Claim One:
1. A method for the inspection of surfaces of an examined object, comprising the steps of: calibrating an area image sensor three-dimensionally onto a selected coordinate system; calibrating an illuminating unit three-dimensionally onto the selected coordinate system; illuminating a surface of an object using the calibrated is illuminating unit; capturing images of the illuminated surface using the calibrated area image sensor while the surface is moved relative the calibrated area image sensor; and forwarding the captured images to an image analysis unit configured to ascertain surface anomalies as defect areas in a detection as well as to delimit, if required, the defect areas in a segmentation relative to other defect areas or against an image background, to summarize defect areas belonging together in a regional analysis, to derive characteristic defects from defect areas or defect wherein the step of illuminating includes projecting a pattern is onto an area of the surface of the object, which area is captured by the calibrated area image sensor in the step of capturing; and wherein a position of defined pattern portions of the projected pattern on the surface of the object is determined in the selected coordinate system.
