Patent ID: 8016653

Claim:
A method of filtering data taken from a sporting event, the data indicating a position of a moving object, the method comprising the steps of: (a) generating a position of the moving object by obtaining a first estimate of the data indicating a position of the moving object by measuring a position of the moving object; (b) obtaining a first prediction of the precision of the first estimate; (c) obtaining a second estimate of the data indicating a position of the moving object by extrapolating a position of the moving object based on one or more prior positions of the object; (d) obtaining a second prediction of the precision of the second estimate; (e) obtaining a third estimate of the data indicating a position of the moving object using historical data indicating a reference line representing an estimate of a path traveled by object at an earlier time; (f) obtaining a third prediction of the precision of the third estimate; (g) obtaining a fourth estimate of the data indicating a position of the object based on the first, second and third estimates and the first, second and third predictions; and (h) transforming the first position of the moving object generated in said step (a) based on the estimates and precision of the estimates obtained in said steps (b) through (g).
