Investigating Fit in Motion with a 4D Photogrammetry Scanner System



Hohenstein Laboratories GmbH & Co. KG, Germany


Fit in motion is of vital importance for sports- and workwear. Ashdown et al. (2011) point out that valid fitting tests need to be performed in typical sports or work related movements. Only when the garment fits well in specific positions it can protect the user without restriction of the range of motion. Therefore, a comprehensive knowledge about dynamic anthropometry is needed. Bye (2006) and Bougourd (2014) believe in this as an important research field within clothing technology. In the past sizing surveys issuing the change of body dimensions due to movement could only be performed with traditional anthropometric devices. This was time consuming and therefore often uncomfortable for the participants. Through 3D scanning technology sound implementation of big analysis in dynamic anthropometry are possible. Consequently, several research projects were conducted investigating everyday, work and sport related static poses. Significant body surface and measurement changes due to movement were found.

3D scanning is not only a reliable method to capture body measurements but is utilized for garment fit investigations as well. So far, research was performed in regard of static poses. The further development from 3D to 4D changed the conditions. The interaction between garment und body in motion can be investigated with 4D scanning technology comprehensively.

In a basic research project, photogrammetry scanner "little Alice" was utilized for fit in motion assessment. "Little Alice" consists of 38 digital SLR cameras. Like every digital camera, it is possible to perform serial recording. This enables scanning in motion or 4D scanning. Three frames per second are recorded and moderate movements can be captured. In this study 25 male test subjects aged between 22-65 years (37.86 +-12) with an average body height of 181.49 cm (+-6) and chest girths 96-120 cm (German sizes 48-60) participated. They were all either athletes or physical workers. Supporting companies provided work- and sportswear clothing systems (jackets and pants). Three movements were scanned with up to seven frames. Test subjects were scanned in static poses and dynamic sequences, both in underwear and in work- or sportswear. The reference scans were performed in Vitus Smart XXL system. In addition, each scan or sequence was captured twice.

4D scanning technology can be utilized to investigate fit in motion, assessment matrices were developed, air gaps and penetration areas were identified to compare different products. 4D scans are an excellent basis for comprehensive analysis of body-garment interaction. The limitation of the study is the focus on male subjects. More studies should be performed regarding female subjects, different movements and different garments.
