Abstract

This report describes methods for generating test data sets and reference results which can be used to test assessment software employed in coordinate metrology for finding least-squares best-fit curves and surface to data. The methods do not rely on the use of reference software but instead exploit known mathematical properties which hold at the solution of the data approximation problem. The methods are flexible, straightforward to implement and should be of value in designing conformance testing procedures. The methods are illustrated for the problem of finding the least-squares best-fit circle to data.
