Measuring Arrangement for Measuring Three Dimensional Location and Orientation of The Center Axis of First Axle in Relation to The Center Axis of Second Axle

摘要

A measuring arrangement includes a positioning arrangement including at least one locator, at least one first spot to be located, at least one second spot to be located, and a position data gathering unit for gathering a first set of at least three different position data measurements of each of the at least one first spot to be located, wherein the different position data measurements are taken in different rotation angles around a first axle, and a second set of at least three different position data measurements of each of the at least one second spot to be located, wherein the different position data measurements are taken in different rotation angles around a second axle. The three dimensional location and orientation of the center axis of the first axle with respect to the center axis of the second axle are determined on the basis of the first and second set of position data measurements.
