3D Imaging Technology for Human Body Size and Shape Analysis: Comparison of Three Different Acquisition Technologies

Anthropometric measurements of body size and shape are widely used in diagnosing, monitoring, and assessing the risk of developing adiposity-related chronic metabolic diseases. Recent technological advances have extended anthropometry beyond traditional tape-derived measurements to automated 3D digital image acquisition devices that can rapidly acquire hundreds of linear, circumferential, and volumetric body dimensions. The aim of the current study was to compare measures across three imaging devices differing in acquisition and data processing technology (16 stationary Microsoft Kinect Cameras (MKC)[KX16, TC2]; and single vertical movable optical light-coding camera [Proscanner, Fit3D Inc.] or stationary MKC V2 camera [Styku, Inc.] with 3600 rotating platforms) and against traditional reference methods including total body volume (TBV) by air displacement plethysmography (ADP), circumferences by tape anthropometry, and regional body volume by dual-energy x-ray absorptiometry (DXA).
