Abrégé
(EN)

A system100for tracking the movement of multiple objects within a predefined area using a combination of overhead X-Y filming cameras25and tracking cameras24with attached frequency selective filter24f. Also employed are perspective Z filming cameras25and tracking24cameras with filter24f. Objects to be tracked have been marked to include some form of frequency selective reflective material, such as an ink. Marked objects such as patches7rand7l, sticker9and tape4ahave been specified and are attachable to said multiple objects. System100radiates selected energy23athroughout the predefined area of tracking that is specifically chosen to reflect off said reflective materials used to mark said objects. Reflected energy such as7m, 9aand4bis then received by tracking cameras24while all other ambient light is blocked by filter24f. Local Computer System60continuously captures images from said tracking cameras24which include only the minimum information created by said reflected energy. System60efficiently locates said markings on said multiple objects and uses this location information to analyze synchronously captured unfiltered images from filming cameras25. Using said location information along with pre-knowledge concerning said multiple objects maximum rate of speed and maximum size as well as calculated information such as the vectors of direction, acceleration and velocity based upon previous movements, system60is able to efficiently find and extract the background the portion of the unfiltered images that represents said multiple objects.
