3D Annotation and Labeling Services
Unidata delivers high-precision 3D annotation for AI training—from LiDAR and meshes to medical scans. We label bounding boxes, segment objects, and track motion across autonomous driving, robotics, healthcare, and construction. Our expert team ensures quality, scalability, and fast turnaround.
- 95%+ annotation accuracy
- 1,000+ domain-matched annotators
- Pilot launched within days
Data Annotation Vs Labeling Tasks
| 3D Data Annotation | 3D Data Labeling | |
|---|---|---|
| Definition | Detailed marking of three-dimensional objects, surfaces, volumes, and spatial relationships within 3D models or scenes | Assigning classification labels to entire 3D objects or simple volumetric regions |
| Work Coverage | Comprehensive spatial understanding: object boundaries in 3D space, surface normals, volumetric occupancy, scene composition | Object-level or simple region categorization without detailed geometric boundaries |
| Common Tasks | • 3D bounding cuboids • Mesh segmentation • Point cloud classification per point • Surface normal annotation • Volumetric occupancy marking • 3D keypoint detection • Scene graph generation • Object pose estimation | • 3D object classification (chair/table/car) • Scene type identification • Simple presence/absence of objects • Basic material type tagging • Indoor vs. outdoor categorization |
| Complexity Level | Very high complexity: requires 3D spatial reasoning, understanding of geometry, and multi-view perspective integration | Medium complexity: requires basic 3D understanding but without precise boundary marking |
| ML Impact | Enables: 3D object detection, scene understanding, robotics manipulation, AR/VR applications, 3D reconstruction | Enables: 3D object classification, basic scene categorization, 3D search and retrieval |

How Unidata Provide Data Labelling Process
A Clear, Controlled Workflow From Brief to Delivery
- You
- Share your raw data, annotation requirements, and quality standards
- Unidata
- We analyze your data, define the methodology, and assign a dedicated project lead. The right annotation type and domain-matched annotators are confirmed before anything starts.
- You
- Review annotated samples, validate quality, and approve scope before full-scale work begins.
- Unidata
- We annotate a small representative sample and deliver a clear cost estimate broken down by complexity, hours, and validation rounds.
- You
- Review and sign. Scope, quality thresholds, and deadlines are all defined in writing upfront.
- Unidata
- We prepare a full confidentiality agreement covering your data, guidelines, and any proprietary model details.
- You
- Share existing guidelines and format requirements. No guidelines yet? We build them together.
- Unidata
- We configure the right annotation platform for your data type: Labelbox, SuperAnnotate, CVAT, or Label Studio. Workflows, label taxonomy, and quality benchmarks are set before a single label is applied.
- You
- Review sample batches at each milestone and share feedback with your project lead.
- Unidata
- Trained, domain-matched annotators work through your dataset. No batch moves forward without passing internal quality checks.
- You
- Review edge cases and confirm acceptance criteria before final delivery.
- Unidata
- Every batch goes through automated validation and human review. Inter-annotator agreement (IAA) is tracked throughout. Inconsistencies are caught and resolved before the dataset moves forward.
- You
- Receive your annotated dataset in the format you need: COCO, Pascal VOC, JSON, CoNLL, PCD, or custom. Full quality report included.
- Unidata
- Clean, validated, training-ready data delivered on schedule. Final invoice aligned to the scope agreed at Step 02.

Data Annotation Challenges? Value You Get with Unidata
Real Challenges
- No annotators, tools, or workflow to process collected data
- No quality check on labeled data before it hits the pipeline
- No way to ensure two annotators label the same object consistently
- Can’t find annotators with LiDAR, medical, or financial expertise
- Scope creep and rework cycles exhaust the budget before delivery
Value with Unidata
- Project lead assigned and pilot launched within days
- Every batch validated before delivery, 95%+ accuracy via multi-stage QA
- Label consistency tracked per batch, issues caught before training fails
- 1,000+ annotators matched by domain — the right expert, every time
- Pilot-first pricing, fixed scope, zero hidden rework charges
Data Annotation Files Example
Working with annotation data from CVAT and JSON formats, you'll receive optimized code that seamlessly processes both file types, complete with practical examples and visual representations of your data structure.
