Apparatus to track one or more than one athlete performing in an athletic event within an area for hosting the event, the apparatus comprising a. a laser ranging system (LIDAR system) a camera, and a data processing system; i. the LIDAR system and the camera bearing respective fields of view (108,110), the fields of view are arranged to overlap to survey a common volume of the sports environment, ii. the LIDAR system is arranged to produce LIDAR data relating to a respective set of one or more than one athlete of said one or more than one athlete performing in the athletic event within the sports environment, iii. the data processing system being arranged to process the LIDAR range data to distinguish between foreground points and background range data; the foreground points being associated with at least said respective set of one or more than one athlete of said one or more than one athlete performing in the athletic event within the sports environment; and iv. the camera is arranged to produce camera video image data relating to a respective set of one or more than one athlete of said one or more than one athlete performing in the athletic event within the sports environment objects, and the apparatus being characterised by: b. a correlator i. for identifying, or correlating, said foreground points and camera video image data associated with a common athlete in both sets of said one or more than one athlete of said one or more than one athlete performing in the athletic event within the sports environment, within the field of views of both the LIDAR system and the camera; ii. for determining the identity of the common athlete from said the camera video image data associated with the common athlete; and iii. for producing athlete attribute data associated with the identity of the common athlete; the athlete attribute data comprising at least one or more than one of position, speed, direction or velocity data. a. a laser ranging system (LIDAR system) a camera, and a data processing system; i. the LIDAR system and the camera bearing respective fields of view (108,110), the fields of view are arranged to overlap to survey a common volume of the sports environment, ii. the LIDAR system is arranged to produce LIDAR data relating to a respective set of one or more than one athlete of said one or more than one athlete performing in the athletic event within the sports environment, iii. the data processing system being arranged to process the LIDAR range data to distinguish between foreground points and background range data;
