"Automatic system for tracking the movement of multiple objects within a predefined area.For the supply by remote system selective information on displacement of multiple objects within a predefined area and for tracking of movements, including direction and guidanceMultiple objects within a predefined area and process to extract efficiently an object from its background image ".A system (100) for tracking multiple objects in displacement of a predefined area using a combination of X - y suspended filming cameras (25) and tracking cameras(24) with filter (24F) frequ00b3u00eancia selectively incorporated. Are also employed cameras filming Z in Perspective (25) as well as tracking cameras (24) with filter (24F).Objects to be tracked, such as badges (7R and 71), adhesive label (9) and tape (4a) were marked with a material reflexu00edvel of frequ00b3u00eancia selective.The system (100) radiates selected energy (23a) through the area of tracking to reflect these materials form.The energy reflected that type (7m, 9a and b) is then received by tracking cameras (24) while all other ambient light is blocked by the filter (24F).The system of the local computer (60) captures images from the cameras and tracking (24) and locates the said signals.Using said location information with prior knowledge regarding the maximum speeds and the maximum sizes of said multiple objects.As well as information of displacement is calculated, the system (60) can extract the background of unfiltered images (25) that represent the said multiple objects.
