Specifically, the disclosure is directed to a system of sensors coupled to a basketball backboard adapted to provide an accurate tracking of a shot in a given three-dimensional space and extract features manipulated to yield key performance indicators based on establishing whether, how often and where the ball center passes the rim plane at a sub-cm resolution over a period of no more than 200 msec. ## Claims ### Claim 1 A system for assisting a referee in officiating a basketball game, the system comprising: a. a transparent board having a front surface and a rear surface; b. a hoop operably coupled to the transparent board, wherein the hoop rim defines a plane that is perpendicular to the board; c. a sensing module coupled to the board, wherein the sensing module is adapted to trace a course of a ball over a predetermined voxel; d. a basketball game time administration means; and e. a processing module, in communication with at least one of: the sensing module, the board and the rim, and the basketball game time administration means, the processing module having a central processing unit in communication with a non-volatile memory having thereon a processor-readable medium with a set of executable instructions configured, when executed by at least one processor, to: i. track the course of the ball within the predetermined voxel; ii. determine the location of the center of the ball; iii. trace the ball center within the predetermined voxel; iv. determine the ball center location relative to the hoop rim; v. determine the planar location of the ball center on the rim plane where the ball center crosses; vi. plotting a time versus location of the ball center in relation to the hoop rim; vii. once the ball passes the hoop rim beyond a threshold defined by the user, viii. determine a shot was blocked ix. determine goal tending; and x. determine board shaking. ### Claim 2 (depends on 1) The system of claim 1, wherein the basketball game time administration means is at least one of a shot-clock, an audible marker, a display, and a visual marker. ### Claim 3 (depends on 2) The system of claim 2, wherein the set of executable instructions is further configured, when executed by at least one processor, to: a. once the ball center passes the hoop rim beyond a user-defined threshold, communicate to the referee the time to the basketball game time administration means; and b. stop the period allotted for the shot to take place. ### Claim 4 (depends on 3) The system of claim 3, wherein the set of executable instructions is further configured, when executed by at least one processor, to determine at least one of: a. ball deflection; b. ball center passing an apex; c. ball touching the backboard; d. ball touching the hoop's rim; and e. ball center passing above the hoop's rim cylinder. ### Claim 5 A method of assisting a referee in officiating a basketball game, implemented in a system comprising: a transparent board having a front surface and a rear surface; a hoop operably coupled to the transparent board, wherein the hoop rim defines a plane that is perpendicular to the board; a sensing module coupled to the board, wherein the sensing module is adapted to trace a course of a ball over a predetermined voxel; a basketball game time administration means; and a processing module, in communication with at least one of: the sensing module, the board and the rim, and the basketball game time administration means, the processing module having a central processing unit in communication with a non-volatile memory having thereon a processor-readable medium with a set of executable instructions configured, when executed by at least one processor, to: track the course of the ball within the predetermined voxel; determine the location of the center of the ball; trace the ball center within the predetermined voxel; determine the ball center location relative to the hoop rim; determine the planar location of the ball center in relation to the hoop's rim plane where the ball center crosses; plotting a time versus location of the ball center in relation to the hoop's rim; once the ball passes the hoop's rim beyond a threshold defined by the user, determine a shot was blocked determine goal tending; and determine board shaking, the method comprising providing at least one of: the referee, and the basketball game time administration means, at least one of: a. an indication of goal tending; b. an indication of the time the ball center passes the hoop rim beyond a user-defined threshold; c. an indication a player has blocked a shot beyond the ball center reaching an apogee; d. an indication a player hit the transparent backboard. ### Claim 6 (depends on 5) The method of claim 5, wherein the basketball game time administration means is at least one of a shot-clock, an audible marker, a display, and a visual marker. ### Claim 7 (depends on 5) The method of claim 5, further comprises providing at least one of: the referee, and the basketball game time administration means, at least one of: a. an indication the player vibrated the hoop's rim; and b. an indication the player vibrated the hoop's rim net. ### Claim 8 (depends on 7) The method of claim 7, further comprising resetting the shot-clock. ### Claim 9 (depends on 1) The system of claim 1, wherein the sensing module comprises one or more of an optic sensor, a proximity sensor, and/or an acceleration sensor. ### Claim 10 (depends on 9) The system of claim 9, wherein the sensing module comprises an optical sensor chosen from one or more of LIDAR, laser detection, optical radar, or a digital camera. ### Claim 11 (depends on 9) The system of claim 9, wherein the sensing module comprises one or more cameras chosen from a digital RGB camera, an IR camera and an IR laser projector. ### Claim 12 (depends on 1) The system of claim 1, further comprising balls with RFID tags. ### Claim 13 (depends on 1) The system of claim 1, wherein the sensing module further measures at least one KPI. ### Claim 14 (depends on 5) The method of claim 5, wherein the sensing module comprises one or more of an optic sensor, a proximity sensor, and an acceleration sensor. ### Claim 15 (depends on 14) The method of claim 14, wherein the sensing module comprises an optical sensor chosen from one or more of LIDAR, laser detection, optical radar, or a digital camera. ### Claim 16 (depends on 15) The method of claim 15, wherein the sensing module comprises one or more cameras chosen from a digital RGB camera, an IR camera and an IR laser projector. ### Claim 17 (depends on 5) The method of claim 5, further comprising balls with RFID tags. ### Claim 18 (depends on 5) The system of claim 5, wherein the sensing module further measures at least one KPI.
