Verfahren zur gesteuerten Darstellung von Oberflaechen

The method involves recording several single pictures circumferentially orientated at the curved surface of a cavity (H) at different axial positions. An axially inserted recording apparatus (S,E) is used for the pictures which are temporarily stored in an image storage. Several sub-areas are extracted from the recorded single pictures in the storage and are joined together after transformation (Tr1,Tr2). A predetermined viewing direction is calculated as a flat presentation of at least one section of the surface outside the cavity and displayed. USE - For visual inspection of e.g. drillings, pipes. ADVANTAGE - Enables fast and visual inspection of curved surface and allows entire surface or section of surface to be presented optically.
