Title
(EN) OBJECT MOTION CAPTURING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE CAPTURE DE MOUVEMENTS D'OBJET
Abstract
(EN)
In a system and method of capturing movement of an object, a tracking device is used having an optical marker and a motion sensor providing motion data representative of the position and orientation of the tracking device. The tracking device is connected to the object, and motion of the optical marker is registered by a camera to thereby provide video data representative of the position of the tracking device. The motion data and the video data are processed in combination to determine the position and orientation of the tracking device in space over time.

L'invention concerne un système et un procédé de capture de mouvement. Un dispositif de suivi y est utilisé, lequel dispositif de suivi a un marqueur optique et un capteur de mouvement délivrant des données de mouvement représentatives de la position et de l'orientation du dispositif de suivi. Le dispositif de suivi est raccordé à l'objet et le mouvement du marqueur optique est enregistré par une caméra pour délivrer, de ce fait, des données vidéo représentatives de la position du dispositif de suivi. Les données de mouvement et les données vidéo sont traitées en combinaison pour déterminer la position et l'orientation du dispositif de suivi dans l'espace et dans le temps.
