3D Data
Point Cloud Annotation
Turning 3D Sensor Data Into AI Intelligence
LiDAR sensors generate highly detailed 3D representations of the physical world. But raw point clouds are difficult for machine learning systems to interpret without structured labels.
LiDAR annotation adds meaning to this data by identifying objects, surfaces, movement, and spatial relationships. These labeled datasets help AI systems understand their surroundings and make better predictions.
Complete 3D Point Cloud Annotation
Our annotation workflows can be adapted to different LiDAR sensors, environments, object classes, and machine learning requirements.
3D Bounding Boxes
Precisely identify and label vehicles, pedestrians, cyclists, buildings, machinery, and other objects within 3D point clouds.
Point Cloud Segmentation
Classify individual points or regions to help AI systems understand roads, vehicles, vegetation, buildings, infrastructure, and environments.
Cuboid Annotation
Create accurate 3D cuboids around objects while capturing their position, dimensions, orientation, and spatial relationships.
Semantic Segmentation
Assign meaningful classes to point cloud data for scene understanding, autonomous navigation, robotics, and mapping.
Sensor Fusion
Combine LiDAR with camera and other sensor data to create richer multimodal datasets for advanced AI systems.
3D Object Tracking
Track objects across sequential LiDAR frames to support perception, motion prediction, and autonomous navigation models.
