ABSTRACT:
A method of making a series of measurements of the relative position of a point on the surface of an object in an object related coordinate system is disclosed. The object is turnable around an axle. The point, which moves between each measurement, is measured by an optical distance and angle measuring device which is placed each time in an arbitrary position in an earth-related coordinate system. The measurements of the position of said point are transformed from an earth related coordinate system to the object related coordinate system. By comparing the current measurement of the point with past measurements of the point, the wear on the surface of the object can be determined.
