Multiple object tracking system

摘要: A system (100) for tracking the movement of multiple objects within a predefined area using combination overhead X-Y filming cameras (25) and (24) with attached frequency selective filter (24f). Also employed are perspective Z Objects to be tracked have been marked reflective material, such as patches (7r 71), sticker (9) tape (4a). System radiates selected energy (23a) throughout reflect off materials. Reflected (7m, 9a 4b) is then received by while all other ambient light blocked Local Computer (60) captures images from locates said markings. Using location information along preknowledge concerning maximum rate speed size well calculated information, able extract background portion unfiltered that represent objects.
