scope:

This first part of ISO 20947 standard focuses on the method of quantifying the differences in body dimensions and visualizing shape differences between the human body and a virtual human body model. The standard provides performance evaluation protocol for virtual human body representation systems, which creates a virtual human body (including virtual fit mannequin) model based on 3D body scan data and/or body dimensions data of a human body. The required accuracy of a virtual human body depends on the purpose and use of the digital fitting system. Since the accuracy of scan-derived measurements and surface shape depends on the accuracy of 3D body scanner system used, manual measurements are used for quantitatively evaluating the accuracy of a virtual human body. Accuracy of scan-derived measurements should be evaluated according to ISO 20685.
