Abstract

Assigning measuring points to fixed points includes calculating fixed point distances between fixed points in a fixed point coordinate system; determining coordinates of measuring points in a measuring point coordinate system; calculating measuring point distances between the measuring points; comparing at least two measuring point distances with the fixed point distances and identifying at least two pairs each consisting of a measuring point distance and a fixed point distance; determining a reference point in the measuring point coordinate system or in the fixed point coordinate system; determining first and second reference point parameters of the measuring points or fixed points corresponding to the pairs; determining second reference point parameters of the fixed points corresponding to the pairs in the fixed point coordinate system; identifying correspondences between the first reference point parameters and the second reference point parameters and assigning the corresponding measuring points to the corresponding fixed points.
