A method is provided for determining the geometry of one or more real, examined defects of a metallic and in particular magnetizable object, in particular a pipe or a tank, by means of at least two reference data sets of the object generated on the basis of different, non-destructive measuring methods.

Method for determining the geometry of a defect and for determining a load limit

A method is provided for determining the geometry of a metallic object, with in particular one or more real, examined defects, with a reference data set of the object generated on the basis of at least one measurement by at least one non-destructive measuring method, preferably comprising an at least partial representation of the object on or by an at least three-dimensional object grid by means of a computer unit. A classification of anomaly-free areas and anomaly-affected areas of the object is performed on the basis of at least parts of the at least one reference data set. An initial object grid is created, a prediction data set of the at least one non-destructive measurement method is calculated by a simulation routine using the initial object grid, at least parts of the prediction data set are compared with at least parts of the at least one reference data set, excluding the anomaly-afflicted regions, and the initial object grid is used as an object grid describing the geometry of the object as a function of at least one accuracy measure, or the initial object grid is iteratively adapted to the geometry of the object in the anomaly-free regions by means of the EDP unit.
