ABSTRACT:
An on-line method for determining the wood-bark ratio in a flow of material containing both wood and bark includes illuminating the flow of material and scanning using a CCD camera, by means of which 30-300 image pixels/cm are obtained in the transverse direction of the flow of material. Narrow transverse groups of 1-20 adjacent pixels, in which the brightness of the pixels deviates from a preset criterium are filtered out of the transverse group of pixels and the calculation of the wood-bark ratio of the photographs takes place without these narrow groups.
