Keypoint Annotation Services

Human pose keypoint and skeletal tracking annotation for sports analytics, fitness AI, and robotics perception models.

Keypoint Annotation Services
  • Skeletal and pose keypoints
  • Multi-person scene handling
  • Sports and fitness taxonomies
  • Temporal keypoint tracking

Service overview

Pose estimation, ergonomics scoring, and sports performance products rely on accurate skeletal keypoints — not approximate joint placements. Our keypoint annotation services label human pose, hand articulation, and custom skeleton schemas for video and still imagery at production scale.

Why keypoint precision matters

Small joint errors compound into wrong angle calculations and false injury-risk scores. We train annotators on sport-specific and occupational pose taxonomies with consensus review on occluded and fast-motion frames.

Keypoint labeling scope

Full-body COCO-style poses; sport-specific joint sets; hand and face landmarks; animal pose for veterinary AI; ergonomic joint angles for workplace safety scoring on video feeds.

Video keypoint tracking

Maintain joint identity and temporal smoothness across frames for broadcast sports, fitness apps, and physical therapy movement analysis — with frame sampling QA on high-velocity sequences.

Industry applications

Football and basketball analytics, yoga and fitness form correction, factory ergonomics monitoring, clinical gait analysis support datasets, and robotics human-interaction perception.

QA for pose datasets

Geometric consistency checks, blind review on difficult poses, and IAA measurement on ambiguous occlusion cases before release to your training jobs.

Get started

Build pose datasets that movement models can trust. Share joint schema, sport or use-case context, and frame volumes — we scope keypoint annotation capacity and QA depth.

Industries we serve

Our annotation process

A proven calibration-to-production workflow for enterprise annotation programs.

01

Share Your Data

Upload raw images, video, text, audio, or LiDAR securely — we ingest from cloud storage, SFTP, or your existing ML pipeline.

02

Project Analysis

We define labeling guidelines, class taxonomy, edge cases, and accuracy targets with your ML and product stakeholders.

03

Annotation

Trained annotators label bounding boxes, masks, tracks, transcripts, or 3D cuboids in your toolchain or our workspace.

04

Quality Assurance

Multi-pass review, consensus scoring, and automated checks before any dataset reaches your training jobs.

05

Delivery & Support

Receive COCO, JSON, Pascal VOC, or custom exports — plus ongoing support as your models and taxonomies evolve.
