The virtual human

17、body used in the fashion field reflects the attributes of different areas of the human body based on physical measurements and shape characteristics.Various types of virtual human body-based IT-fashion convergence technology are being attempted today, according to rapid development of the vast onlin

18、e fashion market, including the internet, mobile market, smart TVs, and virtual fittings at shops and stores. Meanwhile, the increased demand of mass customized and made-to-measure garments these days encourages efforts to innovate the traditional process of planning, production and sales. The use o

19、f digital technology in this new ubiquitous environment of the international apparel industry is leading to use of three-dimensional information on consumers and digital human bodies that reflect somatotype characteristics, and consumers can now go online anytime, anywhere, to try on clothes, evalua

20、te the style and fit, and place orders. Despite such advances, there is a lack of an International Standard related to the virtual human body.Therefore, this part of ISO 18825 is the first in a series of International Standards that deal with the virtual human body, a necessary component of the 3D v

21、irtual garment system used in the apparel industry. The main goals of this International Standard are to define a virtual human body to be used to improve online communication and reliability of fashion products sold online and in-store through visual confirmation of size, shape, fit and design. Thi

22、s International Standard will establish a single index and reference for all virtual garment programs that are currenlty using various, confusing terminology.This part of ISO 18825 specifies vocabulary, terminology and definitions related to digital fitting, such as virtual human body shapes, compos

23、ition and attributes, and thus supports online and in-store consumers, fashion designers, product developers, technologists, manufacturers and retailers who have an interest in the style and fit of clothes. Developers will be able to use unified vocabulary and terminology when they devise virtual ga

24、rment systems. Online consumers, fashion designers, manufacturers and sellers using virtual garment systems will be able to make use of the vocabulary and terminology regarding virtual body dimensions. It is therefore expected to improve convenience for consumers, improve efficiency in clothing manu

25、facturing and contribute to a decrease in the return rate of clothes purchased online.

28、.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 differ with countries as they are based on a database. Therefore, a parametric human body can be made on the basis of height variations, BMI (b

29、ody mass index) and so on (see Figure A.1).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: See Figure 1.INTERNATIONAL STANDARD

In computing, an avatar is the graphical representation of the user or the users alter ego or character.Note 2 to entry: The virtual human body is classified into two key types virtual clone (virtual shape) and virtual twin (virt

33、1 to entry: It is essential that a user get scanned first to create a virtual clone (virtual shape).Note 2 to entry: The virtual clone (virtual shape) is identical to the body shape of the user.Note 3 to entry: See Figure 2.2 ISO 2016 All rights reservedBS ISO 18825-1:2016ISO 18825-1:2016(E)a) 3D sc

35、size) is a parametric human body (2.1.1.1) as it can be altered with parameters.Note 2 to entry: The virtual twin (virtual size) is not identical to the user; but is a close approximation that can be altered by entering parameters retrieved from a population database.Note 3 to entry: See Figure 3.a)
