Body scanning technologies are used in many applications, from anthropometric research to garment technology to biomechanics. While capturing a subject's body shape and measurements is often the primary objective, 3-D body scan systems can potentially add more value in some applications by determining additional body characteristics. In sports and medical science those are body mass, body surface, or overall body fat percentage.
To develop algorithms capable of calculating such values, an extensive survey was conducted in which subjects were scanned in various positions to develop a stable and practicable process that considers process-inherent perturbations. Also, additional values were collected and interviews conducted to correlate subjects' diet and activity with body characteristics.
As a result, a new method was developed that allows estimating overall body fat percentage based on 3-D scans. The new method was evaluated against widely used methodologies such as infrared interactance, skin fold measurements, and body impedance.
