Patent ID: 8064069

Claim:
A method for measuring the shape of a reflective surface ( 14 ) with a system which comprises at least one pattern ( 15 ) for reflection at the reflective surface ( 14 ) and at least one camera ( 1 ) for viewing, pixel by pixel, the pattern ( 15 ) which is reflected at the surface ( 14 ), wherein the position and the orientation of the camera ( 1 ) and of the pattern ( 15 ) are known, characterized in that from the viewing directions of the camera ( 1 ), which are known for the pixels ( 8 ), and the positions of the pattern ( 15 ), which correspond to the mapping of the reflected pattern ( 15 ) on the pixels ( 8 ) of the camera ( 1 ), the surface angle and the surface height are determined for the purpose of measuring of the shape; characterized in that for the accurate determination of the surface height, a defined pattern point is covered by a marker, which is arranged in front of the pattern to identify exactly the surface point, and the absolute surface height of the surface point which reflects the marker is determined.
