Abstract:

This paper presents partial results of a larger validation study of two innovative products based on Data-driven 3D Reconstruction (D3DR) technology: a smartphone app, Avatar3D, and a portable booth, DomeScan. This study quantifies the reliability (Standard Error of Measurement, SEM, Intra-class Correlation Coefficient, ICC) of the automatic foot measurements elicited by these solutions and compares it to traditional anthropometry and to a commercial laser foot scanner. Moreover, it assesses the compatibility (systematic bias) of measurements among these techniques. The results show that, for the six measurements assessed, D3DR is as reliable as high resolution 3D scanners and more reliable than manual measurements made by an expert. Due to its lower cost, speed and portability they could be more suitable for retail and home environments than actual 3D scanners.
