Scope

Scope: This document specifies the terms and definitions, requirements, test and inspection methods, as well as marking, packaging, transportation, and storage for non-contact anthropometers used in clothing. It sets forth requirements and testing methods for the accuracy of measurement systems, measurement environments, test requirements for subjects, and the accuracy of measurement data. This document is applicable to the research, development, production, inspection, and use of various types of non-contact anthropometers used in clothing. Main technical content: 3. Terms and definitions The following terms and definitions apply to this document. 3.1 Non-contact anthropometer A measurement instrument that does not directly contact the human body during measurement. It uses optical and other technical means to process human body size data through software algorithms. 3.2 System calibration A process used to determine the parameters of individual three-dimensional sensors in the human measurement system and the positional relationship of all three-dimensional sensors in the world coordinate system, in order to obtain the parameters of the entire measurement system. 3.3 System scanning time The time required for a subject to stand in a specified position and adopt a standard posture from the start of scanning to the completion of all image acquisition. 3.4 System error The difference between the average value of multiple measurements of the same size under repeatability conditions and the true value of that size. 3.5 Measurement uncertainty A non-negative parameter used to quantitatively characterize the dispersion of human measurement values, reflecting the reliability and validity of the measurement results. 3.6 System measurement stability The fluctuation range of the measurement results of the human measurement instrument over time, characterized by experimental standard deviation, which indicates the ability of the measurement instrument to maintai
