Claim 13:
14. The method of claim 8, further comprising:
receiving a third (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 fourth (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 first frame from the sensor;
identifying the first marker and the second marker within the first frame;
determining a first pixel location in the first frame for the first marker, wherein the first pixel location comprises a first pixel row and a first pixel column of the first frame;
determining a second pixel location in the first frame for the second marker, wherein the second pixel location comprises a second pixel row and a second pixel column of the first frame;
generating the homography based on the third (x,y) coordinate, the fourth (x,y) coordinate, the first pixel location, and the second pixel location; and
storing the homography.
