    Abstract: 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).
