Hardware Set-Up Recommendations for an Outdoor Motion Capture System with an Application in Overground Running

Abstract

Gait analysis laboratories are a successful and useful resource in the medical field, but oftentimes, progressed rehabilitation and testing requirements outgrow the restrictions of an indoor laboratory. Naval Medical Center San Diegos (NMCSD) mobile motion capture system is used to collect overground running data on part of an outdoor 400m track. The set-up consists of 12 Raptor-E motion capture cameras (Motion Analysis Corp., Santa Rosa, CA) collecting 3D positional kinematic data at 300Hz and four portable force plates (Kistler Instrument Corp., Amherst, NY) collecting kinetic data at 1800Hz. Placing the motion capture cameras on tall tripods and aiming them down at the capture volume proves successful at minimizing extraneous reflections caused by sunlight reflecting off surrounding objects. Aluminum plates are positioned underneath all force plates and spacers to decrease unwanted movement that is a result of being placed on a polyurethane track.
