Lidar Labeling

Interactive ground truth labeling in lidar point clouds

Use the Lidar Labeler app to interactively label ground truth data in a lidar point cloud or point cloud sequence. You can define cuboid regions of interests (ROIs) and use them to interactively label ground truth data. Use labeled lidar point clouds to train deep learning models. To automate the labeling process, you can use a built-in automation algorithm or develop your own algorithm. The app also provides APIs for categorizing labels and for creating label definitions. To start labeling an object, see Get Started with the Lidar Labeler.
