“…The 3D scanner system involves a light source, sensors and a controller (Wang et al 2007). Optoelectronic devices generally operate based on three different principles, including laser line scanners Chou and Hsiao 2005;Yu et al 2013), structured light scanners (Wu et al 2006) and multi-view camera systems (Jones et al 1989;Starck, Hilton, and Illingworth 2001). 3D scanners capture several images of the body surface from various angles as a 3D point cloud.…”

Anthropometry is a key element of ergonomic studies for addressing the problem of fitting the tasks/products to user characteristics, but there is a gap between anthropometric data and their application for designing ergonomic products and environments. This research was conducted to review the literature on the methodology and applications of anthropometry for the ergonomic design of products and environments, and to identify where further research is needed to improve its application and evaluation protocols. One hundred and sixteen papers meeting the inclusion criteria were reviewed. Although a number of anthropometric investigations have been conducted to improve the design of products/environments for different users, further research seems to be necessary, particularly for special groups, such as children, the elderly and people with disabilities. Different anthropometric measurement methods/techniques and fitting criteria are discussed regarding their applicability for various design applications. This review also highlights methodological issues (sampling considerations and prototype evaluation and testing) that should be considered in future research to ensure a user-centred approach of the design process. Practitioner Summary: A literature review was conducted on the methodology and applications of anthropometry for the ergonomic design of products/environments. This review emphasises the need for anthropometric research to design for special groups, such as children, the elderly and people with disabilities, and methodological issues that should be considered in future research.

“…In literature, anthropometric measurement methods can be generally divided into three categories: manual measurements [2][3][4][5], measurements using medical diagnostic devices [6][7][8][9][10][11][12][13] and measurements based on optoelectronic systems [14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…Another issue with 3D optical scanners is that they are unable to see inside the human body limiting researchers to analysis of volumetric distribution. Optoelectronic devices can operate using three different principles: laser line scanners [14,15], structured light scanners [16][17][18][19][20] and multi-image scanners [21][22][23][24]. Recently optoelectronic devices based on time-of-flight and specially constructed CMOS sensors emerged [25,26].…”

“…Several advances were introduced in the paper, including modifying light structures or coding which resulted in higher accuracy and shorter manipulation time. Wu et al [18] proposed a scanner using Gray structured light coding and with sub-pixel capabilities, resulting in depth reconstruction error of 0.254 mm (0.05% of actual depth) in simulated conditions. Recently, the Microsoft Kinect system [19] used 3D structured light technology with a static multiple dot pattern to reconstruct depth from single image, but the system has yet to be validated for anthropometric measurements.…”

“…The accuracy of measurement is related to the relationship between the projector and the cameras. Many systems [3,[5][6][7][8][9][10] assume that the optical axis of the projector lens intersects with the optical axes of the cameras' lenses and that structured light sheets are perpendicular to that plane composed of the optical axes of the cameras' lenses and the projector lens, namely, optical triangulation. In actuality, it is difficult or impossible to agree with this hypothesis as this requirement would seriously limit the implementation of the system.…”
