Find Data Labelers for LiDAR and 3D Point Cloud Annotation

You can hire for 3D cuboid and bounding box annotation, semantic segmentation, instance segmentation, multi-frame object tracking, sensor fusion annotation combining LiDAR and camera data, quality assurance and validation, and more. Whether you need single-frame labeling or complex multi-sequence tracking with consistent object IDs, you can find experienced Data Labelers in our network.

Our network includes Data Labelers with experience across autonomous vehicles, robotics, drones and UAVs, construction, urban planning, industrial inspection, AR/VR, and more. Most specialize in one or two verticals, so you can find annotators who understand your domain and data.

It depends on your project. You can hire annotators for high-volume cuboid labeling, specialists for complex segmentation or tracking work, or QA leads to review annotations and resolve edge cases. Many teams hire a mix based on task complexity and quality requirements.

Data Labelers work directly in your stack. This includes commercial 3D annotation platforms, open-source tools like CVAT, point cloud viewers, or your own internal tooling. OpenTrain is tool-agnostic, so you invite hires to your environment and maintain full control over access and data.

Pricing is set between you and the Data Labelers you hire. Rates vary based on annotation type, complexity, and required experience. You can review proposals, compare rates, and negotiate directly. Payments are handled through OpenTrain with funds released upon your approval.

Direct hire gives you full control. You post a job, review proposals, hire Data Labelers, and manage the work yourself using OpenTrain's built-in tools. Managed service is for larger or ongoing projects where you want OpenTrain to handle recruiting, quality management, and delivery end-to-end.
