CROSS-REFERENCE TO RELATED APPLICATION(S)
This application is related to U.S. patent application Ser. No. 13/471,404 entitled “SYSTEM AND METHOD FOR AUTOMATIC VIDEO FILMING AND BROADCASTING OF SPORTS EVENTS” filed May 14, 2012 and incorporated by reference in its entirety; U.S. patent application Ser. No. 13/660,385 entitled “SPORTS APPARATUS AND METHOD” filed Oct. 25, 2012 and incorporated by reference in its entirety; and U.S. patent application Ser.

FIELD
The present disclosure generally relates to sports monitoring systems, and more specifically, to sports monitoring systems for determining one or more periods of time when one or more projectiles are likely to be spatially closely associated with one or more players. Further, the present disclosure relates to methods of operating the sports monitoring systems. Furthermore, the present disclosure also relates to software products recorded on machine-readable data storage media, wherein the software products are executable upon computing hardware to implement aforesaid methods.
BACKGROUND
In various team sports, it is often desirable to know when one or more players have been in contact with a projectile. For example, in a game of American football, it would be desirable to keep a track of which player has been carrying the projectile (i.e., a football) during playing of the game. Presently, such tracking is often implemented by using cameras, and personnel collating statistics manually.
However, these conventional techniques suffer from a number of disadvantages. Firstly, a viewer watching the game may not be able to identify which player has been carrying the projectile, for example, because of an unclear camera view. Secondly, manual tasks are bound to involve risks of human errors.
U.S. Pat. No. 8,353,791 discloses a method of tracking possession of a sports projectile such as a ball. Based on disclosure a ball has short range radio beacon and each player has receiver for the radio beacon signals and GPS. System can be used to determine which player is in possession of the ball. Problem with said solution is that ball possession could be determined to be on any player in proximity of the ball.
Therefore, there exists a need for a system for determining one or more periods of time when one or more projectiles are likely to be spatially closely associated with one or more players, in an automatic manner.

Beneficially, at least one of the data processing arrangement and the sensor units may utilize a portable computing device for their implementation within the sports monitoring system.
Referring now to the drawings, particularly by their reference numbers, FIG. 1 is a schematic illustration of an example playing scenario in which a sports monitoring system is implemented pursuant to the present disclosure. For the sake of simplicity, FIG. 1 shows a portion of a playing area, where one or more players, depicted as a player 102a, a player 102b and a player 102c, are playing a game. The player 102a, the player 102b and the player 102c are hereinafter collectively referred to as players 102.
The sports monitoring system includes one or more projectiles, depicted as a projectile 104 in FIG. 1. The projectile 104 is useable in the game to be played by the players 102.
The projectile 104 is provided therein with an associated motion sensing arrangement and a data recording arrangement (not shown in FIG. 1). The motion sensing arrangement of the projectile 104 is operable to generate one or more motion-indicative signals corresponding to the projectile 104. The data recording arrangement of the projectile 104 is then operable to record the motion-indicative signals as a function of time.
The motion sensing arrangement of the projectile 104 may be operable to provide data indicative of acceleration and/or rotation and/or orientation of the projectile 104 as a function of time, wherefrom the aforementioned motion-indicative signals corresponding to the projectile 104 may be generated. For this purpose, the motion sensing arrangement of the projectile 104 may include at least one of following sensors: accelerometer, magnetometer, pressure sensor, temperature sensor, gyroscopic sensor, microphone, GPS sensor or other indoor/outdoor location sensor, and timer.
The motion-indicative signals corresponding to the projectile 104 may include information about at least one of: an identification code (ID) associated with the projectile 104, one or more movements (for example, accelerations and/or rotations and/or orientations) of the projectile 104, one or more spatial positions of the projectile 104, sound received by microphone, and associated time stamps. In addition to time stamps the received (and recorded) audio can be used for time stamping purposes. In addition recorded sound can be used to determine if a projectile is in motion i.e. used as motion-indicative signal.
The sports monitoring system also includes one or more sensor units for the players 102 to carry, for example, by wearing the sensor units during playing of the game. With reference to FIG. 1, the player 102a is wearing a sensor unit 106a, the player 102b is wearing a sensor unit 106b, and the player 102c is wearing a sensor unit 106c. The sensor unit 106a, the sensor unit 106b and the sensor unit 106c are hereinafter referred to as the sensor units 106. The players 102 may, for example, wear the sensor units 106 by a detachable attachment to waist, wrist, ankle, or any other suitable part of body or in the sporting equipment carried by the players 102. In some embodiments the sensor unit 106 is attached to player 102 in a way that it is possible to determine orientation of the player 102 in respect to playing field. In some embodiments player 102 might have more than one sensor 106.
For example, the sports monitoring system may be implemented for use in a game of ice hockey, wherein the playing area may be an ice hockey rink, and the projectile 104 may be a hockey puck. Accordingly, the player 102a may be carrying and/or wearing one or more sports equipments, such as a hockey stick, hockey skates, a hockey helmet, protective gloves and various protective pads, during playing of the game. Beneficially, the sensor unit 106a may be implemented spatially within at least one of the sports equipments carried and/or worn by the player 102a. 
