Quantitative Comparison of Manual vs. 3D Scanner Human Body Measurements
Bremen University, Bremen, Germany
Human body measurements are actively used in the clothing industry for production or finding the best possible garment fit. For the last few years digital methods based on 3D scans are replacing the traditional manual measurement techniques. In this paper we determine the quality of measurements obtained with a 3D scanner in terms of reliability and validity. Tape measurements from two expert measurers were used as a reference. Reliability comparison was evaluated in terms of Standard Error of Measurement and difference from mean distribution. Validity was analyzed according to ISO 20685.
Data used for the analysis were gathered during Phase 2 of "Comparative Analysis of measurement methods of 3D body scanning" organized by IEEE Industry Connections 3D Body Processing group hosted in Instituto de Biomecanica de Valencia (IBV).
For all 3D scanner measurements 90% of differences from mean are inside the ANSUR (Anthropometric Survey of US Army Personnel) allowable error interval. It was also shown that reliability of measurements obtained with Texel Portal MX 3D scanner is nearly twice better than reliability of manual measurements. Upon application of constant offsets these two measurement techniques are compatible according to ISO 20685.
