Abstract
A method is provided for combining a first physical object and a second physical object. A first locating point is defined on a first physical object, and a first location of the first locating point is determined by taking at least two measurements with respect to a Cartesian coordinate system. Similarly, a second locating point is defined on a second physical object. After combining the first physical object with the second physical object, a second location of the second locating point is determined by taking at least two measurements. The Cartesian measurement data is transformed into vector data before mean values, including directional mean values, are generated by performing statistical analysis in a Polar coordinate system. The first location can then be analyzed with respect to the second location using these mean values. This method can be applied to numerous applications, including the assembly of two manufactured automotive parts, exact color match of paint, or assessing the fit between an implant abutment and the prosthesis framework.
