Abstract: A system is described for interactively analyzing plays of a sporting event based on real-world positional tracking data. Using positional information regarding the players and/or ball and/or other objects obtained from a tracking system, along with identified event data and contextual information, the system processes a library of plays (e.g., one or more seasons' worth of a league's contests) into a searchable database of plays using multiple alignment templates and discriminative clustering techniques. A user interface is described for interacting with the database in a graphical manner, whereby users can query a graphical depiction of a play and receive the most similar plays from the library, along with statistical information relating to the plays. The user interface further permits the user to modify the query graphically (e.g., moving or exchanging players, ball trajectories, etc.) and obtain updated statistical information for comparison.

Abstract: A system is described for analyzing plays of a sporting event based on body-pose information in conjunction with real-world positional tracking data. The system permits segmentation of sporting event plays into discrete time periods and the labeling of appropriate body-pose characteristics for each period. The system allows for comparison and fine-grained analysis of plays with respect to either a series of body-pose vertices that exist in continuous space (i.e., skeleton) or map directly to attributes, using the positional tracking data and play information to account for contextual differences. To enable analysis for the former, the system performs a projection to 3D space, followed by a spatiotemporal alignment step. Through the system, the importance of particular body-pose motions or specific attributes to the success of particular sporting event plays is quantified.

Abstract: It is provided a method for conveying data on a flying object in a scene. The method including capturing video frames of the scene by video cameras to get video frames which include image of the object, identifying the object in captured video frames to get associated object parameters, calculating motion variables, solving motion equations for anticipated object trajectory taking into account certain effects, and conveying data to displaying devices. The certain effects are an effect of object collision with a ground surface, air friction, wind effect, and interaction of a spinning object with air. The method may be applied to a ball in a sporting playing field. The cameras may have variable operating parameters desirable for the calculating the motion variables, which may be determined by camera calibration using captured artifacts of the scene. Shadow of the object may be captured as well and be used to provide data absent due to occluding a of the object from a video camera.

Abstract: It is provided a system for embedment within a sport playing object, a ball for example. The system is associated with continuous determination of a state of the object, its location and pose. The system includes an inertial navigation system (INS) module first state module adapted for measuring parameters associated with the object state, a wireless transmitter, a battery for providing electric power, and a mounting module connecting the object with the first state module, the wireless transmitter and the battery. Independent data relating to the object state is provided by a second state module, a camera system for example. The object state is calculated in accordance with the parameters measured by the first state module and in accordance with the independent provided data. The camera system capturing the object includes at least two mutually displaced camera clusters, and each camera cluster includes one or more cameras for providing a predetermined spatial resolution.

Abstract: An application for a method of tracking and assessing rentals includes entering renter information regarding a renter and entering rental assessment data regarding at least one rental at a client computer and transferring the renter information and the rental assessment data from the client computer to a server computer system. In the server computer system, an overall assessment is created from the rental assessment data and the renter information, the rental assessment data and the overall assessment is stored in a database record associated with the renter.
