cuboids and polylines for object detection, voxels for semantic segmentation, and scenes for point cloud classification. To learn how to label a point cloud sequence, see Get Started with the Lidar Labeler.
The app provides algorithms to automate the labeling process for object tracking and interpolation. You can use one of the included algorithms, or create and import a custom automation algorithm. For more information, see Create Automation Algorithm for Labeling.
You can also use Lidar Toolbox™ functions to define labels and programmatically automate the labeling process.
