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

用于利用带有固定的频率选择滤波器(24f)的头顶X-Y取景摄象机(25)和跟踪摄象机(24)的组合跟踪在预定区域内多个目标的运动的系统(100)。同样采用的是带滤波器(24f)的透视Z取景摄象机(25)和跟踪摄象机(24)。要被跟踪的目标已经被标记有频率选定的反射材料,如补丁(7r和7l)、标记物(9)和条带(4a)。系统(100)遍及跟踪区域辐射选定的能量(23a)以被所述反射材料反射。被反射的能量如(7m、9a和4b)然后被跟踪摄象机(24)接收,同时所有的其他周围光线被滤波器(24f)阻挡。本地计算机系统(60)捕捉来自跟踪摄象机(24)的图像并定位所述标记。利用预关于多目标最大速率和最大尺寸以及被计算的运动信息一起的所述位置信息,系统(60)能够分离代表所述多目标的非滤波图像(25)的背景。
