<p>The invention relates to a method and an apparatus for defining the amount of wood material present in a bark flow coming out from debarking and for controlling a debarking process on the basis of said data for reducing wood losses in the debarking process. In the apparatus of the invention, a bark flow emerging from debarking is adapted to be imaged by means of a camera (6), said image taken by the camera being adapted to be processed with an image processing unit (8) which uses different whitenesses of the picture elements or pixels of the image as a basis for defining programmatically the amount of wood material in the bark flow. The image processing unit (8) is adapted to produce an output signal (9) for controlling the debarking process. In addition, the invention relates to a method and an apparatus for defining the amount of wood material in a bark flow being moved to a combustion process and for controlling the combustion process on the basis of said data.</p> |
