Landmark Annotation & Keypoint Annotation Services

High-volume landmark annotation — 10+ years’ experience, 540+ annotators, 38M+ images; ISO, HIPAA & GDPR-aligned for enterprise teams

Landmark annotation and keypoint labeling services explaining how precise coordinates improve spatial accuracy across diverse AI applications.

Landmark annotation supplies exact coordinates for key points and reference markers in images and video. These labels support object localization, spatial alignment, and 3D reconstruction—capabilities used in autonomous navigation, facial and hand analysis, AR, sports analytics, and imaging. Quality landmarks reduce model errors, strengthen spatial understanding, and speed deployment.

Precise BPO India combines 10+ years of experience with 540+ annotators to deliver scalable landmark datasets. Our workflows fit SBU, MBU, and enterprise needs: we define taxonomies, point structures, and labeling rules so each coordinate matches client and model requirements.

We have processed 810M+ images, including 38M+ landmark tasks across automotive, healthcare, retail, agriculture, geospatial, sports, robotics, and industrial AI. This scale helps clients train large models, manage lifecycles, and iterate consistently across versions. Security and quality are core.

We implement ISO 27001 controls and follow GDPR- and HIPAA-aligned practices where needed. Multi-stage QC—automated checks, reviewer audits, and sampling—maintains accuracy for high-volume datasets and specialized workflows.

Serving the US, UK, EU, ME, APAC, LATAM and global markets, Precise BPO India provides India-based, cost-efficient landmark annotation that improves spatial accuracy and accelerates production AI. From face and hand landmarking for gesture and expression analysis to sports action landmarks, AR point mapping, and 3D reference markers, we deliver consistent, model-ready datasets.
