The invention relates to a method, the method comprises exposing an image frame of an object to be monitored by an area image sensor, transmitting a part of the exposed image frame to an image data processing device, analyzing the part and if the part is detected to comprise a predefined event, said image data processing device is arranged to transmit a trigger signal for triggering said area image sensor so that said area image sensor transmits a bigger part of at least one further image frame to said image data processing device for further analysis, and if not the area image sensor continues to expose at least one further image frame and to transmit a part of said at least one exposed further image frame. The invention further relates to a machine vision system for performing the method and a computer program product comprising instructions to perform the method.

The invention relates to a beam structure (40) to be used in web monitoring or defect detection and to be placed in the vicinity of a movable web (51) in the transverse direction, for example, in relation to a paper or cardboard machine, to support at least one functional element used in the web monitoring. The beam structure (40) comprises at least two carbon fibre composite beam modules (10) with a monolithic profile, their longitudinal side comprising an installation opening (12) for at least one functional element. The beam modules (10) can be installed one after the other in the longitudinal direction, wherein each beam module (10) constitutes a part of the uniform beam structure (40) so that the installation openings (12) of the beam modules (10) are aligned in the beam structure (40). The invention also relates to a carbon fibre composite module (10) to be used in the beam structure (40).
