人体工程学 国际兼容的人体测量数据库的 3D 扫描方法 第 2 部分：表面形状和相对地标位置可重复性的评估协议

[中文适用范围]： 本文件建立了测试 3-D 表面扫描系统获取人体形状数据和测量值的协议。它不适用于测量单个标志运动的仪器。虽然本文件主要涉及全身扫描仪，但也适用于身体部分扫描仪（头部扫描仪、手部扫描仪、足部扫描仪）。它适用于以单一视图测量人体的身体扫描仪。当评估手持式扫描仪时，人类操作员可能会对整体误差产生影响。当评估参与者旋转的系统时，可能会引入运动伪影；这些也会导致整体误差。本文件适用于由体格测量师确定的标志位置。它不适用于软件从点云自动计算的标志位置。人体表面形状和标志位置的质量受扫描仪系统和人类（包括测量员和参与者）的性能影响。本文件通过使用伪影而不是人类参与者作为测试对象来解决扫描仪系统的性能问题。传统仪器需要精确到毫米。可以通过将仪器与根据国际长度标准校准的刻度进行比较来验证其准确性。为了验证或指定人体扫描仪的准确性，使用已知形状和尺寸的校准测试对象。目标受众是使用 3-D 人体扫描仪创建 3-D 人体测量数据库的人、这些数据的用户以及人体扫描仪设计者和制造商。本文件旨在为扫描仪用户和扫描仪提供商以及 3-D 人体测量数据库提供商和数据用户之间就人体扫描仪的性能达成一致提供基础。 [外文原描述]： This document establishes 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, this document is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). It applies to body scanners that measure the human body in a single view. When a hand-held scanner is evaluated, the human operator can contribute to the overall error. When systems are evaluated in which the participant is rotated, movement artefacts can be introduced; these can also contribute to the overall error. This document 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 the performance of scanner systems and humans, including measurers and participants. This document addresses the performance of scanner systems by using artefacts rather than human participants as test objects. Traditional instruments are required to be accurate to the 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, the users of these data, and body scanner designers and manufacturers. This document intends to provide the basis for 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.
