3D Annotation FAQs

Common questions about our point cloud annotation services

We support PCD, LAS, LAZ, PLY, XYZ, and custom binary formats. We also work with sensor-specific formats from Velodyne, Ouster, and other LiDAR manufacturers.

We achieve sub-meter accuracy with 99.8% precision. Our annotators use specialized 3D annotation tools and undergo rigorous training for spatial labeling tasks.

Yes, we specialize in multi-frame annotation with object ID persistence across sequences for tracking and motion prediction applications.

Typical turnaround is 48-72 hours for standard 3D cuboid annotation. Complex segmentation tasks take 3-7 days depending on point density and scene complexity.

Yes, we can annotate synchronized LiDAR and camera data, providing consistent labels across both modalities for sensor fusion applications.
