3D Scanning
The article evaluates the precision of digital anthropometry through 3-dimensional (3D) scanning. Historical methods using large, expensive, non-portable systems has been well established. This study explores the comparative performance of modern mobile applications.
A mobile 3D scanning app that uses full rotation of subjects around a smartphone camera showed similar reliability to larger, more expensive 3D scanners. However, a mobile app using just two 2D images had larger errors, though still acceptable for certain uses.
Key takeaway
Independent research from Texas Tech University confirms that Size Stream’s mobile scanning technology delivers precision comparable to traditional booth-sized scanners, with body fat estimates showing error margins of just 0.4–0.9% across all systems tested. Notably, Size Stream’s SS20 booth scanner demonstrated virtually identical performance metrics across a four-year span, underscoring the platform’s exceptional consistency and maturity. Together, these findings validate 3D body scanning as a reliable tool across an expanding range of health, fitness, and clinical applications, accessible whether in a professional setting or via a smartphone.
