Training Autonomous Driving AI: Sub-Centimeter 3D LiDAR & Point Cloud Labeling
How sensor fusion, temporal 3D cuboids, and human-in-the-loop quality assurance power level 3 and level 4 autonomous vehicles across challenging edge cases.
The Challenge of Spatial Precision in 3D Point Clouds
Unlike 2D images with fixed pixel grids, LiDAR point clouds contain millions of sparse spatial coordinates. Accurately fitting 3D bounding cuboids with precise yaw, pitch, roll, and velocity vectors requires specialized tooling and rigorous human annotation.
Multi-Sensor Fusion: Camera + LiDAR + Radar
Autonomous navigation systems rely on synchronized sensor streams. Our annotation team projects 3D spatial points directly onto high-resolution 2D camera feeds to confirm object classes in rainy, nighttime, and foggy conditions.
99.8% Accuracy Benchmarks for Production ML Models
Autonomous driving safety allows zero margin for false negatives. GTS uses a three-tier QA pipeline where senior annotators audit each frame before final delivery in KITTI, COCO, or custom JSON formats.
