Assignee: 7-ELEVEN, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 13:
14. The method of claim 8, wherein recomputing the homography comprises:
receiving a first (x,y) coordinate identifying a first x-value and a first y-value in the global plane where a first marker is located in the space, wherein the first marker is a first object identifying a first location in the space;
receiving a second (x,y) coordinate identifying a second x-value and a second y-value in the global plane where a second marker is located in the space, wherein the second marker is a second object identifying a second location in the space;
receiving a second frame from the first sensor;
identifying the first marker and the second marker within the second frame;
determining a third pixel location in the second frame for the first marker, wherein the third pixel location comprises a first pixel row and a first pixel column of the second frame;
determining a fourth pixel location in the second frame for the second marker, wherein the fourth pixel location comprises a second pixel row and a second pixel column of the second frame; and
recomputing the first homography based on the first (x,y) coordinate, the second (x,y) coordinate, the third pixel location, and the fourth pixel location.
