  • Patent number: 7046348
    Abstract: The invention relates to a device for measuring color, luster and undulations on lacquered freeform surfaces at a predetermined target distance and symmetrically in relation to the measuring point normal lines at a measuring point. Said device is characterized by the provision of a measuring head that can be displaced in three dimensions by at least one motor and that comprises a measuring-head axis, a light emitter and a video camera. The light emitter is provided with a planar light pattern that is to be emitted along its illumination axis. An evaluation unit is provided for the light pattern (reproduction pattern) of the light emitter that is reproduced in the video camera, said evaluation unit emitting a control signal which is dependent on and formed from the distortion produced or the migration of the reproduction pattern.
