Abstract
Disclosed is a method or device for recognizing a structure, preferably a bead or trace of adhesive material (20), which is to be applied to a substrate (30), with the aid of at least two cameras, more particularly three or more cameras (12, 13, 14). The structure, which is to be applied, is applied to the substrate using an applicator device (11), whereupon the structure, which is applied to the substrate by means of the applicator device, is monitored by the cameras in such a way that the cameras are oriented towards the applied structure with at least one overlapping area, wherein the applied structure, particularly the edges of the trace of adhesive, is determined on a revolving orbit around the applicator device and the revolving orbit is pre-defined in such a way that the applied structure intersects the revolving orbit after it has been applied to the substrate.
