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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 20685 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 3,
Anthropometry and biomechanics.
This second edition cancels and replaces the first edition (ISO 20685:2005), of which it constitutes a minor

ISO 20685:2010(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
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 International Standard 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 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 ISO 20685 is to ensure comparability of body measurements as specified by 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 by conformance with this International Standard any
data extracted from scans will be suitable for inclusion in international databases such as those described in
ISO 15535.
INTERNATIONAL STANDARD ISO 20685:2010(E)

3-D scanning methodologies for internationally compatible
anthropometric databases
1 Scope
This International Standard addresses protocols for the use of 3-D surface-scanning systems in the
acquisition of human body shape data and measurements defined in ISO 7250-1 that can be extracted from 3-
D scans. It does not apply to instruments that measure the location and/or motion of individual landmarks.
While mainly concerned with whole-body scanners, it is also applicable to body-segment scanners (head
scanners, hand scanners, foot scanners).
The intended audience is those who use 3-D scanners to create 1-D anthropometric databases and the users
of 1-D anthropometric data from 3-D scanners. Although not necessarily aimed at the designers and
manufacturers of those systems, scanner designers and manufacturers will find it useful in meeting the needs
of clients who build and use 1-D anthropometric databases.

The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE In the case of definitions of terms for skeletal landmarks, when there is a separate term for the skin overlying
the landmark and another for the landmark itself, the skin landmark term is used. Where there is no separate term, the
skeletal term is used and assumed to refer to the skin overlying the landmark.

NOTE Many anthropometric distances can be calculated from the coordinates of anatomical landmarks. Some
additional points may be necessary to obtain circumferences.
