CA 2580875

The invention relates to image-based movement tracking of a number of objects in a particular area. A number of image registration means repeatedly records data pertaining to multiple simultaneous representations of events occurring within the area. Specifically, at least one stereo-pair of cameras (101a, 101b) repeatedly record stereo-image data (D1', D1") based upon which a data processing unit ( 110) repeatedly determines a respective position for each of the objects. According to the invention, a first camera (101a) and a second camera (101b) in the stereo-pair are separated by a base distance. Moreover, the cameras (101a, 101b) are essentially parallel and directed towards the area, such that a first image plane of the first camera (101a) registers a portion of the area, which substantially overlaps a portion of the area registered by a second image plane of the second camera (101b).

L~invention concerne un suivi de mouvement basé sur des images d~un certain nombre d~objets dans une zone particulière. Un certain nombre de moyens d~enregistrement d~images enregistrent sans cesse des données se rapportant à des représentations simultanées multiples d~évènements se produisant dans la zone. Particulièrement, au moins une paire stéréoscopique d~appareils photos (101a, 101b) enregistre sans cesse des données d~images stéréoscopiques (D1', D1") sur la base desquelles une unité de traitement de données (110) détermine sans cesse une position respective pour chacun des objets. Selon l~invention, un premier appareil photo (101a) et un second appareil photo (101b) dans la paire stéréoscopique sont séparés par une distance de base. De plus, les appareils photos (101a, 101b) sont essentiellement parallèles et dirigés vers la zone, de telle sorte qu~un premier plan d~image du premier appareil photo (101a) enregistre une partie de la zone, qui recouvre sensiblement une partie de la zone enregistrée par un second plan d~image du second appareil photo (101b).
