LiDAR data annotation for 3D perception, depth-accurate.

LiDAR data annotation that perception models can trust

LiDAR data annotation turns raw point clouds into the labeled 3D ground truth that autonomous driving, robotics and spatial-AI models learn from. Graveiens labels segmentation, 3D cuboids and drivable surfaces and fuses LiDAR with camera and radar so objects stay consistent across every frame and sensor. Trained annotators and SMEs work to your ontology, and a four-stage QA workflow with gold-set benchmarking keeps geometry and class labels accurate at scale. The same team supports autonomous-vehicle data annotation, image annotation and broader data annotation services, so a single vendor can cover your whole perception stack.
