Différence entre nuScenes and nuScenes-lidarseg:

• In March 2019, we released the full nuScenes dataset with all 1,000 scenes.
• In July 2020, we released nuScenes-lidarseg. In nuScenes-lidarseg, we annotate each lidar point from a keyframe in nuScenes with one of 32 possible semantic labels (i.e. lidar semantic segmentation). As a result, nuScenes-lidarseg contains 1.4 billion annotated points across 40,000 pointclouds and 1000 scenes (850 scenes for training and validation, and 150 scenes for testing).

To facilitate common computer vision tasks, such as object detection and tracking, we annotate 23 object classes with accurate 3D bounding boxes at 2Hz over the entire dataset.
