Abstract
The method uses a lighting unit consisting of one or several lighting arrangements (B1, Bn) brought into a first spatial constellation (43a,43b) to illuminate an arbitrary object surface (20), and a recording unit consisting of one or several image receivers (K1,Kn) in a second spatial constellation, which record images of the illuminated arbitrary object surface. The arbitrary object surface or the object carrying it, is brought into a spatial position (42) which matches with the first and second constellation of the lighting unit and the recording unit in such way, that an application-specific, predetermined surface recording is possible, at least uniformly for a first surface area of the object. USE - In automatic quality control. ADVANTAGE - Enables application-specific recording of arbitrary areas of object surface.
