| 摘要 |
The present invention deals with indicating at least one of an orbit of, and a deviation from a nominally round surface of a mechanical object (7) by generating and indicating a deviation profile (21) based on distance data sets covering the nominally round surface; each distance data set comprising at least three distances, measured in a direction of rotation, to the surface and related to an angle, the at least three distances having been measured at distance measuring angles; and weights related to the distance measuring angles. The present invention may be used to indicate the quality of the surface/mechanical object, or to indicate status of manufacturing equipment. It also relates to a computer program product comprising the method, a carrier comprising the computer program product, storage means comprising distance data, and a device for measuring distance data sets being used as input to a device according to the first aspect.
