A method and apparatus for deriving an occupancy map reflecting an athlete's coverage of a playing area based on real time tracking of a sporting event. The method according to the present invention includes a step of obtaining a spatio-temporal trajectory corresponding to the motion of an athlete and based on real time tracking of the athlete. The trajectory is then mapped over the geometry of the playing area to determine a playing area occupancy map indicating the frequency with which the athlete occupies certain areas of the playing area, or the time spent by the athlete in certain areas of the playing area. The occupancy map is preferably color coded to indicate different levels of occupancy in different areas of the playing area, and the color coded map is then overlaid onto an image (such as a video image) of the playing area. The apparatus according to the present invention includes a device for obtaining the trajectory of an athlete, a computational device for obtaining the occupancy map based on the obtained trajectory and the geometry of the playing area, and devices for transforming the map the a camera view, generating a color (or other visually differentiable) coded version of the occupancy map, and overlaying the color coded map on a video image of the playing area. In particular, the spatio-temporal trajectory may be obtained by an operation on a video image of the sporting event, in which motion regions in the image are identified, and feature points on the regions are tracked as they move, thereby defining feature paths. The feature paths, in turn, are associated in clusters, which clusters generally correspond to the motion of some portion of the athlete (e.g., arms, legs, etc.). The collective plurality of clusters (i.e., the trajectory) corresponds with the motion of the athlete as a whole.

A system 1000, and its alternates 1002 through 1022, for automatically tracking and videoing the movements of multiple participants and objects during an event. System 1000 and its alternates comprise a scalable area tracking matrix of overhead tracking cameras 120c, whose individual field-of-views 120v combine to form a contiguous view 504m of the performance area where the event is being held. As participants 110, and all other necessary objects such as 103 (e.g. a puck in ice-hockey) and 104 (e.g. a stick in ice-hockey) move about during the event, computer 160 analyzes the images from contiguous view 504m to create a real-time tracking database at least including participant and object centroid locations respective to the performance area, and preferably including their identities matched to these ongoing locations. System 1000 and its alternates then employ the real-time database to automatically direct, without operator intervention, one or more side-view cameras such as 140-a, 140-b, 140-c and 140-d, to maintain optimal viewing of the event. The participants and objects may additionally be marked with encoded or non-encoded, visible or non-visible markers, either denoting centroid locations visible from their upper surfaces, and / or non-centroid locations visible from perspective views. The encoded markers are preferably placed on upper surfaces and detectable by computer 160 as it analyzes the images from contiguous overhead field-of-view 504m, thus providing participant and object identities to correspond with ongoing locations, further enhancing algorithms for subsequently controlling side-view cameras 140-a through 140-d. The non-encoded markers are preferably placed on multiple non-centroid locations at least on the participants that are then adjustably viewable by system 1000 and its alternates as the system uses the determined locations of each participant from the overhead view to automatically adjust one or more side-view cameras to tightly follow the participant. The resulting images from side-view cameras 140-a through 140-d may then be subsequently processed to determine the non-encoded marker locations, thus forming a three dimensional model of each participant and objects movements.

The apparatus includes a device for obtaining the trajectory, a computational device for obtaining the performance information based on the obtained trajectory, and a statistical device for compiling the performance information. In particular, the spatio-temporal trajectory may be obtained by an operation on a video image of the sporting event, in which motion regions in the image are identified, and feature points on the regions are tracked as they move, thereby defining feature paths. The feature paths, in turn, are associated in clusters, which clusters generally correspond to the motion of some portion of the athlete (e.g., arms, legs, etc.). The collective plurality of clusters corresponds with the motion of the athlete as a whole.
