ISO 20685-2-2015 pdf free.Ergonomics一3-D scanning methodologies for internationally compatible anthropometric data bases一 Part 2: Eva luation protocol of surface shape and repeatability of relative landmark positions. This part of ISO 20685 addresses protocols for testing of 3-D surface-scanning systems in the acquisition of human hotly shape data and measurements. It does not apply to instruments that measure the illotion of individual landmarks. While mainly concerned with whole-body scanners, it is also applicable to body-segnwnt scanners (head scanners, hand scanners, toot scanners). This International Standard applies to body scanners that measure the human body in a single view. When a hand-held scanner is evaluated, it has to be noted that the human operator can contribute to the overall error. When systems are evaluated in which the subject is rotated, movement artelacts can he introduced; these can also contribute to the overall error. ‘rhis 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. The quality ol’ surface shape of the human body and landmark positions is influenced by performance of scanner systems and humans including measu rers and subjects. This part of ISO…
