Abstract
In spite of highly standardised protocols designed to maximise the degree of repeatability and accuracy, anthropometric data are not always as reliable as they appear. Many factors come into play during the measurement of human subjects, resulting in numerous possible sources of error. Researchers have found the magnitude of these errors to be such that, even if measured by highly trained observers, comparison of two populations may be meaningless. Computerised image-based systems can overcome some of the problems of traditional anthropometry, such as error due to the pressure exerted on soft tissue by measurement instruments, or transcription errors. However, all sources errors are not eliminated by computerised measurement. In image-based systems, the sources of error take the form of perspective distortion, camera resolution, and inadequacy of the mathematical models used to estimate circumference measurements. The accuracy of measurements made by an image-based clothing and equipment sizing system was estimated using a database of 349 subjects (male and female) who were also measured traditionally. The precision, or repeatability, of this system was estimated through repeated measurements of both a plastic mannequin and a human. TRUNCATED
