3-D shape database improves fit of clothing, equipment

QUOTE
NATICK, Mass. (April 17, 2015) -- A new database at the U.S. Army Natick Soldier Research, Development and Engineering Center, or NSRDEC, is a perfect fit for America's Soldiers.
The ANSUR II 3-D Shape Database uses three-dimensional shapes and contour data to improve the fit of clothing and equipment for warfighters. It incorporates the latest Army anthropometric survey data and 3-D whole body scans, providing a searchable platform for the data and the 3-D shapes.
The center completed the latest comprehensive anthropometric survey of Soldiers, called ANSUR II, in 2012. The previous survey was completed in 1988. The 2012 survey set out to address changes in Army personnel body size and shape, and the resulting data showed that Soldiers have increased in overall body girth since 1988. The new study also set out to document the sizing needs of the increasing number of women serving in the military.
The 2012 data collection included 3-D scans of the head, foot and entire body. This innovation provided geometric and morphological data on military personnel that could not be obtained through traditional body measurement techniques.
Dr. Peng Li, a computer scientist on NSRDEC's anthropology team, is working on a novel approach to use all of the 3-D scan information to define common shapes for items, such as body armor and helmets. Scans provide contour information that is essential for proper fit.
"Peng has been working on tools to make the body scans more accessible and more usable," said Steve Paquette, a research anthropologist and team leader for NSRDEC's anthropology team.
"We developed our own shape descriptor and query method for 3-D body scans," Li said. "It will help determine different shapes for body armor and protection and gear for heads and faces."
"The anthropology team's primary mission is to maintain 'the' data base on Soldier body size," Paquette said. "This has been true since Natick opened. Most of the data over the years have been traditional measurements that you take with calipers and tape measures. With the 2012 study, we also took body scans, and it's those 3-D scans that Peng has been working with. He is actually developing tools for searching 3-D shapes.
