The BVI API suite calculates derived body composition metrics and precise linear body measurements from simple front‑and‑side photos or 3D body scans. Designed for healthcare, fitness, insurance, and retail enterprises, it automates manual measurements with fast, repeatable, privacy‑preserving analytics.

What can BVI Provide?

Using either two photos or a 3D .obj body model, we provide:

Body Volume Index (BVI) and health indicators:
- Total Body Fat %, Visceral Fat %, BVI Risk, Waist Circumference, Hip Circumference, Waist‑to‑Hip and Waist‑to‑Height ratios.
Linear Measurement Services (LMS):
- High‑precision point‑to‑point body measurements used in digital tailoring, apparel fitting, and health screening.
- Predefined “measurement packages” (e.g., uniform, leg, neck) for rapid integration into digital‑fit and health platforms.
- Capable of providing measurements between hundreds of different points, practically anywhere on the body.

This enables you to integrate ready‑made body‑analysis logic into your applications without investing in expensive clinical equipment or manually measuring people.

Benefits of BVI

Supporting weight management

Scale health & wellness programs
Improve retail & apparel digital fit
Enable research‑grade analytics
Reduce manual measurement burden
De-risk insurance policies
Privacy‑centric design

How it works with your ecosystem

Using our RESTful API, submit either:
- Front + side photos (front‑pose and side‑pose), or
- A correctly posed 3D body model (.obj)
And the persons:
- Weight
- Height
- Age
- Activity level
- Sex
The BVI API returns a structured JSON response you can plug directly into dashboards, smartphone health & fitness applications, or clinical‑support workflows.
Free integration testing allows integration without consuming paid credits, see how easy it is to integrate BVI into your products without any spend commitments. These results are randomised and for integration testing only.

What makes BVI distinct

Our approach was developed from longitudinal clinical and biomechanical research and is designed to reduce the limitations of simple BMI for health‑risk classification.

BVI’s imaging‑based, non‑invasive methodology supports large‑scale screening and remote interventions, especially where current body measurement technologies are impractical or expensive.
Linear Measurement Services provide ready‑defined, anatomically validated measurement packages that eliminate the need to reverse‑engineer biomechanical models.
BVI is patented in the US and all 28 European countries; it is the only software capable of measuring part body volume of a human in 3D.

This offering is enterprise‑ready: used by health platforms, fitness ecosystems, and digital‑retail systems to standardise body‑composition‑derived insights and streamline digital‑fit solutions on Azure.
