Method for representing the surface of an object

1. A method for representing a surface of an object ( 1 ), comprising the steps of

measuring actual 3D data ( 6 ) using at least one of an optical or tactile 3D measurement device;

determining actual 3D data ( 7 ) of a defect in the surface of the object ( 1 ) based on a mean value formation from the measured actual 3D data ( 6 ), wherein the actual 3D data and the measured actual 3D data are different sets of data;

modifying by a computer desired 3D data ( 5 ) of the defect of the surface of the object ( 1 ) based on the actual 3D data ( 7 ) of the surface of the object ( 1 ) to generate a modified desired 3D data;

and generating by the computer 3D representation data that is comprised of the desired 3D data ( 5 ) of the surface of the object ( 1 ) and the modified desired 3D data of the surface of the object, the 3D representation data displays a 3D image of the surface of the object, wherein the modified desired 3D data depicts a region of the defect in the surface of the object and the desired 3D data depicts an outside region of the region of the defect.

2. The method in accordance with claim 1 , wherein the desired 3D data ( 5 ) are modified in one or more specific regions of the object ( 1 ).

3. The method in accordance with claim 2 , wherein the specific region(s) are predetermined and/or determined interactively.

4. The method in accordance with claim 2 , wherein the specific region(s) are determined by an examination of the actual 3D data ( 5 ) for surface defects.

5. The method in accordance with claim 1 , wherein the desired 3D data are modified by a refining of the desired 3D data and/or by a change of normal vectors of the desired 3D data.

6. The method in accordance with claim 1 , wherein the desired 3D data ( 5 ) and/or the actual 3D data ( 7 ) and/or the modified desired 3D data are present as CAD data.

7. The method in accordance with claim 1 , wherein the 3D representation data are processed prior to a representation.

8. The method in accordance with claim 1 , wherein a representation of the object ( 1 ) takes place from a selectable position of an observer.

9. The method in accordance with claim 1 , wherein a representation of the object ( 1 ) takes place using a selectable surface characteristic, wherein the selectable surface characteristic includes a material of the surface, a color of the surface, or a degree of shine of the surface.

10. The method in accordance with claim 1 , wherein a representation of the object ( 1 ) takes place using a selectable illumination characteristic.

11. The method in accordance with claim 1 , wherein a representation of the object ( 1 ) takes place using a selectable environmental characteristic, wherein the environmental characteristics that are selectable include surrounding walls, a color of the walls, and a degree of reflection of the walls.

12. The method in accordance with claim 1 , wherein a defect representation is superimposed on a representation of the object ( 1 ).

13. The method in accordance with claim 3 , wherein the specific region(s) are determined by an examination of the actual 3D data ( 5 ) for surface defects.

14. The method in accordance with claim 13 , wherein the desired 3D data are modified by a refining of the desired 3D data and/or by a change of normal vectors of the desired 3D data.

15. The method in accordance with claim 4 , wherein the desired 3D data are modified by a refining of the desired 3D data and/or by a change of normal vectors of the desired 3D data.

16. The method in accordance with claim 3 , wherein the desired 3D data are modified by a refining of the desired 3D data and/or by a change of normal vectors of the desired 3D data.

17. The method of claim 1 , wherein the desired 3D data ( 5 ) of the surface of the object is data that represents a desired version of the surface of the object, the desired 3D data ( 5 ) is a distinct and unrelated set of data from the actual 3D data ( 7 ) and the measured actual 3D data ( 6 ).

18. The method of claim 9 , wherein the material of the surface includes paint, anodization, or chromium plating.

19. The method of claim 1 , further comprising:

visualizing the surface of the object with a simulated coated surface; and

viewing the surface of the object in a selectable environment,

wherein a position of a user visualizing the simulated coated surface is changeable.

20. The method of claim 19 , wherein the selectable environments include a showroom, a city, a country, or a quality room.
