An instrument with relatively new application to anthropometry is a three-dimensional (3-D) scanner. 3-D
34、 scanners generate a 3-D point cloud of the outside of the human body that can be used in a number of situations including clothing and automotive design, engineering and medical applications. Recently, digital human models are created from a 3-D point cloud, and used for various applications relate
35、d to technological design process. Quality control of scan-extracted anthropometric data is important since required quality can differ according to applications.There are a number of different fundamental technologies that underlie commercially available systems. These include stereophotogrammetry,
36、 ultrasound and light (laser light, white light and infrared), among others. Further, the software that is available to process data from the scan varies in its methods. Additionally, methods to extract landmark positions are different between commercially available systems. In some systems, anthrop
37、ometrists decide landmark locations and paste marker stickers, and scanner system calculate locations of marker stickers and identify their names, while in other systems, landmark positions are automatically calculated from the surface shape data. Quality of landmark locations have significant effec
38、ts on the quality of scan-extracted 1-D measurements as well as digital human models created based on these landmarks.As a result of differences in fundamental technology, hardware and software, the quality of body surface shape and landmark locations from several different systems can be different
39、for the same individual. Since 3-D scanning can be used to gather these data, it was important to develop an International Standard that allows users of such systems as well as users of scan-extracted measurements to judge whether the 3-D system is adequate for these needs.The intent of this part of
40、 ISO 20685 is to ensure the quality control process of body scanners, especially that of surface shape and locations of landmarks as specified by ISO 7250-1.DIN EN ISO 20685-2:2017-05 EN ISO 20685-2:2017 (E)5 1 ScopeThis part of ISO 20685 addresses protocols for testing of 3-D surface-scanning syste
41、ms in the acquisition of human body shape data and measurements. It does not apply to instruments that measure the motion of individual landmarks.While mainly concerned with whole-body scanners, it is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). This Intern
42、ational 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 artefacts can be introdu
43、ced; these can also contribute to the overall error. This 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 of surface shape of the human body and landmar
44、k positions is influenced by performance of scanner systems and humans including measurers and subjects. This part of ISO 20685 addresses the performance of scanner systems by using artefacts rather than human subjects as test objects.Traditional instruments are required to be accurate to millimetre
45、. Their accuracy can be verified by comparing the instrument with a scale calibrated according to an international standard of length. To verify or specify the accuracy of body scanners, a calibrated test object with known form and size is used.The intended audience is those who use 3-D body scanner
46、s to create 3-D anthropometric databases including 3-D landmark locations, the users of these data, and scanner designers and manufacturers. This part of ISO 20685 intends to provide the basis for the agreement on the performance of body scanners between scanner users and scanner providers as well a
47、s between 3-D anthropometric database providers and data users.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
