Counting gaming chips

Abstract

An image can be captured from an imaging device. A gaming chip tube can be identified in a gaming chip tray. A first position can be determined that corresponds to a bottom of the gaming chip tube. A spacer can be identified by recognizing a predefined pattern on the spacer. A second position can be determined corresponding to the spacer. A count of gaming chips can be determined based at least in part on the first and second positions.

1 . A system comprising:
 at least one imaging device; and   at least one computing device coupled to the at least one imaging device; wherein:
 the at least one imaging device is configured to capture at least a portion of a gaming table to generate an image; and 
 the at least one computing device is configured to:
 obtain the image from the at least one imaging device; 
 identify a gaming chip tube in a gaming chip tray; 
 determine a first position corresponding to an end of a plurality of the gaming chips stacked in the gaming chip tube; 
 identify a spacer based at least in part on recognizing a predefined pattern on the spacer; 
 determine a second position corresponding to the spacer; and 
 determine a first count of the gaming chips in the gaming chip tube based at least in part on the first position and the second position. 
 
   
     
     
         2 . The system of  claim 1 , wherein the at least one computing device is further configured to:
 identify a second gaming chip tube in the gaming chip tray;   determine a third position corresponding to an end of a plurality of the gaming chips stacked in the second gaming chip tube;   identify a second spacer based at least in part on recognizing the predefined pattern on the second spacer;   determine a fourth position corresponding to the second spacer; and   determine a count of gaming chips in the second gaming chip tube based at least in part on the third position and the fourth position.   
     
     
         3 . The system of  claim 1 , further comprising at least one second imaging device, wherein the at least one second imaging device is configured to capture at least a portion of the gaming chip tray, and the at least one computing device is further configured to:
 obtain a second image from the at least one second imaging device;   determine a third position corresponding to the end of the plurality of the gaming chips in the second image;   identify the spacer based at least in part on recognizing the predefined pattern on the spacer in the second image;   determine a fourth position corresponding to the spacer identified using the second image; and   determine a second count of the gaming chips in the gaming chip tube based at least in part on the third position and the fourth position.   
     
     
         4 . The system of  claim 3 , wherein the at least one computing device is further configured to:
 determine that the second count of the gaming chips fails to match the first count of the gaming chips; and   perform a remedial action responsive to the determination that the first count fails to match the second count.   
     
     
         5 . The system of  claim 1 , wherein the predefined pattern on the spacer differs from a pattern on any of a plurality of denominations of the gaming chips. 
     
     
         6 . The system of  claim 1 , wherein the at least one computing device is further configured to calculate a delta between the first position and the second position, and determine the count of the gaming chips by rounding a result of the delta divided by a predefined gaming chip size. 
     
     
         7 . The system of  claim 1 , wherein the end of the plurality of the gaming chips corresponds to a bottom of the gaming chip tube.
