DIN EN ISO 20685-2:2024-03

This document establishes protocols for testing of 3-D surface-scanning systems in the acquisition of human body shape data and measurements. It does not apply to instruments that measure the motion of individual landmarks. While mainly concerned with whole-body scanners, this document is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). This International Standard applies to body scanners that measure the human body in a single view. When a hand-held scanner is evaluated, the human operator can contribute to the overall error. When systems are evaluated in which the participant is rotated, movement artefacts can be introduced; these can also contribute to the overall error. This part of ISO 20685 applies to the landmark positions determined by an anthropometrist. It does not apply to landmark positions automatically calculated by software from the point cloud. This part of ISO 20685 addresses the performance of scanner systems by using artefacts rather than human participants as test objects. The intended audience is those who use 3-D body scanners to create 3-D anthropometric databases, the users of these data, and body scanner designers and manufacturers. This part of ISO 20685 intends to provide the basis for agreement on the performance of body scanners between scanner users and scanner providers as well as between 3-D anthropometric database providers and data users. This document (EN ISO 20685-2:2022) has been prepared by Technical Committee ISO/TC 159 "Ergonomics" in collaboration with Technical Committee CEN/TC 122 "Ergonomics", the secretariat of which is held by DIN (Germany). The responsible German standardization committee is Working Committee NA 023-00-03 GA "Gemeinschaftsarbeitsausschuss NAErg/NAM: Anthropometrie und Biomechanik" ("Joint Working Committee NAErg/NAM: Anthropometry and biomechanics") at DIN Standards Committee Ergonomics (NAErg).
