ABSTRACT:
A method of alignment of two parts comprises separating the two parts and producing images of the separated parts, breaking down the images into image points with a spacing smaller than the required accuracy, digitalizing the information content of the image points and comparing the actual position of the parts, taking into account the initial separation, and moving the two parts, into alignment from the results of the comparison.
