Tracking of articulated pose and motion with a markerized grid suit

Abstract

Despite leaps in motion capture technology, the dichotomy between unencumbered vision-based motion recovery and the prevailing marker-assisted motion capture solution remains largely pertinent. This paper bridges the gap by introducing an attachment-free, full-body motion capture technique that employs multiple high-speed cameras and a customized bodysuit. The flexible bodysuit allows free movements while providing marker data for guided reconstruction of pose and motion. Our method overcomes several practical problems in existing systems, including long preparation time and displaced markers. The network of markerized pattern provides connectivity information and enhances robustness in feature tracking, model matching and 3D reconstruction. © 2008 IEEE.
