Abstract
(EN)
A three-dimensional motion detection apparatus and detection method using a stereo camera are disclosed. The three-dimensional motion detection apparatus, according to the present invention, can calculate information on the motion of a pointer using a method for calculating the actual location, moving direction, moving distance, and speed of the pointer corresponding to a specific part of a human body to be tracked by using the stereo camera. Furthermore, the present invention can detect only the motion of a specific user in front of the camera by setting a reference location for motion detection and limits the detection range on the basis of the set reference location.

La présente invention concerne un dispositif de détection tridimensionnelle de mouvement et un procédé de détection utilisant une caméra stéréoscopique. Le dispositif de détection tridimensionnelle de mouvement selon la présente invention peut calculer des informations sur le mouvement d'un pointeur au moyen d'un procédé de calcul de l'emplacement réel, du sens de mouvement, de la distance de mouvement, et de la vitesse du pointeur correspondant à une partie précise d'un corps humain destinée à être suivie au moyen de la caméra stéréoscopique. En outre, la présente invention est capable de détecter uniquement le mouvement d'un utilisateur précis situé devant la caméra en définissant un emplacement de référence pour la détection de mouvement, et limite la plage de détection en fonction de l'emplacement de référence défini.