Each of the sensor units 106 is provided therein with an associated motion sensing arrangement and a data recording arrangement (not shown in FIG. 1). The motion sensing arrangement of the sensor unit 106a is operable to generate one or more motion-indicative signals corresponding to the player 102a wearing the sensor unit 106a. Similarly, the motion sensing arrangements of the sensor unit 106b and the sensor unit 106c are operable to generate one or more motion-indicative signals corresponding to the player 102b and the player 102c wearing the sensor unit 106b and the sensor unit 106c, respectively.
The data recording arrangement of each of the sensor units 106 is then operable to record the corresponding motion-indicative signals as a function of time.
The motion sensing arrangements of the sensor units 106 may be operable to provide data indicative of acceleration and/or rotation and/or orientation of the players 102 as a function of time, wherefrom the aforementioned motion-indicative signals corresponding to the players 102 may be generated. For this purpose, the motion sensing arrangement of each of the sensor units 106 may include at least one of following sensors: accelerometer, magnetometer, pressure sensor, temperature sensor, gyroscopic sensor, microphone, GPS sensor or other indoor/outdoor location sensor, and timer.
For example, the motion-indicative signals corresponding to the player 102a may include information about at least one of: an ID associated with the player 102a, one or more movements (for example, accelerations and/or rotations and/or orientations) of the player 102a, one or more spatial positions of the player 102a, sound received by microphone in a sensor and associated time stamps. In addition to time stamps the received (and recorded) audio can be used for time stamping purposes. In addition recorded sound can be used to determine if a player is in motion i.e. used as motion-indicative signal.
Further, the sports monitoring system includes a data processing arrangement (not shown in FIG. 1) that is operable to receive data pertaining to the motion-indicative signals from the projectile 104 and/or at least one of the sensor units 106. The projectile 104 may be operable to communicate its recorded data (i.e., data pertaining to the motion-indicative signals corresponding to the projectile 104) to the data processing arrangement via a wireless communication link. Further, the at least one of the sensor units 106 may be operable to communicate its recorded data (i.e., data pertaining to the motion-indicative signals corresponding to the players 102) to the data processing arrangement via a wireless communication link.
The data processing arrangement is operable to perform a temporal correlation of the data so received, to determine one or more periods of time when the projectile 104 is likely to be spatially closely associated with the players 102. In accordance with an embodiment of the present disclosure, the temporal correlation is performed to determine when the players 102 have been in contact with the projectile 104 during playing of the game, and/or when mutual contact between a plurality of players from amongst the players 102 has occurred during playing of the game.
Embodiments of the present disclosure are suitable for sports such as American football, football, soccer, hockey, ice hockey, and basketball, but not limited thereto. In the example playing scenario, the sports monitoring system has been implemented for use in a game of American football, wherein the playing area corresponds to a football field, and the projectile 104 corresponds to a football. In some sports the number of projectiles in a game 104 might be more than one.
During playing of the game of American football, the player 102a holds the projectile 104 for a particular period of time, as shown in FIG. 1. The temporal correlation between the data pertaining to the player 102a and the projectile 104 enables the data processing arrangement to determine the particular period of time when the player 102a has been in contact with the projectile 104 during playing of the game. Details of how the temporal correlation is performed have been provided in conjunction with FIGS. 5 and 6.
It should be noted here that the implementation of the sports monitoring system is not limited to a specific number of projectiles and players.

Subsequently, at the step 412, the data recording arrangements of the sensor units 106 operate to record the corresponding motion-indicative signals generated at the step 410. In accordance with the step 412, the motion-indicative signals are recorded as a function of time.
Beneficially, the method includes an additional step in which at least one of the sensor units 106 and/or the projectile 104 operates to communicate its recorded data (i.e., data pertaining to the motion-indicative signals corresponding to the players 102 and/or the projectile 104) to the data processing arrangement 202 via a wireless communication link, as described earlier.
Optionally, the projectile 104 and/or the sensor units 106 may perform one or more additional steps of sharing their recorded data amongst themselves to create a virtual sensor network. Alternatively, at least one of the sensor units 106 and/or the projectile 104 may perform an additional step of collecting the recorded data from the sensor units 106 and/or the projectile 104.
Finally, at a step 414, the data processing arrangement 202 operates to receive data pertaining to the motion-indicative signals from the projectile 104 and/or at least one of the sensor units 106, and perform a temporal correlation of the data so received. Based on the temporal correlation performed at the step 414, the data processing arrangement 202 operates to determine one or more periods of time when the projectile 104 is likely to be spatially closely associated with the players 102.
In accordance with an embodiment of the present disclosure, the step 414 is performed to determine at least one of:
(a) one or more periods of time when the players 102 have been in contact with the projectile 104 during playing of the game, and/or
(b) one or more periods of time when mutual contact between a plurality of players from amongst the players 102 has occurred during playing of the game.
