Claim:
1. A method for measuring a three-dimensional object, comprising the steps of: stationarily fixing an object to a holder rotatable about an axis of rotation; rotating the holder with the objected fixed thereon about the axis of rotation; scanning an end face of the object disposed transversely to the axis of rotation with a sensing device, while the object is rotated about the axis of rotation; moving the sensor device relative to the holder linearly along a translation axis forming an acute angle with the axis of rotation and defining a plane within which the sensing device is moved; detecting positions of the sensor device; and determining a location of a reference axis of the object and then subsequently determining a contour of the end face in reference to an axial run-out of the object relative to the reference axis based on detected positions of the sensing device.
