DIN ISO 18825-1:2017-04 4 IntroductionThe virtual human model exists in various formats in the virtual world and is applied in
13、 many different industrial sectors. The virtual human 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 t
14、oday, according to rapid development of the vast online 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 traditiona
15、l process of planning, production and sales. The use of 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
16、go online anytime, anywhere, to try on clothes, evaluate 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
17、 virtual human body, a necessary component of the 3D virtual 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 v
18、isual confirmation of size, shape, fit and design. This 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 digi
19、tal fitting, such as virtual human body shapes, composition 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
20、vocabulary and terminology when they devise virtual garment 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 convenie
21、nce for consumers, improve efficiency in clothing manufacturing and contribute to a decrease in the return rate of clothes purchased online.DIN ISO 18825-1:2017-04 5 Clothing Digital fittings Part 1: Vocabulary and terminology used for the virtual human body1 ScopeThis part of ISO 18825 covers vocab
22、ulary and terminology used for the virtual human body in the virtual garment system used as a main tool in various fields of clothing application. This part of ISO 18825 is applicable to all stages of online clothing communication and business, including design, manufacture, order, sales, distributi
23、on and customer management.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1 General terms2.1.1virtual human modelthree-dimensional model in digital format2.1.1.1parametric human bodyvirtual human model with changeable parameters such as size and
24、 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 differ with countries as they are based on a database. Therefore, a parametric human body can be made on the basis of height variati
25、ons, BMI (body 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.DIN ISO 188
26、25-1:2017-04 6 Figure 1 Examples of parameters of a male adult body2.1.1.2virtual human bodyvirtual human model for digital fitting in the apparel industry, including information such as size, shape, cross section, body texture and skeletal structureNote 1 to entry: Also called “fashion avatar”. In
27、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 (virtual size); see Table B.1.2.1.1.2.1virtual clonevirtual shapevirtual human
28、body that is created by forming three-dimensional surface data from a 3D body scanned point cloud (see ISO 20685:2010, 3.21), using surface modeling processes, including noise elimination, hole-filling and mesh generationNote 1 to entry: It is essential that a user get scanned first to create a virt
29、ual 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.DIN ISO 18825-1:2017-04 7 a) 3D scanning b) 3D scanned point cloud c) Virtual cloneFigure 2 Process of creating a virtual clone (virtual shape)2.1.1.2
30、.2virtual twinvirtual sizemorphed virtual human body that is applied body dimensions acquired either through manual or automatic measurementsNote 1 to entry: The virtual twin (virtual size) is a parametric human body (2.1.1.1) as it can be altered with parameters.Note 2 to entry: The virtual twin (v
31、irtual 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) Body measurements b) 3D model library c) Virtual twinNOTE Body measurements are necessary to create a virtual twin.
32、 The actual text in a) is not important.Figure 3 Process of creating a virtual twin (virtual size)2.2 Terms relating to basic composition and attributesDIN ISO 18825-1:2017-04 8 2.2.1virtual body segmentpart of the body that depicts the shape of the virtual human body (2.1.1.2)Note 1 to entry: The s
33、oftware is based on at least 10 basic virtual body segments the virtual head, virtual torso, two virtual arms, two virtual hands, two virtual legs, and two virtual feet.Note 2 to entry: A virtual body segment consists of virtual body regions. A virtual body region refers to a specific area subdividi
34、ng the virtual body segment.Note 3 to entry: The shape and size of virtual body segments can change by entering parameters of the virtual twin (virtual size) (2.1.1.2.2).2.2.2virtual cross sectionclosed contour extracted from the plane cutting a virtual body segment (2.2.1) perpendicular to its main
35、 axis or the three principle axesNote 1 to entry: See Figure 4.Note 2 to entry: The main axis is the axis that connects the joints on either side of the virtual body segment.Figure 4 Examples of virtual cross sections2.2.3virtual body dimensionsize information on virtual body segments (2.2.1) of the
36、 virtual human body (2.1.1.2) that corresponds to measured anthropometric dimensions of the user in the virtual standing positonNote 1 to entry: Virtual standing position: the head is in the Frankfurt plane, the long axes of the feet should be parallel to one another and 200 mm apart. The upper arms
37、 are abudcted to form a 20 angle with the sides of the torso and the elbows are straight. But the palms face toward the torso. This position shall be used for evaluating the fit of garments.Note 2 to entry: Virtual body dimensions for the virtual human body can be selected from anthropometric dimens
38、ions as defined by ISO 8559.EXAMPLE Virtual shoulder width, virtual crotch height, virtual neck girth, virtual waist girth, virtual hip girth, virtual knee girth, virtual calf girth, etc.2.2.4virtual body landmarkpoints which define the characteristic of the body shape of the user in the virtual sta
