Abstract
A computer-controlled machine equipped with sensors determines position and orientation of a workpiece, with respect to a model of the workpiece, which is stored in a data processing system interfaced to the machine, by measuring coordinates of points on the surfaces of the workpiece and determining a transformation in which a sum of squared distances from the points to the corresponding surfaces of the model is minimized. The determined transformation is improved so as to satisfy the specified tolerances.
