Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

ISO 20685-1:2018(E)
Introduction
Anthropometric measures are key to many International Standards. These measures can be gathered
using a variety of instruments. An instrument with relatively new application to anthropometry is a
three-dimensional (3-D) scanner. 3-D scanners generate a 3-D point cloud of the outside of the human
body that can be used for a number of purposes, such as clothing and automotive design, engineering
and medical applications. There are currently no standardized methods for using 3-D point clouds in the
design process. As a result, many users extract one-dimensional (1-D) data from 3-D point clouds. This
document concerns the application of 3-D scanners to the collection of one-dimensional anthropometric
data for use in design.
There are a number of different fundamental technologies that underlie commercially available
systems. These include stereophotogrammetry, ultrasound and light (laser light, white light and
infrared). Further, the software that is available to process data from the scan varies in its methods.
Additionally, software to extract dimensions similar to traditional dimensions varies markedly in
features and capabilities.
As a result of differences in fundamental technology, hardware and software, extracted measurements
[1]
from several different systems can be markedly different for the same individual. Since 3-D scanning
can be used to gather measurements, such as lengths and circumferences, it was important to develop
an International Standard that allows users of such systems to judge whether the 3-D system is
adequate for these needs.
The intent of this document is to ensure comparability of body measurements as specified in ISO 7250-1
but measured with the aid of 3-D body scanners rather than with traditional anthropometric
instruments such as tape measures and callipers. It is further intended that conformance with this
document will make any data extracted from scans suitable for inclusion in international databases
[2]
such as those described in ISO 15535.
