Abstract

The invention relates to a device for evaluating a characteristic of an object. Said device comprises a system (10) for preparing a three-dimensional representation of an object, said representation containing information about the characteristic to be evaluated. The three-dimensional representation is sub-divided into a plurality of partial areas (12) which are then evaluated one by one, each partial area of the plurality of partial areas being examined (14) in a two-dimensional manner, in order to determine data relating to a location in a partial area, in which the characteristic differs from a pre-determined characteristic. Using the data relating to the locations in the individual partial areas, a three-dimensional coherence analysis (16) provides a three-dimensional description of a three-dimensional location, the characteristic of said location differing from the pre-determined characteristic. By sub-dividing the three-dimensional representation into a plurality of partial areas which can be analysed in a two-dimensional manner, effective image processing algorithms can be used. The three-dimensionality can then be achieved again by means of a coherence analysis of the two-dimensional data. In this way, a geometrical reference model is superfluous and the resulting high requirement for memory and calculation time is eliminated.
