Filtering method for improving the data quality of geometric tire measurements

A tire measurement system for processing measurement characteristics associated with a given tire rotated at one or more predetermined speeds, said tire measurement system more particularly comprising:

• a first memory adapted for storing measurements, each measurement corresponding to a geometric parameter value obtained at an angular position relative to the given tire;
• a second memory adapted for storing software in the form of computer-executable instructions;
• and
• at least one processor coupled to said first and second memories and configured to selectively implement the computer-executable instructions stored in the second memory to process the measurements stored in the first memory;
• wherein said at least one processor implements the computer-executable instructions stored in said second memory in order to implement the functions of:
• identifying selected ones of the geometric parameter values that lie on a convex hull surrounding the entire set of values, and interpolating the identified selected ones of the geometric parameter values that lie on the convex hull to obtain a final data set of filtered measurements
• wherein said it least one processor is further configured to transform the plurality of geometric parameter values into two-dimensional form by characterizing the geometric parameter values in terms of a curvature location along the surface of the given tire measured in first and second orthogonal directions.
