Complex anthropometrics such as area and volume, can identify changes in body size and shape that are not detectable with traditional anthropometrics of lengths, breadths, skinfolds and girths. However, taking these complex with manual techniques (tape measurement and water displacement) is often unsuitable. Three-dimensional (3D) surface imaging systems are quick and accurate alternatives to manual techniques but their use is restricted by cost, complexity and limited access. We have developed a novel low-cost, accessible and portable 3D surface imaging system based on consumer depth cameras. The aim of this study was to determine the validity and repeatability of the system in the measurement of thigh volume. The thigh volumes of 36 participants were measured with the depth camera system and a high precision commercially available 3D surface imaging system (3dMD). The depth camera system used within this study is highly repeatable (technical error of measurement (TEM) of <1.0% intra-calibration and ~2.0% inter-calibration) but systematically overestimates (~6%) thigh volume when compared to the 3dMD system. This suggests poor agreement yet a close relationship, which once corrected can yield a usable thigh volume measurement. 相似文献

The paper crosses the boundaries between different genres, drawing on key material and emphasising the philosophical challenges around decision-making and values in relation to replication and replicas. In 1968, Philip K. Dick wrote the book Do Androids Dream of Electric Sheep? which became the inspiration for the 1982 film Bladerunner. The book is set in Los Angeles in a post-apocalyptic future where mankind has left Earth, resulting in androids being created to develop new ‘off-world’ colonies. The book and film create a novel and interesting framework to discuss the subject of replicas and replication within contemporary conservation practice. Key themes are decay promoting replication, original versus replica, creating empathy in replication. The debate focuses on the case study of Naum Gabo's Construction in Space (Crystal) of 1937–39; which was the sculpture replicated in the most recent replication project at Tate, completed in July 2015. 相似文献
