Software Improves Yuma Proving Ground Test Equipment
Researchers at the U.S. Army's Yuma Proving Ground (YPG) have developed a program that can determine the positional and angular motion of relatively stationary test objects during the various stages of their firing, using high-speed, high-definition digital camera imagery. The program gives testers detailed information in three dimensions, says YPG's John Curry and Jeff Kenney.
The software can capture physical data imagery for analysis and produce accurate results in time-space coordinates to depict an entire event. "Using a Java-based graphical user interface for cross-platform support, it provides an excellent tool for interaction with the images, allowing test engineers to see precisely how much an object moves during firing," Curry says. The software allows researchers to hand-score the first frame of a video segment and then automatically score the rest of the test, which saves time, Kenney says.
The program has already been used successfully on three different tests with more testing scheduled for future projects.
