3D body scanning is an application[1] of various technologies such as Structured-light 3D scanner, 3D depth sensing, stereoscopic vision and others for ergonomic and anthropometric investigation of the human form as a point-cloud. The technology and practice within research has found 3D body scanning measurement extraction methodologies to be comparable to traditional anthropometric measurement techniques.[2][3]

Applications[]

While the technology is still developing[when?] in its application, the technology has regularly been applied[4] in the areas of:

  • Adapted performance sportswear
  • Fashion design (e.g. garments, accessories)
  • 3D printed figurines (3D selfies)
  • 3D morphometric evaluation (i.e. for weight-loss purposes[5])
  • Ergonomic body measurement
  • Body shape classification[6]
  • Comparison of changes in body positions [7]

However, despite the potential for the technology to have an impact in made-to-measure and mass customisation of items with ergonomic properties, 3D body scanning has yet to reach an early adopter or early majority stage of innovation diffusion. This in part due to the lack of ergonomic theory relating to how to identify key landmarks on the body morphology.[8][9] The suitability of 3D Body scanning is also context dependent as the measurements taken[10] and the precision of the machine [11] are highly relative to the task in hand rather than being an absolute. Additionally, a key limitation of 3D body scanning has been the upfront cost of the equipment and the required skills by which to collect data and apply it to scientific and technical fields.

Scanning protocol[]

Although the process has been established for a considerable amount of time with international conferences held annually for industry and academics (e.g. the International Conference and Exhibition on 3D Body Scanning Technologies), the protocol and process of how to scan individuals is yet to be universally formalised.[12] However, earlier research [13] has proposed a standardised protocol of body scanning based on research and practice that demonstrates how non-standardised protocol and posture significantly influences body measurements;[14] including the hip.[15]

The standard scanning protocol, however, produces no measurements that fail to meet the precision of manual measurement methods or ISO 20685:2010's[16] tolerances. But through consecutive scanning and a free algorithm called GRYPHON,[17] 97.5% of measurements meet ISO 20685:2010; a precision increase of 327%.[18]
