Digital Anthropometric Video-Imaging Device (DAVID) Versus Anthropometer Measurements

摘要

Anthropometric data are essential in the development and design of items in industry, transportation, and housing. Anthropometry is particularly important in military aviation due to restrictive environments found in cockpits and the limited range of motion allowed for safe operation of controls. Methods of obtaining anthropometric measurements are varied; they range from manual techniques, such as tape measures and calipers to three- dimensional whole-body scanners. In addition to these methods, a computer-based technique called the digital anthropometric video-imaging device (DAVID) has been developed at the Naval Aerospace Medical Research Laboratory, in Pensacola, Florida. The DAVID provides a means to capture and measure a person's digital image using off-the-shelf hardware and software. A study comparing 6 anthropometric measurements (sitting height, sitting eye height, sitting acromial height, thigh clearance, buttock/knee length, and sitting knee height) was completed on 236 aviation candidates (200 males and 36 females) using both the DAVID and manual (anthropometer) measurement methods. The mean data measurements compared favorably with data reported in previous anthropometric surveys. The results of this study indicate the DAVID technology provides comparative results to standard manual methods for the measurements tested.
