How it works

Video in. 3D motion data out.

No special equipment, no calibration, no bottleneck. Our neural network handles landmark detection, temporal smoothing, and 3D reconstruction — from any footage you already have.

Step 01 — Footage

Any video, any camera

Any saved MP4, MOV, or AVI — phone, camera, or existing video. No minimum resolution, no controlled environment required. Video is processed and immediately deleted.

Step 02 — Reconstruct

AI extracts the skeleton

Deep neural networks detect 500+ anatomical landmarks per frame, reconstruct 3D joint positions, and apply temporal smoothing to eliminate jitter — no physical markers required.

Step 03 — Output

Keypoints and skeleton data

Receive 2D and 3D keypoints, skeleton tracking, and joint-angle data — structured for analysis, visualisation, and downstream integration into animation and biomechanics workflows.

Who it's built for

One pipeline. Three high-value verticals.

The same markerless engine powers game studios, sports scientists, and clinicians — each with a fundamentally different use case and ROI.

Sports & Biomechanics

Quantify movement from footage you already have

Turn years of training and competition footage into joint-angle data, gait metrics, and kinematic sequences — no retroactive marker placement needed.

  • Joint-angle time series for any lower or upper body segment
  • Gait cycle detection — stance, swing, cadence, symmetry
  • Joint-angle and gait data structured for analysis

Clinical & Research

Objective movement data without a lab visit

Clinical gait labs run $200–$500 per assessment. SnapMeasureAI extracts comparable kinematic outputs from a smartphone clip — enabling remote monitoring and large-scale research cohorts.

  • Remote gait and balance assessment from patient video
  • Longitudinal tracking — repeat assessment from any camera
  • No biometric identifiers retained after processing

FAQs

Common questions

How is this different from Vicon, OptiTrack, or Xsens?+

Traditional optical systems (Vicon, OptiTrack) require a calibrated multi-camera volume, retro-reflective markers, and trained operators — hardware costs start at $10,000+, with studio day rates of $1,500–$5,000. Inertial systems (Xsens, Rokoko) still require a sensor suit. SnapMeasureAI requires nothing from the subject — just standard video from any camera. The trade-off is lab-grade sub-millimetre precision versus practical, scalable accuracy from footage you already have.

What was the model trained on, and how accurate is it?+

The model was trained on over 13 million images and video frames across a wide range of body types, poses, and environments. It performs well on everyday movement — walking, exercise, sport, and on-set performance. Get in touch if you'd like to discuss a specific use case.

What video quality is needed?+

The technology is designed to work with standard video — no special camera or settings required. Higher quality generally helps, but we've seen good results from low-quality footage too.

What data does the technology output?+

The technology produces 2D and 3D keypoints, skeleton tracking data, and joint-angle time series. Export to formats like FBX and BVH, and direct integration with Unreal, Unity, Blender, and Maya, are available for enterprise engagements — contact us to discuss your pipeline requirements.

How is video data handled after processing?+

Video files are deleted immediately after the skeleton output is generated. No footage is stored, no biometric data is retained, and no personally identifiable information is kept.

How do I explore a pilot or integration?+

Email info@snapmeasureai.com with a brief description of your use case. We'll follow up to discuss your footage, output requirements, and how the technology fits your workflow.
