BS ISO 20685-2:2015阐述了采集过程中三维表面扫描系统的测试协议 人体形状数据和测量数据。它不适用于测量运动的仪器 各个地标。虽然主要涉及全身扫描仪，但它也适用于身体部分扫描仪 （头部扫描仪、手部扫描仪、脚部扫描仪）。本国际标准适用于人体扫描仪 从一个角度来测量人体。当评估手持式扫描仪时，必须注意 人工操作可能导致整体错误。 当评估系统时 旋转主体，可以引入运动人工制品；这些也会导致整体错误。 ISO 20685的本部分适用于人体测量师确定的地标位置。事实并非如此 应用于由软件从点云自动计算的地标位置。人体表面形状和标志性位置的质量受性能的影响 扫描仪系统和人类，包括测量人员和受试者。ISO 20685的这一部分涉及 通过使用人工制品而不是人类受试者作为测试对象来测试扫描仪系统的性能。 传统仪器需要精确到毫米。其准确性可通过以下方式验证: 将仪器与根据国际长度标准校准的天平进行比较。到 验证或指定身体扫描仪的准确性，使用已知形状和尺寸的校准测试对象。目标受众是那些使用三维人体扫描仪创建三维人体测量数据库的人 包括三维地标位置、这些数据的用户，以及扫描仪设计师和制造商。 ISO 20685的本部分旨在为车身性能协议提供依据 扫描仪用户和扫描仪供应商之间以及三维人体测量之间的扫描仪 数据库提供者和数据用户。交叉引用:ISO 7250-1ISO 10360-8ISO 20685VDI/VDE 2634-2:2002购买时可用的所有当前修订版均包含在本文件的购买中。

BS ISO 20685-2:2015 addresses protocols for testing of 3-D surface-scanning systems 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 International 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 introduced; 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 landmark 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. 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 scanners 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 as between 3-D anthropometric database providers and data users.Cross References:ISO 7250-1ISO 10360-8ISO 20685VDI/VDE 2634-2:2002All current amendments available at time of purchase are included with the purchase of this document.
