Workflow
Our Annotation Pipeline for This Industry
A structured, domain-specific workflow — from data ingestion to delivery.
-
01
Workspace & Object Taxonomy
Target objects cataloged with 3D reference models (CAD or scanned); workspace zones defined (pick area, place area, obstacle region, human collaboration zone). Grasp affordance categories established.
-
02
Multi-Sensor Data Alignment
RGB, depth, and LiDAR data aligned using extrinsic calibration. Point clouds registered to camera coordinate frames for consistent 3D annotation across modalities.
-
03
6-DOF Pose Annotation
Per-object 6-DOF pose (translation + rotation) annotated using 3D bounding cuboids aligned to CAD models. Grasp points labeled with approach vectors and finger placement for manipulation tasks.
-
04
Scene & Navigation Labeling
Semantic scene segmentation (floor, obstacle, shelf, conveyor) for navigation. Waypoint sequences annotated with traversability scores and clearance measurements.
-
05
Sim-to-Real Validation
Synthetic data annotations validated against real-world counterparts; domain gap metrics computed (feature distribution shift, appearance variance) to guide sim-to-real transfer learning.
-
06
Safety-Verified Delivery
Human collaboration zone annotations verified for accuracy; safety-critical labels (human presence, collision risk) receive 100% review. Delivered in ROS-compatible formats (tf, PoseStamped, PointCloud2).

Expertise
Why Domain Expertise Matters
Generic annotation vendors can label data. Domain experts label it correctly. Here's why the difference matters in your industry.
6-DOF Pose Requires Spatial Reasoning
Annotating a 6-DOF pose means understanding how a 3D object sits in space — not just drawing a box. Our annotators work with CAD model overlays and multi-view validation to achieve sub-degree rotational accuracy critical for robotic grasping.
Deformable Objects Break Standard Pipelines
A crumpled bag, a folded cloth, or a flexible package doesn't fit in a rigid bounding box. Our mesh annotation capability handles deformable objects with surface point annotations and contact region labeling for manipulation planning.
Safety-Critical HRI Demands 100% Review
When robots work alongside humans, a missed person detection can cause physical harm. All human collaboration zone annotations and human presence labels receive 100% expert review — no statistical sampling on safety-critical classes.
Comparison
UTL vs. Typical Annotation Vendor
See how our domain-specific capabilities compare to generic annotation services.
| Capability | UTL Data Engine | Typical Vendor |
|---|---|---|
| 6-DOF pose annotation with CAD alignment | ✓ Sub-degree precision | 3-DOF bounding box |
| Grasp point + approach vector annotation | ✓ Manipulation-ready | Not available |
| RGB-D + LiDAR fusion annotation | ✓ Configurable intervals | Not available |
| Sim-to-real domain gap validation | ✓ Distribution metrics | Not available |
| ROS-compatible output formats | ✓ tf, PoseStamped | Custom only |
| Deformable object handling | ✓ Mesh annotation | Rigid only |
“UTL's 3D annotation quality for our pick-and-place system was exceptional. Their team handled complex multi-object scenes with deformable packaging — a task most vendors struggle with.”

FAQs
Frequently Asked Questions — Robotics
What 6-DOF pose formats do you support?
We output pose annotations as quaternion + translation (ROS tf format), rotation matrix + translation, or Euler angles. All poses are validated against CAD model overlays with multi-view consistency checks.
Can you annotate grasp points for manipulation?
Yes. We label grasp points with approach vectors, finger placement positions, and grasp type classification (parallel jaw, suction, multi-finger). Annotations include clearance measurements and collision-free approach paths.
How do you handle sim-to-real domain gap?
We annotate both synthetic and real-world data, then compute domain gap metrics: feature distribution shift, texture/lighting variance, and object placement statistics. This data guides your sim-to-real transfer learning strategy.
Do you support ROS-compatible formats?
Yes. We deliver in ROS-native formats including tf transforms, PoseStamped messages, PointCloud2, and sensor_msgs/Image. Our pipeline also supports URDF-linked annotations for simulation integration.