The step 414 may be performed either periodically or concurrently during playing of the game. Alternatively, the step 414 may be performed after the game is over.
Optionally, the method may also include an additional step of arranging for at least one of the data processing arrangement 202 and the sensor units 106 to utilize a smart telephone for their implementation within the sports monitoring system 200.
It should be noted here that the steps 402 to 414 are only illustrative and other alternatives can also be provided where one or more steps are added, one or more steps are removed, or one or more steps are provided in a different sequence without departing from the scope of the claims herein. For example, the step 402 may be performed simultaneously with the step 408. The steps 404 and 406 may be performed simultaneously with the steps 410 and 412, for example, during playing of the game.
Optionally, the method may include an additional step of collecting statistical data indicative of movements and/or spatial positions of players 102 and/or the projectile 104 as a function of time.
Optionally, the method may include an additional step of analyzing the statistical data for at least one of:
(a) editing video content recorded by the cameras, and/or
(b) providing feedback on the performance of the players 102.
Such an analysis may, for example, be performed either concurrently during playing of the game or after the game is over. Additionally consumers accessing the system could be provided performance related statistics from the venue and/or other content and information related to the game. Consumers could for example download video clips related to the game in their mobile terminal or a computer at home.
These additional steps may, for example, be performed either by the data processing arrangement 202, or by a remote server coupled in communication with the data processing arrangement 202.
FIG. 5 is an illustration of an example set of motion-indicative signals as functions of time, in accordance with an embodiment of the present disclosure. The example set of motion-indicative signals includes a motion-indicative signal 502 corresponding to the projectile 104, a motion-indicative signal 504a corresponding to the player 102a, a motion-indicative signal 504b corresponding to the player 102b, and a motion-indicative signal 504c corresponding to the player 102c. The motion-indicative signals 502, 504a, 504b and 504c have been depicted as functions of time, in FIG. 5.
The data processing arrangement 202 performs a temporal correlation between the motion-indicative signals 502, 504a, 504b and 504c, to determine at least one of:
(a) one or more periods of time when the players 102 have been in contact with the projectile 104 during playing of the game, and/or
(b) one or more periods of time when mutual contact between a plurality of players from amongst the players 102 has occurred during playing of the game.
For example, in order to determine the periods of time when the players 102 have been in contact with the projectile 104, the data processing arrangement 202 may perform the temporal correlation between the motion-indicative signals 502 and 504a, between the motion-indicative signals 502 and 504b, and between the motion-indicative signals 502 and 504c. 
The temporal correlation may, for example, be performed by way of sliding dot product. A sliding dot product may, for example, be calculated by sliding the motion-indicative signal 502 over the motion-indicative signal 504a. The value of the sliding dot product is considerably large during periods of time when the motion-indicative signals 502 and 504a substantially match with each other, i.e., when the projectile 104 is likely to be spatially closely associated with the player 102a. 
Optionally, the temporal correlation between the motion-indicative signals 502 and 504a may be performed for a suitable period of time, for example, from a starting point of the motion-indicative signals 502 and 504a. Subsequently, the temporal correlation may be iteratively performed for other suitable periods of time. Accordingly, the temporal correlation may also indicate how dependence between the motion-indicative signals 502 and 504a varies with respect to time.
Further, the data processing arrangement 202 may perform a temporal correlation between the motion-indicative signals 504a, 504b and 504c, to determine the periods of time when mutual contact between a plurality of players from amongst the players 102 has occurred.
FIG. 6 is an illustration of results of the temporal correlation performed on the example set of motion-indicative signals, in accordance with an embodiment of the present disclosure. With reference to FIG. 6, the results of the temporal correlation performed on the motion-indicative signals 502, 504a, 504b and 504c are indicative of the following:
(a) the projectile 104 is likely to be spatially closely associated with the player 102a during a period of time (t2) and a period of time (t3),
(b) the projectile 104 is likely to be spatially closely associated with the player 102b during a period of time (t1) and a period of time (t4), and
(c) the projectile 104 is likely to be spatially closely associated with the player 102c during a period of time (t5).
Based on the results of the temporal correlation, statistical data on when the players 102 have been in contact with the projectile 104 may be derived.
Further, results of the temporal correlation performed on the motion-indicative signals 504a, 504b and 504c may be indicative of the periods of time when mutual contact between a plurality of players from amongst the players 102 has occurred. The results may, for example, be indicative of one or more periods of time when a plurality of players moved in sync with each other. For example, a plurality of players involved in a tackle situation may be moving with apparently large accelerations and/or in the same direction at the same time.
Embodiments of the present disclosure can be used for various purposes, including, though not limited to, enabling users to know when one or more players have been in contact with one or more projectiles during playing of the game, and/or when mutual contact between a plurality of players has occurred during playing of the game, and enabling users to collect statistical data indicative of movements and/or spatial positions of the players and/or the projectiles as a function of time, and thereby further analyze the statistical data, for example, to provide feedback on the performance of the players and/or to edit video content recorded by various cameras concurrently during playing of the game.
