ISO 20947-1 pdf download Performance evaluation protocol for digital fitting systems — Part 1: Accuracy of virtual human body representation
This document focuses on the method of quantifying the differences in body dimensions and visualizingshape differences between the human body and a virtual human body model.This document providesa performance evaluation protocol for virtual human body representation systems,which createvirtual human body (including virtual fit mannequin) models based on 3D body scan data and/or bodydimensions data of a human body. The required accuracy of a virtual human body depends on thepurpose and use of the digital fitting system.

digital fitting system
fitting system that provides qualitative and/or quantitative evaluations of overall and/or specificsimulation garment fit through analysis of the distribution of surface strain, gap between body andgarment, heat map, cross section, surface wrinkles, seam drop, garment balance, etc.
virtual human modelling system
system for creating a virtual human body (3.3.2 ) for a specific market or individualNote 1 to entry: Asymmetrical shape assumed to match the body shape of the individual.
virtual human model
three-dimensional model in digital format
[SOURCE: ISO 18825-1: 2016, 2.1.1]
parametric human body
virtual human model (3.3) with changeable parameters such as size and shape, etc.
Note 1 to entry: Parametric human body is created by modifying the parameters of the exemplar model imported from the 3D model library. The exemplar models vary by country as they are based on a database. Therefore, a parametric human body can be made on the basis of height variations, BMI (body mass index) and so on.
Note 2 to entry: The parameters of the parametric human body are presented in the parametric human body software. The parameters of the parametric human body can be added depending on the purpose of users.
Note 3 to entry: to entry See Figure 1
