A computer-implemented method and apparatus for automatically generating tagged image data and analyzer for inspecting a component

The present invention relates to automatic generation of tagged image data. For this purpose, a visual representation of the component is calculated on the basis of already existing design data for a component, wherein the surface properties of the visual representation of the component can be varied based on predetermined characteristic properties. Since the calculation of such visual representations both the component itself, and the underlying characteristic surface properties are known, this information can be used to identify the corresponding parts in the visual representation to allow automatic identification of the calculated visual representation.
