The invention refers to a method, and a device, to be used in sorting plant for saw timber in order to measure the dimension, profile and other properties of individual logs and thereby improving the sawyield. The method comprises an image analysis system and at least one further measuring system, which are used to determine the wood surface profile under the bark of the log end, whereby the wood surface profile, obtained with the image analysis, is combined with another wood surface profile, obtained with another measuring technique, or the image analysis utilizes measurement results obtained from another measurement to determine the wood surface profile.

L'invention concerne un procédé, et un dispositif, destinés à être utilisés dans le tri du bois de sciage afin de mesurer les dimensions, le profil et autres propriétés de différents bois ronds et ainsi d'améliorer le rendement de sciage. Le procédé comprend un système analyseur d'image et au moins un autre système de mesure qui sont utilisés pour déterminer le profil superficiel de bois sous l'écorce de l'extrémité du bois rond. Le profil superficiel de bois, obtenu par l'analyse d'image, est combiné à un autre profil superficiel de bois, obtenu par une autre technique de mesure, ou bien l'analyse d'image utilise des résultats de mesure obtenus par une autre mesure pour déterminer le profil de surface de bois.
