Abstract:

There is much to be done to improve fitting quality of uniforms used by uniformed services in Poland. The main reasons of badly fit uniforms are inconsistency of uniform sizes in each of the services and statistical differences in body measures since the last national population survey. In order to develop the new statistics of body sizes and size charts, 3D measurements of body shape have been carried out on a large scale. Additional goal was to develop the OGX|MMS measurement system which could be used by the services in the future for periodic monitoring.
The developed system's working principle is structured light projection. The scanning system is composed of four measurement heads, each containing two 3D scanners placed vertically. Due to a spectral separation of the scanners, all measurement heads can perform data acquisition at the same time. Total measurement time is approximately 3 s. The result is a 3D cloud of points which represents the measured body surface with resolution of 1 mm and accuracy below 0.3 mm.
New algorithms were also developed for extracting anthropometric measurements from acquired body models. During the project 34 types of measurements were carried out to enable the creation of new size charts. The processing path for the measurements included filtration and measurement noise elimination, 3D segmentation, location of anatomical landmarks and calculation of body measurements (arc lengths, girths and linear sizes). A commercial Human Solutions laser line-based 3D measurement device was used as a reference for the automatically extracted measures. Comparative analysis between the two 3D scanning methods and manual measurements was performed. Manual measurements were taken according to the ISO 7501-1, ISO 8559, and EN 13402 standards. 26 features which can be used for clothing design were chosen for the analysis.
The efficiency of the scanning process was tested in a real-life environment. The main advantage of the 3D scanning method compared to the manual measurements is the ease and speed of the process and the ability to repeat measurements of the specific features using the stored virtual model.
