What can I label in the Supervisely 3D point cloud tool?
LiDAR and RADAR point clouds, one frame at a time or as episodes, which are sequences of frames, together with the camera images of each frame. Objects get 3D cuboids, the Point Cloud Pen segments points, and boxes, polygons, brush masks and the Smart Tool work on the camera images. Tags describe an object in every frame or in one frame. See the 3D point cloud toolbox in the docs.
Which point cloud formats can I import and export?
Auto Import reads PCD, PLY, LAS and LAZ files natively, and annotated datasets in KITTI 3D, KITTI-360, SemanticKITTI, nuScenes, Lyft, ROS bag and Supervisely format. Export apps write Supervisely JSON, KITTI 3D, nuScenes, SemanticKITTI and ROS bags. See the supported point cloud formats.
How does sensor fusion annotation work in Supervisely?
Every frame carries its camera images with their calibration. The toolbox projects each 3D object onto the images, links a label drawn on an image to the same object in 3D, and turns a 2D box or mask into a 3D object with Create 3D Objects from 2D Objects on Camera. The Camera Device color mode also paints the points with the colors of the photos.
Does the 3D AI assistant need training on my data?
No. The assistant is class-agnostic: it fits cuboids, detects objects and segments the ground for any object without fine-tuning, and its cuboid tracking aligns neighboring scans with point cloud registration instead of a trained model. You can also serve your own 3D detectors, such as MMDetection3D models. See AI for 3D point clouds in the docs.
How large can a point cloud be?
The toolbox renders with WebGPU in the browser. In the docs benchmarks, 40 million points run at about 52 fps on a MacBook Air M4 and 100 million points at 115+ fps on a MacBook Pro (M4 Pro), and one scene holds up to 1,000 annotated objects. See performance for dense clouds.
Can I label point clouds for free?
Yes. The free Community plan includes the 3D toolbox with interactive photo context for up to 50 point cloud files. The 3D AI assistant, with cuboid adjustment, the 3D Smart Tool, ground segmentation and cuboid tracking, comes with the Cloud Max add-on for Pro (+€399) or with Enterprise, where tracking can also run your own models.
