FLEXIBLE CAMERA INTERFACE

摘要

The invention relates to a method for coupling a camera unit (11−18) to communicate with an image processing unit (20) that represents and/or analyzes and/or stores image information in a system monitoring the manufacturing or finishing process of a continuous fibrous web, said control system comprising one or several camera units (11−18) connected to at least one image processing unit (20). In the camera interface according to the invention an image signal (31, 40, 50) received from a single camera unit (11−18) is transformed in the vicinity of said camera unit (11−18) into a series mode digital signal (38) which has a standard frame structure and is independent on the type of the camera unit, and said series mode signal (38) with a standardized frame structure is transmitted further to the image processing unit of the control system by means of undisturbed optical connection (29). Thus, by means of the invention the interface used for transmission of data is standardized in the signal receiving end, i.e. in the image processing unit (20) both for the part of its transfer path and for the part of the format used in the transfer path for transmission of data. When compared to the related art, the invention enables a more flexible and undisturbed coupling of camera units of different types to a control system when building up, modernizing or adjusting said system to changing operating conditions.
