Mobile phone applications for 3-dimensional scanning and digital anthropometry: a precision comparison with traditional scanners

Objective: 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.

Implications: 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.
